About mTripmTrip is an all-in-one travel technology platform for travel agencies, tour operators and travel management companies. Agencies use our web platform to build itineraries; their travelers get them in branded iOS and Android apps and on the web, with real-time flight alerts, documents, notifications and risk management. Our clients run trips on every continent. The engineering team is small, so every developer ships features end to end and has a real say in how the product is built. The roleWe are hiring a Full-Stack Developer (Ruby on Rails / Vue.js) to build and maintain the SaaS platform. You will own features from the database to the browser: Rails models and services, JSON APIs consumed by our mobile apps, and the Vue.js screens our agency clients use every day. The codebase is large and mature, and we keep it current: it moved from Rails 6.0 to Rails 8.1 in the last year. You will spend most of your time on product work, and part of it keeping the platform quick, secure and up to date.

What you'll do
• Build product features end to end: itinerary building tools, traveler communications, document generation, real-time travel alerts and AI-powered features
• Design JSON APIs and integrations with travel partners (GDS such as Sabre, Amadeus and Travelport; flight-status, risk and messaging providers)
• Find and fix performance problems: N+1 queries, slow MySQL queries, heavy pages
• Write and maintain RSpec tests, including browser system tests, and keep the CI suite fast and reliable
• Take part in framework and dependency upgrades and security fixes
• Review pull requests and write documentation for the features you build
