Senior Software Engineer, Backend - Lodging

Engine is the all-in-one travel and spend management platform trusted by 38K+ businesses and groups representing 1.8M+ travelers. We're the retailer and the rails of business travel, the fastest-growing company in travel tech, built on a decade of proprietary technology, supply, and pricing no one else can replicate. Other travel and AI companies run on our infrastructure to book real trips, hold rates, and move payments, without building any of it themselves. We built it, AI-forward at every layer, from how travelers book to how the rails run.

That work has earned recognition as one of Fast Company's Best Workplaces for Innovators (2025), TravelTech's Reservation Platform of the Year (2026), and one of Built In's Best Places to Work (2020–2026).

We're looking for bold, ambitious people to help redefine how businesses manage and experience travel. Working here, you can expect exponential growth, an ambitious pace, full ownership, and high-caliber colleagues who push you to do the best work of your career. Every hire raises the bar. 

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

The Lodging team owns the entire backend behind Engine's highest-demand vertical: Search, Integrations, and Bookings. Three systems, one team, one set of priorities. Node.js powers Search and Integrations; Kotlin runs Bookings.

The business is scaling fast. Our Partner API is live and large external companies are integrating directly with Engine — which means moving business logic out of the frontend and building clean backend wrappers our partners can rely on. Work varies week to week: a pricing team request one week, a new supplier integration the next, a tricky data bug after that. High volume, high stakes, real ownership.

• →Contribute across all three backend systems: Search, Integrations, and Bookings
• →Build and maintain business logic for the Partner API integration layer
• →Handle cross-team requests from Pricing, FinTech, Content, and Data — clarifying scope, driving to solutions
• →Partner closely with the PM, frontend lodging team, and supplier integrations lead
• →Own projects end to end: surface blockers, keep things moving, deliver

• Hands-on experience with AI-assisted development (Claude, Cursor, or equivalent) — we're expanding AI use across engineering
• Cloud experience (AWS preferred)
• Strong SQL and relational database fundamentals
• A self-directed working style — you don't need daily direction; you find the work and drive it forward
• Comfort with ambiguity — cross-team requests rarely arrive neatly scoped, and you know how to ask the right questions
• Adaptable to shifting priorities — lodging moves fast, and plans change

• Node.js or Kotlin experience (either is a strong plus given the stack)
