About the role

Key responsibilities & impact

Identify and implement improvements to the codebase to enable humans and AI agents to deliver quickly and safely.
Collaborate with a group of senior engineers in a lightweight, trust-based, autonomous environment.
Drive decisions and achieve consensus asynchronously through rigorous documentation and specifications.
Build new features end-to-end — from user experience (UX) to the database. Deliver, learn, and iterate rapidly.
Design scalable solutions and foundational models to efficiently launch new partner experiences.
Work directly with product managers (PMs) and business partners to define our roadmap. Your technical voice and vision matter.

Requirements

What you’ll need

A natural inclination to fearlessly dive into an unfamiliar codebase to deliver fast results.
Strong product sense — your conception of quality and architecture is grounded in customer experience, not in pure technical elegance.
Ability to steer AI agents and automated workflows to build and maintain complex systems, and the judgment to know when to intervene.
Experience designing safety guards and feedback loops to ensure the productivity and reliability of AI-assisted development.
Experience (or willingness to become proficient) in building distributed systems with Scala.
Ability to articulate not only how to solve a problem, but why, and which trade-offs you are accepting.
