We are hiring for Staff Software Engineers, Backend, on multiple teams across our organization. Your application will be considered for any open positions that are a fit. Below the details of the role there is a short description of each team with an opening.

Your Mission

As a Staff Software Engineer at Engine, you’ll play a vital role in an environment where innovation meets collaboration. Here’s what you’ll take charge of:

• Design and Implement: Craft innovative software systems and APIs that contribute to the success of Engine’s mission, focusing on scalability, security, and performance.
• Collaboration: Collaborate with cross-functional teams, including Product and Data Science, to unlock new opportunities and deliver seamless experiences for our customers.
• Leadership: Mentor mid-to-senior level engineers, and lead efforts to ensure the quality, scalability, and robustness of our software.
• Ownership: Lead key initiatives that improve efficiency, enhance system performance, and drive customer satisfaction.

What You’ll Bring to Engine

We’re looking for someone who’s ready to make an impact and grow alongside us:

• Experience: 8+ years of hands-on experience in designing, implementing, and maintaining highly available and high-performing distributed systems. You have a proven track record of building public-facing (consumer-grade) APIs and managing the complexities of versioning, deprecation, and consumption-based rate limiting. Experience with Node.js, TypeScript, Kotlin (or similar modern backend languages), and AWS is a plus.
• Skills: You’re a problem-solver with a strong grasp of software design principles, scalability, and system architecture. You thrive in fast-paced, innovative environments and prioritize Domain-Driven Design.
• Mindset: You’re ready to roll up your sleeves, collaborate, and deliver results that matter.

Pricing Team

The Pricing team builds the real-time systems that determine what every customer pays across our travel marketplace. We design and operate auction-based pricing engines, models informed by Machine Learning, and customer segmentation strategies — all running at scale across Lodging, Car Rentals, and Flights. Our work directly impacts conversion, revenue, and competitiveness, and the results are immediately measurable

IDM Team

The Identity Management team owns authentication and authorization for Hotel Engine's customers. We operate the Auth0 tenant, shape the login experience, and partner with enterprise customers to deliver secure, reliable identity integrations — so every traveler, admin, and partner can access the right things, at the right time, with confidence.

Lodging Team

The Lodging team owns the end-to-end traveler journey, from the first search through checkout and beyond. We build beautiful, intuitive interfaces that mask the immense complexity of global travel logistics, transforming intricate inventory data into a world-class booking experience. By managing the systems that support the entire booking life cycle, we ensure our customers have the seamless care and reliability they need at every step of their trip.

Your Mission

You will be the senior technical leader for Groups Shopping at Engine — the team that owns how group travel organizers discover and select hotels. We are building a world class travel shopping experience, and improving our property-ranking system to better understand what an organizer is looking for. You will help drive that work, set the technical bar, and make sure we ship with high quality.

This role exists to push three things forward:

1. Property ranking that earns its weight. Hotel discovery is the highest-leverage moment in the group booking funnel and historically the place where ranking has been least intelligent. Optimizing how we score, sort, and present properties — using a mix of behavioral data, response signals, fit signals, and LLM reasoning — is core to what this team is being asked to do.
2. Step-change scale. Groups is heading toward an order-of-magnitude increase in volume. The systems we build this year have to deliver conversion gains that compound, hold up under multiples of today's load, and not get undone by the operational drag of fast growth.
3. AI inside the product. The most interesting UX advances in Groups travel right now come from putting AI directly in the organizer's hands — embedded assistance that helps them search, compare, and decide without leaving the flow. You will help define and ship the surfaces where this happens, including the seam between the product and the AI tools that drive it

What You'll Own

• Architecture for Groups Shopping. The hotel discovery, scoring, and selection surfaces — and the integration points where ranking, search, and AI in the product come together.
• The technical bar. You are the gate for quality on this team. Code review on hard PRs, design review on every meaningful change, "is this the right abstraction" calls before they become permanent.
• AI in the workflow. Both the agentic coding posture inside the team (we expect every engineer to be using Claude Code, Cursor, or equivalent every day) and the agentic product surfaces — tool definitions for AI surfaces in the product, prompt and skill design where needed, scoping which problems the LLM should and shouldn't own.
• AWS and CI/CD. Our backend runs on AWS — services, queues, data pipelines, ECS/Lambda where appropriate. You will own non-trivial infrastructure decisions and be the person who makes our deploy and CI story sharper.
• Mentorship and unblocking. Pairing with senior engineers, running design reviews, writing the docs that make the next person's job easier, being the named contact when another team needs a Groups Shopping perspective.

What We're Looking For

Must-haves

• TypeScript and Node in production at scale. We are open to other modern backend languages on your résumé, but our stack is TS/Node and you should be ready to be productive in it within weeks.
• AI-first as a daily practice, not a talking point. You are actively using agentic coding tools (Claude Code, Cursor) and you have a point of view on where they help, where they hurt, and how to set the team's defaults. We will ask you to walk us through a real example of how you use them.
• Deep AWS and CI/CD. Not "I've used Lambda before." Closer to: you can debug a misbehaving ECS service in production, you have opinions on IaC, and you can sharpen a slow CI pipeline.
• Cross-functional, multi-level communication. You can write a one-page tech doc that a PM can review, run a design discussion with three other staff engineers, and walk a senior leader through a trade-off without a slide deck.
• Comfort leading and running a team. Not as a manager — as the most senior engineer the team leans on for direction, sequencing, and quality. You've done this before and it's a part of the job you actually like.

