Exadel Culture

We lead with trust, respect, and purpose. We believe in open dialogue, creative freedom, and mentorship that helps you grow, lead, and make a real difference. Ours is a culture where ideas are challenged, voices are heard, and your impact matters.

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.

*As part of our standard hiring process, we would like to inform you that a background check may be conducted at the final stage of recruitment through our third-party provider, Checkr.
*Please note that Cast AI does not provide any form of visa sponsorship/work permit.

About Us:  

Delasport is where technology meets the excitement of sports and gaming! As a leading powerhouse in iGaming software, we provide everything from sports betting to online casinos and player account management. Our platform is designed to make every player feel like the star of the show, with personalized experience and cutting-edge technology at its heart.    

Since 2010, we've made a significant impact in industry, earning awards and expanding our global presence. With offices in Bulgaria, Ukraine, and Malta, our team of over 500 experts is constantly driving innovation and striving for excellence.  

About the Role 

We're hiring a Team Lead for one of the most consequential engineering teams at Delasport - the team that owns KYC, AML, anti-fraud, and regulatory compliance across the platform. 

These aren't peripheral services. They're what makes it legally possible for our operators to take a bet in every market we're licensed in. Every player who signs up, every withdrawal, every suspicious pattern, every regulator report - it flows through systems your team owns. When a new jurisdiction comes online, your team is on the critical path. 

If you want a leadership role where the work is technically real, the stakes are visible, and the autonomy is genuine - read on.

This role is based in Sofia, Bulgaria and we welcome candidates who are open to relocating (relocation support provided). 

What Your Team Owns 

You'll lead a team of 5 full-stack developers and 2 QAs responsible for: 

• KYC - identity verification pipelines, document checks, and third-party provider integrations 
• AML - transaction monitoring, sanctions and PEP screening, suspicious-activity detection 
• Anti-Fraud - behavioural analysis and fraud-pattern detection across player activity 
• Regulatory Compliance - jurisdiction-specific rules, reporting obligations, and operator configurations 

The footprint is a mix of synchronous APIs, scheduled jobs, and real-time stream consumers processing events off Kafka and RabbitMQ. 

What You'll Actually Work On  

• Shaping the future stack. Today the team works across PHP/Laravel, Python, and TypeScript/Vue. All new services will be written in Node.js, and you'll be a key voice in shaping how that evolution unfolds - patterns, shared libraries, deployment standards. 
• Driving technical excellence. Setting and raising the bar on performance, reliability, and operational maturity across the team's services. 
• Real ownership of production. The team owns its services end to end - design, build, ship, observe, fix. You set the standard for how that ownership is exercised. 
• Growing the team. Seniors ready to push toward staff-level work; mids ready to grow into seniors. Your impact on them will be one of the most rewarding parts of this role. 

What You’ll Do 

• Lead the team. Set technical direction, code-quality bar, and architectural standards. Run code reviews that teach. Develop the engineers under you. 
• Stay hands-on. This is not a pure people-management role. You'll write code, design systems, and pair on hard problems. 
• Architect for the real world. Design services that handle real-time event streams reliably, fail safely under regulatory scrutiny, and integrate cleanly with the third-party providers we depend on. 
• Drive the technical roadmap. Make and defend the calls on what to refactor, what to rewrite, and where to invest the team's time. 
• Partner across the org. Work closely with Product, DevOps, Data, and the Compliance/Legal side of the business - the last of which is unusual for an engineering role and one of the more interesting parts of the job. 

Employees may be required to participate in an on-call rotation, ensuring availability outside regular working hours to respond to urgent issues as needed as per the On call policy. 

Why This Role Is Different 

• High business impact. When KYC breaks, players can't deposit. When AML breaks, we have a regulatory problem. The work matters and people know it. 
• Polyglot by design, not by accident. PHP, Python, TypeScript today; Node.js for everything new. If you're tired of being pigeonholed in one language, this team doesn't do that. 
• Genuine ownership. Your team owns its services end to end. No throwing things over the wall. 
• Regulated-domain depth. You'll learn how iGaming compliance actually works at the engineering level -  a specialisation that's genuinely valuable and surprisingly rare on the market. 

Who You Are  

• Experience: 7+ years building backend systems in PHP, including 2+ years leading a team or operating as a senior technical lead. 
• Core technical strength: 
• Strong PHP and OOP fundamentals - design patterns, clean architecture, testability. 
• Production experience with Laravel (or strong Symfony experience and the willingness to ramp on Laravel). 
• Comfortable working with event-driven systems - Kafka, RabbitMQ, or equivalent. You've built and operated consumers, not just published a message once. 
• Solid grasp of relational databases (MySQL/PostgreSQL) - schema design, query performance, the things that bite at scale.

• Leadership: You lead by setting direction and raising the bar of those around you, not by managing tickets. Strong written and spoken English. 
• Mindset: Pragmatic, bias toward shipping, comfortable with ambiguity, genuinely interested in the business problem and not just the technical one. 

