Senior Product Engineer - Supply Team

Almost no travel operator works alone. Agents, B2C tour operators and destination management companies buy from suppliers, resell each other’s trips, and split the money afterwards. Team Supply is building the layer that replaces it. You’ll join us to build that foundation and take it from early access to something thousands of operators depend on.

Responsibilities

Lead and build features end-to-end: from reviewing user interviews and product design, through architecture and building systems, to deployment and monitoring in production; Partner closely with our product team to discover user problems and shape their solutions, you’ll help decide what is worth building, not only how to build it; Write high-quality, maintainable code across both frontend (TypeScript/React) and backend (Ruby on Rails); Ensure our services are always on by building resilient applications, making sure they are well monitored, and mitigating incidents as an on-call/incident responder; Mentor teammates and contribute to WeTravel’s engineering practices and excellence

Requirements

7+ years of software engineering experience (ideally full-stack) with strong product ownership mindset; Hands-on experience with React and TypeScript, this one is a must. You’ve owned whole apps or large areas of a frontend, and you want to keep doing that; Solid backend experience in any recognized modern language: Python, Go, Java/Kotlin, .NET, Node/TypeScript, Ruby. Depth and engineering judgment matter to us more than the specific language; Built and launched something new in a startup or scale-up, and stayed with it as it grew (0 → 1 → 100); Breadth over narrow specialization: you’ve worked across the stack and across different kinds of problems, and you move to where the work is; Experience building applications working with distributed systems, microservices and event-driven architecture, with strong systems thinking and an eye for scalability; Experience operating applications in production: monitoring, alerting and on-call; Excellent communication skills and experience working in multicultural, distributed teams; Experience leading projects and mentoring other engineers; Experience using AI assistants like Cursor, Claude Code, Codex etc

Nice to have

Ruby on Rails. It’s our backend stack, so it’s a plus, but we hire for general engineering strength and expect a strong engineer to pick it up; Experience in an adjacent domain: marketplaces, supplier or vendor networks, payments and fintech, travel-tech, B2B2C platforms, or quoting / booking / costing systems. A plus, never a requirement; Comfortable running your own infrastructure (AWS / Kubernetes); Building and maintaining component libraries and working with a design system; micro front-ends; React Native; Recent experience in building AI-enabled or Agentic applications; Direct experience with customer interviews and user research
