Senior Software Engineer, Backend - Lodging

About Engine At Engine, we’re transforming business travel into something personalized, rewarding, and simple. For too long, managing travel and spend has been overwhelming and fragmented — we’re here to change that. We believe the future of travel should be seamless and powered by technology that delights customers at every step. That’s why we’re building a platform that brings together corporate travel, a powerful charge card, and modern spend management in one place. To make this vision real, we’re looking for exceptional, mission-driven people to help redefine how businesses manage and experience travel. More than 30,000 companies already rely on Engine to support over 1 million travelers and billions in annual bookings each year. Cash flow positive with rapid growth, we pair exclusive Engine-only rates, industry-leading rewards, and intelligent automation to help businesses save money while delivering world-class personalization and convenience. Backed by Telescope Partners, Blackstone, and Permira, Engine has been recognized as one of the fastest-growing travel and fintech platforms in North America, with honors including the Deloitte Fast 500 and Built In’s Best Places to Work. The Role 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. What You'll Do 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 What We're Looking For Required: 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 Nice to Have: Node.js or Kotlin experience (either is a strong plus given the stack) This is a contractor role for candidates based in Latin America only.
