About the role

Key responsibilities & impact

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.

Requirements

What you’ll need

Experience designing the guardrails and feedback loops that keep AI-assisted development productive and reliable.
The ability to articulate not just how you'd solve a problem, but why, and what tradeoffs you're accepting.
Strong product thinking — your conception of quality and architecture is anchored in the customer experience, not in technical elegance for its own sake.
Natural drive to fearlessly dive into an unknown codebase and deliver results fast.
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 with, or a mastery-level willingness to learn, distributed system development in Scala.
