Senior Python Engineer

Senior Python Engineer — Travel & Expense Platform Company: Trip. Gain

• Location: Bangalore
• Experience: 5–8 years About the work We build corporate travel and expense software, plus a booking platform used by travel agencies. You'd be working on services that search and book flights, hotels and ground travel, process expense receipts and invoices, integrate with airline and supplier systems, and increasingly, on AI assistants that do this work on a user's behalf. You'll own features end to end — from design through production — rather than picking up pre-specified tickets.

What we're looking for

Python backend depth (5+ years) Strong Python, ideally with FastAPI; async programming you genuinely understand, not just async def on everything You've designed and maintained APIs that other teams or customers depend on Databases Solid relational database skills — schema design, query performance, and a careful hand with production data and schema changes Integration Real experience wiring up third-party APIs that are inconsistent, poorly documented or legacy, and turning them into something clean your own code can rely on Background jobs, caching, queues, webhooks AI / LLM work You've shipped an LLM-backed feature to production with real users — not a prototype You understand where these models are unreliable and how to design around it: validation, fallbacks, confidence handling, cost and latency control Craft You test what matters, document what you build, and verify your own work before calling it done You're comfortable with AI coding tools and review their output as carefully as a colleague's Nice to have Travel or fintech domain experience Multi-tenant SaaS Analytics or data-heavy systems Enough frontend to build an internal admin screen Vector search / RAG, agent frameworks, MCP How we work Correctness matters more to us than speed or cost — we don't trade accuracy for a faster response We write and speak in plain language, in code, UI and docs alike Small team, high ownership, short path from idea to production
