  • Polyglot Fullstack Execution: You’ll be shipping high-quality code across Python and TypeScript with the curiosity to chip in with other languages like Go and Rust.
  • High-Bandwidth Collaboration: Working in-office from our Culver City headquarters, you will collaborate daily with senior engineers to solve complex distributed systems challenges in real-time.
  • Fueling High-Velocity Growth: Build at the intersection of AI, fintech, and Bitcoin infrastructure (and eat well, lunch is on us)

  • High-Impact Collaborative Ownership: We are an in-office company located in Culver City, designed for those who thrive on daily, high-bandwidth collaboration. We need engineers with an appetite for ownership and a high bar for your own output.
  • AI-Native Rapid Prototyping: You hardly ever manually write code these days. you leverage agentic tools (ex: Claude, Cursor) to multiply your output.
  • Mission-Driven Technical Curiosity: You have a deep-seated interest in fintech, crypto, or related technologies.
  • Adaptive Technical Agility: You are a flexible builder with hands-on programming experience via personal projects, hackathons, or coursework.
