• 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.
