High ownership, high expectations – You will be trusted to take initiative, make decisions and drive outcomes. Responsibility comes early, accountability is real, and results matter.

A fast‑moving, high‑performing team – You will work with smart, driven colleagues across the globe on complex problems. Standards and expectations are high, feedback is direct, and the pace is fast.

Continuous growth is the baseline – Everyone is expected and supported to learn quickly, improve constantly and raise their own bar. If you enjoy responsibility, momentum and meaningful challenge, you will thrive here.

What you’ll do:

• Continuously improve the codebase by simplifying solutions, reducing technical complexity and driving changes that have an impact across the team and system
• Guide and review implementation, including work produced through AI‑assisted workflows, ensuring quality, consistency and alignment with system design

What we’re looking for:

• Strong coding ability in JavaScript or TypeScript and at least one backend language, combined with the ability to evaluate, guide and refine implementation to reach production‑ready outcomes efficiently
• Proven experience building and shipping features in a fast‑moving product environment, with a track record of delivering high‑quality solutions with real impact
• Experience owning features end‑to‑end, including shaping requirements, making technical decisions and iterating based on feedback and outcomes
• Strong understanding of system design, with attention to architecture, abstraction and long‑term maintainability
• Experience using AI‑assisted development tools, or a strong interest in adopting them as a core part of how you design, build and iterate on software
