Why Kimchi?

Kimchi is the AI platform inside CAST AI. We started by helping companies run LLMs on their own Kubernetes clusters - now we're building the execution layer where agents do real work.

Our Infrastructure today: multi-model inference (MiniMax, Kimi, GLM-5, Nemotron, DeepSeek) with intelligent routing, an OpenAI-compatible API, and deployment flexibility from our GPUs to your VPC. The inference layer is the foundation. What we're hiring for sits on top of it: coding agents, agent runtimes, orchestration systems, and the reliability engineering that makes them actually finish things.

Tech Stack: TypeScript, Go, Kubernetes, AWS/GCP/Azure, MCP, Prometheus/Grafana/Loki, GitLab CI, ArgoCD.

Why harness engineering matters here
OpenAI and Anthropic ship models. They also ship one harness each - the scaffolding that turns a raw model into something that can plan, execute, recover, and complete work. We ship a different kind of harness: one built for cost-conscious, long-horizon autonomy, running on inference infrastructure we control end-to-end.
A decent model with a great harness beats a great model with a bad harness. We've watched this play out. The gap between what today's models can do and what you see them doing is largely a harness gap - and that gap is where we operate.

What you'll build
The ratchet.
Every time our agent makes a mistake, we engineer a solution so it never makes that mistake again. That means hooks that enforce constraints the model "knows" but forgets: pre-commit lint checks, permission gates, context compaction before the window fills. Success is silent, failures are verbose.

Long-horizon execution.
Our harness is built around spec-driven autonomy: meta-prompting, fresh context per task, worktree-per-slice git strategy, automatic replanning, crash recovery, stuck detection. We're implementing Ralph loops - when the model tries to exit, we intercept and reinject the goal into a fresh context. The agent reads state from disk and continues. Multi-session, multi-day work, without context rot.

Planner/executor splits.
Planning with a reasoning model, executing with a fast one, evaluating with a third. Separating generation from evaluation beats self-verification because agents reliably skew positive when grading their own work.

The harness surface.
CLI, TUI, MCP integration, sandboxed execution, telemetry. Our AGENTS.md is short - every line traces to a specific thing that went wrong. TypeScript on the surface, Go where it matters.

Memory and context.
Moving agents off laptops, giving them state that survives across sessions, managing context so information lands where it's actionable. Compaction, tool-call offloading, progressive skill disclosure.

What makes this different (with receipts)
You've seen the pitch: "we route to the best model." Everyone says that. Here's what we actually have:

• GPU infrastructure we own. Not just an API reseller. From GPU placement across clouds to the inference endpoint your agent calls - we control the cost curve.
• A harness-first thesis. We treat agent failures as configuration problems, not model problems. When we moved from a stock harness to our own, completion rates on internal benchmarks improved by 40%+ on the same model.
• Agents.md that earns every line. No brainstormed rules - every constraint in our system prompt traces to a real failure we saw and fixed.

Requirements:

• You've used AI coding agents in anger. Not demos - real work. You have opinions about Claude Code, Codex, OpenCode, Cursor. You know what it feels like when an agent gets stuck and why.
• Strong TypeScript or Go in production. Comfort moving between them. Our surface is TypeScript; our core is Go.
• You think in harness terms. You read "the agent hallucinated" and your first instinct is to ask what context it was missing, what hook should have caught it, what constraint should exist.
• You drive features end-to-end. Design → build → ship → measure → iterate. We don't have layers that absorb ambiguity for you.

Responsibilities:

• Build and evolve the agent harness - ship hooks, permission gates, and context compaction. Every AGENTS.md constraint traces to a failure you personally diagnosed.
• Own long-horizon execution - multi-session task completion via spec-driven prompting, worktree-per-slice git, Ralph loop recovery, and stuck detection. Completion rate is your metric.
• Architect planner/executor/evaluator pipelines - planning with a reasoning model, execution with a fast one, evaluation with a third. No self-verification.
• Manage agent memory and context - state persistence across sessions, context compaction, tool-call offloading. Zero context rot on multi-day work.
• Own the harness surface - CLI, TUI, MCP integrations, sandboxed execution, telemetry. TypeScript on the surface, Go where it matters.

What success looks like (after 6 months):

• You've shipped at least one major harness feature end-to-end: designed it, built it, measured it, iterated.
• You've added constraints to our AGENTS.md based on failures you personally observed and diagnosed.
• You've improved a measurable reliability metric - completion rate, context efficiency, or cost per successful task.
• You've formed strong opinions about where our harness is load-bearing and where it's dead weight.

What’s in it for you?