Nice to Have 

• Experience in iGaming, fintech, or any regulated domain (banking, payments, healthcare). 
• Hands-on experience with KYC/AML/fraud-prevention systems or vendor integrations. 
• Working knowledge of Python and/or Node.js. 
• Exposure to TypeScript/Vue or another modern frontend stack.

About Us: 

Delasport is where technology meets the excitement of sports and gaming! As a leading powerhouse in iGaming software, we provide everything from sports betting to online casinos and player account management. Our platform is designed to make every player feel like the star of the show, with personalized experience and cutting-edge technology at its heart.   

Since 2010, we've made a significant impact in industry, earning awards and expanding our global presence. With offices in Bulgaria, Ukraine, and Malta, our team of over 500 experts is constantly driving innovation and striving for excellence. 

About the Team:

The Product Launch team is built for people who don’t just maintain systems but create them. We take products from zero to hero, and scale them until they’re strong enough to be handed over to core teams. No legacy constraints. No endless support cycles. Just greenfield builds, modern tech, and real ownership from day one. 

We move fast, think lean, and execute with focus, one product at a time, full commitment, full impact. Every sprint matter, every decision ship value. This is not a support team. It’s a build-from-scratch engine for products that matter, because every hero needs a superhero.

What You’ll Do:

• Technical Quality Ownership - Set and enforce technical standards for code quality, testing practices, deployment procedures, and observability across all teams. Ensure deliverables consistently meet company and industry standards. 

• Security & Compliance - Champion security best practices in application design and delivery. Drive secure coding standards, dependency management, and vulnerability remediation across the development lifecycle. 

• Technology Decisions - Drive and consult on technology choices in collaboration with the Architect and engineering teams. Evaluate new tools, frameworks, and patterns with a clear focus on efficiency, maintainability, and long-term sustainability. 

• Architecture & Design Guidance - Review and guide system designs, API contracts, data models, and integration patterns. Ensure business requirements are implemented following sound architectural principles and established standards. 

• Hands-On Engineering - Stay deeply hands-on with production code. Lead by example in modern Java (21/25), Spring Boot 3/4, PHP, Laravel, NodeJS, Kafka Streams, and cloud-native microservices. Conduct in-depth code reviews and contribute to critical path development. 

• Observability & Operational Excellence - Define and drive observability standards (metrics, logging, tracing, alerting) to ensure production systems are transparent, diagnosable, and reliable. 

• Technology Adoption - Drive the adoption of new technologies and practices across teams. Build proof-of-concepts, define migration paths, and ensure smooth rollouts with minimal disruption. 

• Cross-Team Collaboration - Act as the technical mediator between Java teams, Team Leads, the Architect, and business stakeholders. Translate business requirements into sound technical guidance and ensure alignment across all parties. 

• Knowledge Sharing - Foster a culture of technical excellence through design reviews, tech talks, documentation, and hands-on mentoring of senior engineers. 

Employees may be required to participate in an on-call rotation, ensuring availability outside regular working hours to respond to urgent issues as needed as per the On call policy.

Who You Are:

Experience: 7+ years of hands-on backend development with strong expertise, including 2+ years in a technical leadership capacity (Tech Lead, Principal Engineer, or equivalent). 

Technical Expertise: 

• Deep knowledge of Java (21+), PHP or NodeJS concurrency, JVM internals, and performance characteristics 
• Strong experience with building production-grade microservices 
• Strong expertise with Kafka and Kafka Streams — event-driven architectures, stream processing, schema evolution, and exactly-once semantics 
• Solid understanding of REST API design principles and synchronous integration patterns 
• Hands-on experience with Kubernetes, GitOps (ArgoCD, Kustomize), and container orchestration 
• Experience defining and implementing observability strategies (metrics, distributed tracing, structured logging, alerting) 
• Strong understanding of application security practices, secure coding, and dependency management 
• Solid database knowledge: relational and document databases, data modeling, and performance tuning 

Soft Skills: Excellent communicator who can translate between technical and business language. Comfortable presenting ideas, challenging decisions constructively, and building consensus across teams. 

Collaboration: Proven ability to work effectively with Architects, Team Leads, Product, and DevOps in a cross-functional environment. 

Mindset: Ownership-driven, pragmatic, and passionate about engineering excellence. You care as much about maintainability and operational quality as you do about shipping features. 

Nice to Have: 

• Experience in iGaming, Sportsbook, or real-time transaction-heavy systems 
• CDC architectures (Debezium) 
• Redis or distributed caching strategies 
• Performance tuning and benchmarking (JMH, async-profiler, JFR) 
• Architecture patterns such as DDD, CQRS, or Event Sourcing 
• Contributions to open-source projects 

What We Offer: 

We’re not just about work,  we are about creating a great place to grow, connect, and enjoy the journey. Here’s what you can expect when you join us:

• Competitive Salary Package: We value your skills, dedication, and contributions
• Time Off: Enjoy 21+ days of annual paid leave so you can rest, recharge, and come back inspired
