Come outpace the ordinary and build the future of travel with us.

We're looking for a Senior Software Engineer who combines strong system design instincts with the communication skills to work across technical and non-technical stakeholders. This is a backend-heavy role with a lot of autonomy, real technical challenge, and a team that runs on AI.

What You'll Do

• Drive the design and implementation of greenfield services, replacing legacy code with modern microservices, strong test coverage, and production-grade observability
• Collaborate closely with Product Managers and other Engineering teams to translate requirements into engineering solutions
• Use AI tools (Claude and/or Cursor) as your primary development environment
• Drive projects independently: own your work, surface blockers, keep things moving

What We're Looking For

Required:

• AI fluency — you're comfortable using Claude, Cursor, or similar tools as your main coding interface; you don't just use them occasionally
• Strong system design skills — you can walk through architectural decisions you've made, explain tradeoffs, and think at the infrastructure level
• Proven delivery — you've shipped complex systems, not just features; you can speak to the weight and scope of what you've built
• Self-directed working style — you don't need daily direction; you identify what needs to happen and drive it
• Comfortable handling ambiguity — cross-team requests don't always come in neatly scoped; you ask the right questions and figure it out
• Adaptable to shifting priorities — lodging is the highest-demand vertical at Engine; plans change
• Excellent communication — you can explain technical problems clearly to non-technical stakeholders like accountants and business ops teams