• Competitive salary (€6,500 - €9,000 gross, depending on the level of experience).
• Enjoy a flexible, remote-first global environment.
• Collaborate with a global team of cloud experts and innovators, passionate about pushing the boundaries of Kubernetes technology
• Equity options.
• Get quick feedback with a fast-paced workflow. Most feature projects are completed in 1 to 4 weeks.
• Spend 10% of your work time on personal projects or self-improvement. 
• Learning budget for professional and personal development - including access to international conferences and courses that elevate your skills.
• Annual hackathon to spark new ideas and strengthen team bonds.
• Team-building budget and company events to connect with your colleagues.
• Equipment budget to ensure you have everything you need.
• Extra days off to help maintain a healthy work-life balance.

This is a location-specific opportunity. We are currently accepting applications from candidates residing in the following European countries: Bulgaria, Croatia, Estonia, Greece, Hungary, Latvia, Lithuania, Poland, Romania, Slovakia, Slovenia, and Ukraine.

#LI-Remote

This is a high-bar IC role on a team building Data APIs, custom visualisations, and AI products that sit at the core of how hoteliers understand and act on their revenue data. You'll work across the full stack — from problem discovery with Product through to production monitoring — and you'll bring the engineering judgment to navigate legacy code, build new systems when needed, and raise the bar for the engineers around you. We care more about how you think than which languages you've used, though Java proficiency is required.

What Makes Us Different?

Duetto is the hospitality industry's leading revenue management platform, founded in 2012 by former Wynn Resorts executives who knew the industry needed better technology. We built the world's first Revenue & Profit Operating System — a suite of tools (GameChanger, ScoreBoard, BlockBuster, Advance and more) that goes beyond room pricing to give hotels, resorts and casinos a complete picture of their revenue and profitability. Trusted by clients ranging from independent boutique hotels to global chains, we've been named the #1 Revenue Management Software by HotelTechAwards four years running and the #1 Best Place to Work in Hotel Tech in 2025. Backed by GrowthCurve Capital since 2024, we're accelerating our investment in AI — and we're genuinely passionate about the industry we serve. We build products we're proud of, for customers we care about.

What You'll Be Doing

• You'll build and ship full-stack features end-to-end — from understanding the problem with Product, breaking down PRDs into well-scoped work, thinking through edge cases before code is written, all the way through to production monitoring and support.
• You'll experiment with AI-assisted workflows across the development lifecycle — from PRD to tickets to implementation — and push what's possible with AI development tooling in a team that takes this seriously.
• You'll navigate and improve legacy code with care and judgment — understanding what's there, why it exists, and how to move it forward safely without creating downstream risk.
• You'll build new systems from scratch when the problem calls for it, bringing strong systems thinking to every decision about how components fit together, how data flows, and where trade-offs matter.
• You'll develop deep fluency in Duetto's data and the hospitality domain — using that understanding to make better product and technical decisions, not just implement requirements.
• You'll mentor engineers through pairing, code review, and the kind of day-to-day craft conversations that raise the bar for how the whole team works.

What We're Looking For

You may be a good fit if you have:

• Demonstrated seniority in full-stack software engineering with production experience across both backend and frontend layers
• Experience as technical lead on multiple projects that shipped to production
• Experience mentoring engineers and raising team-wide engineering quality
• Hands-on experience with AI development tools and a genuine drive to push what's possible with them
• Strong proficiency in Java
• Frontend capability — not expected to be a specialist, but able to ship frontend work independently
• Experience building and maintaining Data APIs
• Proficiency with SQL and NoSQL databases
• Strong systems thinking — you understand how components fit together, how data flows, and where trade-offs matter
• A background in B2C products with strong UX sensibility, or substantial enterprise software experience

Strong candidates may also have:

• Experience with React, TypeScript, and GraphQL
• Familiarity with AWS
• Experience with data modelling and complex, domain-specific data models
• Enterprise and SaaS software background
• Hospitality technology industry experience

Why Duetto?

• AI-first engineering, for real. This team is actively experimenting with AI-assisted workflows across the entire development lifecycle — you won't just be using Copilot to autocomplete, you'll be pushing what AI-augmented development actually means in practice.
• Work that requires genuine domain depth. The Detect & Explore team builds products that help hoteliers understand and act on complex revenue data — the problems are interesting, the data is rich, and the domain rewards curiosity.
• Staff-level ownership. This is a high-autonomy IC role with real technical influence — you'll shape how the team works, mentor engineers, and make architectural decisions that matter.
• Full-stack scope with a high UX bar. Whether your background is B2C or enterprise, you'll be building products where the quality of the end-user experience is taken seriously — not an afterthought.
• A team that cares about craft. Low ego, high standards, and genuine investment in how engineers grow — the kind of environment where Staff engineers thrive.

