Senior Full Stack Product Engineer

Did you know Hopper's technology powers some of the largest travel portals in the world? Our Hopper Technology Solutions (HTS) platform drives travel purchases for major global brands — from banks to airlines to fintech leaders. This platform is a configurable, multi-tenant travel commerce engine, enabling partners to launch world-class hotel and travel booking experiences faster, with less custom engineering. We're looking for a senior software engineer who builds great products and has figured out how to use AI to do it at a pace that wasn't possible a year ago. You're not using AI to auto-complete your code — you're orchestrating agents, building feedback loops, and shipping features end-to-end in a fraction of the time it used to take. You understand the strengths and weaknesses of LLMs, and you've developed the taste to know when to trust the output and when to intervene. We need thinkers who can build products end to end...who can change the way we build products end to end. In this role you will ship features, improve the SDLC for your peers, supercharge business intelligence, unlock new capabilities for millions of travel customers worldwide. You will be limited only by your imagination. This is a remote role. TECH STACK - Backend: Scala, GCP services - Frontend: React + TypeScript - We value stack-agnostic thinking. If you've built great systems in Go, Python, Java, or anything else, and you pick things up fast — that's what matters. WHAT YOUR DAY-TO-DAY WOULD LOOK LIKE - Identify and execute improvements to the codebase that make it easier for both humans and AI agents to move fast and ship safely. - Work with a group of senior engineers in a low-process environment powered by trust and autonomy. - Drive decisions and consensus asynchronously with thoughtful documentation and specs. - Build new features from top to bottom — from UX to database. Ship fast. Learn fast. Repeat. - Architect scalable solutions and foundational patterns that let us efficiently launch new partner experiences. - Work directly with PMs and business partners to define and refine our roadmap. Your voice and technical vision matter. - Collaborate with a diverse group of people, giving and receiving feedback for growth. AN IDEAL CANDIDATE HAS - A natural drive to fearlessly dive into an unknown codebase and deliver results fast. - Strong product thinking — your conception of quality and architecture is anchored in the customer experience, not in technical elegance for its own sake. - The ability to direct AI agents and automated workflows to build and maintain complex systems, and the judgment to know when to step in and when to let them run. - Experience designing the guardrails and feedback loops that keep AI-assisted development productive and reliable. - Experience with, or a mastery-level willingness to learn, distributed system development in Scala. - The ability to articulate not just how you'd solve a problem, but why, and what tradeoffs you're accepting. 🇺🇾 Contractor Disclosure: Uruguay 🇺🇾 This position is offered as an Independent Contractor role (Prestación de Servicios) based in Uruguay, supporting the Hopper Cloud / HTS (Hopper Technology Solutions) business unit.
