About Flight Experience Team

We own the three travel essentials that give customers total peace of mind: securing bags and seats, delivering a frictionless check-in experience, and providing an instant safety net when plans go sideways. Operating in small, AI-native engineering teams, we build and own end-to-end features like automated check-in systems, live terminal tracking, and instant disruption refunds—shipping fast, iterating in real time, and letting data keep us honest.

What you will do

• Drive AI-powered innovation across our core stack by supporting the build of highly efficient, real-time solutions for disruption handling, automated check-in, baggage, and seating.
• Ensure engineering excellence by taking complete ownership of holistic solutions, writing maintainable code, and fostering robust unit, integration, and manual testing practices.
• Think beyond the codebase by leveraging product and business metrics to uncover real traveler needs and shape high-impact technical features through shared insights.
• Collaborate for success in a highly supportive, cross-functional environment alongside Product Managers, UX Designers, Data experts, and neighboring engineering teams.
• Ship early and iterate fast to continually refine live services, bringing ideas to life and moving from initial concept to production deployment with trust and autonomy.

What you will need

• A proven track record of accelerating development using AI-native tools like Cursor or Claude Code to streamline workflow cycles, nurture efficient processes, and maximize daily R&D output.
• You have advanced knowledge of Python development, writing clean, stable, and maintainable production code, with working familiarity with Golang as a welcome plus.

• You bring a proven track record of owning projects end-to-end from inception to production, sharing responsibility for safe deployments and nurturing cloud infrastructure reliability.