The Details

• Location: Remote (Croatia)
• Reporting Line: Director of Engineering

Duetto is an equal opportunity employer. We celebrate diversity and are committed to creating an inclusive environment for all employees. All qualified applicants will receive consideration for employment without regard to race, colour, religion, sex, sexual orientation, gender identity, national origin, disability, veteran status, or any other characteristic protected by applicable law.

Sound like you?

You don't need to have worked in hospitality or checked every box above. If you're a strong full-stack engineer with genuine technical leadership experience, a curiosity for hard data problems, and a drive to work at the frontier of AI-augmented development — we'd love to hear from you.

Engineering Manager

This isn't a coordination role. It's a people-first, delivery-accountable, technically credible leadership position at the heart of one of the most genuinely interesting engineering transformations in hospitality tech. You'll lead a team of 5–10 engineers through a live monolith-to-microservices migration, a frontend re-platform, and the shift to AI-first engineering — where 50–70% of code is already AI-generated and the management job has fundamentally changed as a result.

What Makes Us Different?

Duetto is the hospitality industry's leading revenue management platform, founded in 2012 by former Wynn Resorts executives who knew the industry needed better technology. We built the world's first Revenue & Profit Operating System — a suite of tools (GameChanger, ScoreBoard, BlockBuster, Advance and more) that goes beyond room pricing to give hotels, resorts and casinos a complete picture of their revenue and profitability. Trusted by clients ranging from independent boutique hotels to global chains, we've been named the #1 Revenue Management Software by HotelTechAwards four years running and the #1 Best Place to Work in Hotel Tech in 2025. Backed by GrowthCurve Capital since 2024, we're accelerating our investment in AI — and we're genuinely passionate about the industry we serve. We build products we're proud of, for customers we care about.

What You'll Be Doing

• You'll lead the people: running structured weekly 1:1s focused on growth and wellbeing, owning the full performance cycle, building hiring pipelines from scratch, and creating the psychological safety that lets engineers do their best work — including raising problems early and challenging assumptions, including yours.
• You'll own delivery: sprint planning, backlog refinement, roadmap trade-offs with your Product Manager, and the discipline to surface scope and timeline risks before they become surprises — you're a co-owner of the roadmap, not an executor of someone else's plan.
• You'll drive technical health: partnering with your Tech Lead on architectural direction, championing observability, documentation, and quality standards, and ensuring the team balances feature delivery with the technical investment that makes them faster over time.
• You'll lead through transformation: supporting your team through the monolith-to-microservices migration, the BLAST frontend platform shift, and the move to a generate-and-review engineering model — coaching engineers to evolve their craft as AI changes what great engineering looks like.
• You'll build team culture: designing sustainable on-call rotations, managing capacity with care, developing engineers at every seniority level, and modelling the work-life balance you want your team to have.
• You'll contribute to the wider org: shaping hiring standards, participating in engineering guilds, partnering with Product, Design, QE, and DevOps, and representing your team's perspective in quarterly planning and cross-functional forums.

What We're Looking For

You may be a good fit if you have:

• 3+ years managing engineering teams of 5 or more, with a track record of hiring, developing, and retaining engineers in a high-growth environment
• Experience building hiring pipelines from scratch — role profiles, structured interviews, offer negotiation, and intentional onboarding
• Demonstrated career development impact: you can speak concretely about engineers you've grown from mid to senior, or senior to staff
• Performance management experience including difficult feedback, written reviews, and PIPs
• Strong software engineering background — you've written production code and can hold a genuine conversation about systems design, API design, and data modelling trade-offs
• Working understanding of distributed systems, microservices, event-driven patterns, and CI/CD
• Remote-first leadership experience: you've built real trust and cohesion across timezones without geographic proximity
• A clear point of view on what engineering management means in an AI-first organisation — what changes about coaching, metrics, code review, and quality when 50–70% of code is AI-generated
• Experience working with or alongside teams using AI coding tools (Claude Code, GitHub Copilot, Cursor, or equivalent)

Strong candidates may also have:

• Familiarity with legacy modernisation — monolith decomposition, migration strategies, delivering features while re-platforming underneath
• Experience with revenue management, dynamic pricing, or B2B SaaS for enterprise hospitality
• Hands-on knowledge of our stack: Java/Spring Boot, TypeScript/React, Next.js, GraphQL, MongoDB, AWS
• Exposure to ML or data-intensive systems: real-time analytics, pricing optimisation, low-latency data processing

Why Duetto?