Nice-to-haves

• Deep TypeScript / Node — internals, performance, type-system fluency.
• Product experience — you can wear a PM hat for an afternoon and think from the customer's seat.
• Travel, hospitality, marketplace background.
• React Native familiarity

Your Mission

As a Principal Engineer at Engine, you will play a key role in shaping the technical direction of our platform as we transition from monolithic applications to a distributed architecture. You’ll work across teams to define service boundaries, ensure system coherence, and guide the evolution of our platform while maintaining scalability, performance, and maintainability.

What You'll Do

• Define and champion architectural best practices, helping teams design services that are modular, maintainable, and aligned with long-term business needs.
• Lead the transition from monoliths to distributed systems, ensuring scalability, resilience, and long-term maintainability.
• Shape the technical roadmap, working with engineering leaders to drive key decisions around service design, data flow, and system interactions.
• Dive deep into technical challenges, collaborating with engineers to solve complex problems and ensure high-quality implementations.
• Mentor and influence engineers, fostering a culture of strong engineering fundamentals, service ownership, and thoughtful system design.
• Collaborate across teams to ensure our architecture supports business needs without unnecessary complexity.

What You’ll Bring to Engine

We’re looking for someone who brings deep technical expertise, strategic thinking, and strong influence skills to help us scale our platform.

• 12+ years of experience designing and evolving high-scale distributed systems.
• Strong architectural leadership—you have driven major technical initiatives across multiple teams and influenced engineering direction at an organizational level.
• Expertise in designing modular, loosely coupled systems, with experience breaking down monolithic applications into well-structured services.
• Proven ability to guide teams through complex technical challenges, making high-impact decisions in ambiguous environments.
• Mastery of cloud environments and services (AWS preferred), including best practices for building reliable, scalable systems.
• Experience designing APIs and defining clear service boundaries, ensuring interoperability and maintainability.
• Deep understanding of distributed system patterns, including event-driven architectures, data consistency models, and service communication strategies (REST, gRPC, messaging).
• Strong problem-solving skills and a pragmatic approach—you know when to apply best practices versus when to adapt to practical constraints.
• Excellent collaboration and communication skills, with experience influencing engineering teams and leadership without direct authority.

We accept applications for this role on an ongoing basis. We review applications as they are received and encourage interested candidates to apply early.

As Staff Engineer on the Control Plane / Core team, you're one of a handful of people who set the technical direction for how every engineering team at Engine builds and ships. You won't be embedded in a single vertical — you're working on the substrate underneath all of them.

You'll be hands-on with

• AWS control plane— multi-account architecture, account vending, VPC networking, organizational guardrails, IAM boundaries.
• CI/CD platform— template pipelines, shared GitHub Actions/workflows, org-level policies, secret distribution. You moderate what's shared; teams contribute upward.
• Terraform execution— Terraform Cloud workspaces, module registry, our internal modules, the tooling that lets a feature team stand up a namespace and start shipping in hours, not weeks.
• Networking & security— Cloudflare (WAF, DNS, WARP, page rules), core network topology, certificate management.
• Vendor integrations— Datadog, JFrog, Terraform Cloud, GitHub OIDC — the connective tissue between vendors and our accounts.
• Cost observability— tooling and dashboards that give teams visibility into what they own and spend.

You'll also be a force multiplier for the embedded engineers: the patterns, modules, and primitives you build are what they hand to feature teams. When something embedded engineers keep solving locally needs to become a paved road, that's your work.

What You'll Do

• Lead the technical evolution of the control plane — not just keep it running, but decide where it goes next.
• Design and ship platform primitives (Terraform modules, pipeline templates, account/networking patterns) that feature teams adopt because they're better than the alternative — not because they're mandated.
• Partner with embedded infra engineers to identify recurring friction across verticals and turn it into self-serve capability.
• Own the boring-but-critical work: AWS Organization hygiene, CI/CD reliability, vendor contracts and integration health, incident response on shared infrastructure.
• Mentor across the discipline. We hold infra standups twice a week — that's where you'll teach, learn, and stay aligned with the embedded engineers.
• Reduce the SDLC step-function count. Every new approval gate, every "ask infra first" workflow is a tax — your job is to lower it.

What We're Looking For

Required

• 8+ years building and operating production cloud infrastructure, with deep AWS expertise (multi-account, networking, IAM, security boundaries).
• Expert-level Terraform — you've designed reusable modules, run TFC at scale, and have opinions about state, drift, and execution patterns.
• Strong CI/CD background — GitHub Actions, reusable workflows, OIDC, secret management.
• Experience with platform engineering: shipping internal tools and abstractions that other engineers actually want to use.
• A bias toward enabling teams over gatekeeping. You'd rather build the paved road than approve the off-road permits.

Strongly preferred

• Cloudflare (WAF, DNS, zero-trust/WARP) at production scale.
• Datadog, JFrog, or comparable vendor integration experience.
• Background in cost observability or FinOps tooling.
• History of working in or alongside embedded/platform models — you understand the difference between a platform team and a ticket queue.
