WeTravel - Senior Product Engineer
Requirements
• Order management: building the foundational systems for organizers and travelers to view, modify, and manage reservations end-to-end - changes, transfers, cancellations, and everything in between. • Order management: • Tax management: expanding our tax capabilities across jurisdictions so organizers can sell compliantly wherever their travelers are. • Tax management: • Reliability and structural improvements: scaling our booking flows to support 10x growth. • Reliability and structural improvements: • 7+ years of product engineering expertise, with 4+ years dedicated to architecting complex e-commerce, booking, or order management systems. • Proven track record within a high-scale consumer checkout, marketplace, travel, or e-commerce platform team. • Broad practical expertise in building and troubleshooting production-level checkout and order flows: conversion-critical funnels, pricing and tax calculation, availability and inventory, cancellations, modifications, and refund flows. You possess deeply ingrained expertise in order state machines, multi-step form UX, and the operational tooling that keeps commerce systems running. • Strong backend mastery in Ruby on Rails, Kotlin, Python, Go, Java, or Node.js with the agility to ramp up on Ruby quickly. • Full-stack comfort: you can build the React interface for the booking flows you architect. • Deep expertise in architecting robust, resilient distributed systems, including order and reservation state machines, idempotency, exactly-once semantics, event-driven architectures, webhooks, and reliable consumer patterns. • Direct production on-call experience, including authoring post-mortems and leading incident response. • Excellent written and verbal communication skills, including cross-functional collaboration experience, and the ability to thrive in a distributed, multicultural environment. • Pragmatic adoption of AI tools to optimize your engineering workflow, including the ability to mentor and train others on AI concepts. • Strong background in cloud infrastructure (AWS/GCP), containerization, and modern CI/CD practices. • Experience in handling critical systems with precision: you will handle pricing and tax logic directly within the application layer. • Bonus: Direct experience with tax engines or multi-jurisdiction tax compliance (VAT, GST, sales tax), or with travel-industry reservation systems. • Experience launching or significantly redesigning a checkout or booking flow end-to-end. • Experience building tax calculation or compliance capabilities across multiple jurisdictions. • Experience in marketplace or two-sided platform commerce (orders spanning buyers, sellers, and modifications over time). • You might not be the right fit if you: • Your commerce expertise is limited to plugging in off-the-shelf checkout or cart solutions. We need someone who operates deeply beneath that abstraction layer. • You are hesitant to take full ownership of mission-critical booking flows or participate in the on-call rotation when systems fail. • You prioritize greenfield development over the complex challenge of scaling and refining an existing system with significant booking volume. • You are looking for a siloed IC position without the need for cross-functional collaboration or product-level discovery. • You require a rigid, pre-defined roadmap; we prefer to sharpen our strategy and direction as we scale the team.
Responsibilities
• Lead booking projects end-to-end: discovery with Product and Customer teams, solution design, build, rollout, monitoring, and incident response. • Partner with the Product team to gain insight into organizer and traveler challenges, building booking experiences that convert and delight. • Own the reliability of our booking and order management systems • Contribute to WeTravel's engineering practices and excellence. • How we work: • We're using the latest hardware and constantly on the look out for better tools & ways to work. • We have AI-first development experience and work with the latest models and agentic dev tools. • Stack: We're developing React/TypeScript, Ruby on Rails and Kotlin Microservices.
