About the Role

We're looking for a Senior Software Engineer to join our Admin & Travel Policy team — the group that powers the configuration layer B2B admins use to run their travel programs. You'll be driving our migration from a Ruby on Rails monolith (Nexus) to TypeScript microservices.

This is high-ownership work. When your team changes a permission structure or updates a travel policy, it ripples across cards, flights, hotels, and bookings — meaning you'll collaborate constantly with other verticals and architect for system-wide impact. You'll also help close a real gap in A/B testing and event tracking on the team.

The team is AI-forward. You'll use AI tooling in your daily workflow — this isn't optional, it's how we build.

What You'll Do

• Own frontend surfaces of admin-facing travel policy features end-to-end
• Drive migration of admin surfaces from the Ruby on Rails monolith to TypeScript microservices
• Supply policy and permission data to cars, flights, and hotels verticals — coordinating closely with those teams to ensure search performance and conversion are not impacted
• Introduce and improve A/B testing and event tracking on the team
• Collaborate cross-functionally with card, booking, flights, and hotels teams on permission and policy changes
• Help build AI-integrated admin interfaces that allow B2B admins to manage policies through Slack, text, and other AI-native channels
• Operate in a platform-adjacent capacity — your changes affect multiple stacks, and you'll navigate that complexity with care

What We're Looking For

Required:

• Strong TypeScript and/or React skills — frontend-heavy profiles are preferred
• Ruby on Rails experience — you'll work in Nexus throughout the migration
• Proven ability to work in cross-team or platform-adjacent codebases where your changes affect multiple systems
• AI-forward mindset — you actively use AI tooling in your coding workflow

Nice to Have:

• AWS microservices experience (ECS, Lambda)
• A/B testing or event tracking experience (Amplitude or equivalent)
• NoSQL databases
• Java or Kotlin background
