Role

We are looking for a Senior Software Engineer to join our Content Gateway development team. A team that runs high-volume search and booking services: millions of searches a day, 50k bookings a day, 100-500ms latency budgets, and availability targets where minutes of downtime are measured in real money and stranded travellers.

Responsibilities

• Design and operate services in the booking and connectivity path - the part of the system where correctness and availability matter most.

• Make architecture decisions with real trade-offs: consistency vs. latency, caching vs. correctness, retry vs. duplicate booking.

• Debug production issues end to end - through your service, the runtime, the network, and third-party airline APIs that fail in creative ways.

• Raise the bar for the engineers around you through design reviews and code reviews that go deeper than style comments.

• Shape our internal platform engineering tooling - context engineering, MCP servers, and the AI-assisted development infrastructure the whole engineering org builds on.

Requirements

We deliberately don't screen on frameworks or tools. We screen on whether you understand how systems actually work. Concretely:

• System design in practice, not theory. You've designed and run distributed systems under real load, and you can explain the decisions you made and the ones you'd take back.

• You know what your code compiles down to. Comfortable reasoning about memory, garbage collection, threads vs. async, and what the OS is doing underneath - because that's where the hard production bugs live.

• You've operated what you've built. On-call experience, incident debugging, reading metrics and traces under pressure. You know the difference between a system that works and a system that keeps working.

• You go one level deeper than you need to. When something is slow, you don't stop at "the database is slow" - you find out why.

• A can-do attitude and fluency in AI-assisted development. You treat tools like Claude Code and agentic workflows as force multipliers, not threats - and you know their failure modes well enough to review AI-generated code with the same rigor as human-written code.

• 4+ years building software, with meaningful time on high-traffic backend systems.

Our stack

Mostly Go and .NET on GCP and OpenStack, with Redis, PostgreSQL, and Elasticsearch. If you've worked in Java, C++, Rust, or anything comparable and understand the fundamentals above, you'll be productive here quickly. We care that you can learn our stack in weeks - most strong engineers can - not that you already list it.

What it Takes to Succeed Here

Ambition and dedication to making a difference and changing the way people travel; where we always play to each other's strengths in a high-performing team reaching for our common goal. We hold ourselves to the highest expectations, move with a sense of urgency, hold ourselves accountable, and win by staying true to what we believe in.

What We Offer

We offer an opportunity to work with a young, dynamic, and growing team composed of high-caliber professionals. We value professionalism and promote a culture where individuals are encouraged to do more and be more. If you feel you share our passion for excellence and growth, then look no further. We have an ambitious mission, and we need a world-class team to make it a reality. Upgrade to a First-Class team.

How we interview

We tell you this upfront because it tells you what we value:

1. A practical coding/ debugging session - working code, realistic problem, done together. No leetcode puzzles, no take-home you could outsource.

2. A live system design session - a problem from our domain, whiteboard-style, trade-offs out loud.

3. A conversation about a system you built - we'll go deep. Expect follow-up questions until we reach the edge of what you actually did.

How to apply ?

Skip the cover letter. Instead, send your CV with a short answer (10 - 15 sentences, plain text) to one question: describe the hardest production problem you personally debugged - what the symptom was, how you narrowed it down, and what the root cause turned out to be. Specifics matter more than polish.
