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.
- Own features end-to-end — from the backend systems to the partner-facing surface. You'll primarily work on the backend, but expect to use AI tooling to move across the stack as needed. We care that you can ship a complete feature, not that you can write production-grade React from memory.
- 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- 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.
