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 Billing team is the financial backbone of Engine. Every booking, every card transaction, every direct bill goes through us. We support Engine's main fintech products, and we're in the middle of a major re-architecture, replacing 8-year-old legacy infrastructure with modern, scalable microservices built right.

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 a greenfield billing service, replacing legacy code with modern microservices, strong test coverage, and production-grade observability
• Enable other product teams by building and maintaining billing infrastructure they depend on
• Triage and resolve billing support tickets, including escalation to the payments team when needed
• Collaborate closely with the Accounts Receivable team to translate accounting requirements into engineering solutions
• Use AI tools (Claude and/or Cursor) as your primary development environment

What We're Looking For

Required:

• Strong system design skills — you can walk through architectural decisions you've made, explain tradeoffs, and think at the infrastructure level
• Excellent communication — you can explain technical problems clearly to non-technical stakeholders like accountants and business ops teams
• AI fluency — you're comfortable using Claude, Cursor, or similar tools as your main coding interface; you don't just use them occasionally
• Proven delivery — you've shipped complex systems, not just features; you can speak to the weight and scope of what you've built

Nice to Have:

• Experience in FinTech, payments, fraud, or billing systems — adjacent domains like fraud prevention or payment logistics count
• Java or Kotlin background (most of our services are Java/Kotlin; not a hard requirement with AI in the loop)
• Terraform, Datadog, or Splunk experience

This is a contractor role for candidates based in Latin America. Applications for this role will be accepted through July 30th until the role is filled. We encourage you to apply early, as we may begin reviewing applications before the deadline.