• You'll be managing at the frontier of AI-first engineering. With 50–70% of code AI-generated and custom agents and agentic workflows already in production, this is a rare opportunity to define what great engineering management looks like when code generation is no longer the bottleneck.
• The transformation is real and consequential. Live monolith decomposition, a frontend re-platform, and an AI-first shift — all simultaneously. These are the moments that define engineering careers and management reputations.
• Clear growth path. EM → Senior EM → Director of Engineering. Duetto promotes from within and takes management seriously as a discipline, not a consolation prize for engineers who stopped coding.
• The work matters. Your teams build systems that process real-time pricing decisions for global hotel brands. It's visible, high-stakes, and genuinely interesting.
• Benefits worth having. Equity participation, comprehensive health, dental and vision coverage, home office stipend, generous PTO, and a learning and development budget.

The Details

• Location: Croatia
• Work model: Remote, distributed across EMEA and Americas timezones
• Reports to: Director of Engineering / VP of Engineering
• Direct reports: 5–10 engineers (1–2 teams)

Duetto is an equal opportunity employer. We celebrate diversity and are committed to creating an inclusive environment for all employees. All qualified applicants will receive consideration for employment without regard to race, colour, religion, sex, sexual orientation, gender identity, national origin, disability, veteran status, or any other characteristic protected by applicable law.

Sound like you?

You don't need to have done everything on this list. If you're a people-first leader who's technically credible, genuinely curious about AI-augmented engineering, and energised by the idea of leading teams through real transformation — we'd love to hear from you.

#LI-REMOTE

Senior Fullstack Engineer

If you love building software that actually matters — and you're energised by the idea of shipping production-grade features across the full stack while working in a team where AI is a genuine daily collaborator, not a buzzword — this role is for you. You'll own end-to-end delivery on Duetto's core revenue platform, drive a major migration from monolith to microservices, and help shape how the team engineers at scale.

What Makes Us Different?

Duetto is the hospitality industry's leading revenue management platform, founded in 2012 by former Wynn Resorts executives who knew the industry needed better technology. We built the world's first Revenue & Profit Operating System — a suite of tools (GameChanger, ScoreBoard, BlockBuster, Advance and more) that goes beyond room pricing to give hotels, resorts and casinos a complete picture of their revenue and profitability.

Backed by GrowthCurve Capital since 2024, we're accelerating our investment in AI — and we're genuinely passionate about the industry we serve. We build products we're proud of, for customers we care about.

What You'll Be Doing

• You'll own full-stack feature delivery end-to-end — from requirements through to production — across Java/Spring Boot microservices and TypeScript/React frontends, including monitoring and troubleshooting in live environments.
• You'll make independent architectural decisions and convert prototypes into scalable, maintainable production systems, collaborating closely with Product, Design, and Engineering to hold a high bar for end-user quality.
• You'll drive the migration of our legacy monolith, applying Domain-Driven Design principles, event-driven architecture patterns, and structured decomposition strategies to modernise software at scale.
• You'll champion test quality by writing automated end-to-end tests in Cypress or Playwright and embedding data-driven testing practices across the team.
• You'll mentor peers on prompt engineering, AI-assisted development, and code review — operating confidently in a generate-and-review model where 50–70% of code is AI-generated.
• You'll contribute to and improve AI-augmented engineering workflows, building and refining custom skills, agents, and agentic pipelines that accelerate the whole team's delivery velocity.

What We're Looking For

You may be a good fit if you have:

• 4–6 years of full-stack engineering experience with production depth across both backend and frontend
• Strong proficiency in Java and Spring Boot for enterprise backend development
• Strong proficiency in TypeScript and React for modern web applications
• Experience building and maintaining GraphQL APIs
• Solid working knowledge of SQL and NoSQL databases, particularly MongoDB
• Hands-on experience with end-to-end testing frameworks — Cypress or Playwright
• A working understanding of microservices architecture and event-driven integration patterns
• Demonstrated experience with Claude Code CLI or a comparable AI code generation tool — you're comfortable in a generate-and-review workflow, not just curious about it

Strong candidates may also have:

• Experience in or exposure to the hospitality technology sector
• A background in legacy modernisation — monolith decomposition, migration planning, or similar
• Familiarity with Domain-Driven Design (DDD) in an enterprise context
• Experience with AI code review tools such as CodeRabbit or Augment
• Working knowledge of AWS, Kubernetes, and CI/CD pipeline management

Why Duetto?

• AI isn't a side project here — it's how we work. With 50–70% of code AI-generated and a team actively building custom agents and agentic pipelines, you'll be operating at the frontier of how software gets built.
• Real architectural ownership. This is a high-autonomy IC role — you'll make independent technical decisions that shape the platform, not just implement tickets.
• Work that ships. We move fast, hold a high bar, and care deeply about what we put in front of customers. If you want to see your work in production, you will.
• A mission worth caring about. Hospitality is a people industry, and we help the people running it do their jobs better. That's something to feel good about.
• Fully remote from Split, Croatia, with a global team that takes collaboration seriously.

The Details

• Location: Split, Croatia
• Work model: Remote
