About The Position

Hopper's technology powers some of the largest travel portals in the world through its Hopper Technology Solutions (HTS) platform, which drives travel purchases for major global brands. This platform is a configurable, multi-tenant travel commerce engine enabling partners to launch hotel and travel booking experiences faster with less custom engineering. The company is seeking a senior software engineer who builds great products and leverages AI to do so efficiently. This role involves orchestrating agents, building feedback loops, and shipping features end-to-end at an accelerated pace. The ideal candidate understands the strengths and weaknesses of LLMs and can determine when to trust AI output and when to intervene. This role offers the opportunity to ship features, improve the Software Development Life Cycle (SDLC) for peers, enhance business intelligence, and unlock new capabilities for millions of travel customers worldwide, with limitations defined only by imagination. This is a remote role.

Requirements

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.
Backend: Scala, GCP services
Frontend: React + TypeScript
Stack-agnostic thinking: experience with systems in Go, Python, Java, or similar languages is valued, with a focus on fast learning.

Responsibilities

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.
