Senior Software Engineer - Travel Management

About Engine

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 Role

The Travel Management team owns the systems that make Engine work for enterprise customers — travel policies, travel controls, account hierarchy, roles and permissions, and granular policies across lodging, flights, and cars. This is where scale meets configurability, and where the platform earns the trust of the largest companies we serve.

We're looking for a Senior Software Engineer who can design distributed backend systems, make tough calls with incomplete information, and drive scalable, enterprise-grade solutions across a highly cross-functional environment. You'll be a heavy backend contributor, working on greenfield architecture and re-architecting existing components as we unlock the next stage of the platform.

What You'll Do

Re-architect account hierarchy — migrating from single-user-per-business assumptions to a scalable model that supports complex parent-child business relationships

Build out dynamic travel policies that scale across lodging, flights, and cars for enterprise customers

Evaluate what stays in the monolith vs. moves to microservices — and make the call

Collaborate closely with business stakeholders on negotiations and tough product calls

Partner with frontend engineers on the team to ship features end-to-end

What We're Looking For

Required:

Strong backend engineering fundamentals in Java / Kotlin

Solid relational database experience (Postgres, MySQL) and distributed systems knowledge

AWS architecture experience

Conviction with rationale — you make decisions with incomplete information, own them, and move forward

Highly cross-functional — you'll interface directly with business partners on negotiations and product decisions

Comfortable operating in ambiguity and negotiating outcomes across engineering and business

Insist on high standards — for your code, your systems, and your team

Nice to Have:

Ruby on Rails experience (some of our services are on Rails)

Prior experience building multi-tenant enterprise systems, permissions frameworks, or policy engines
