About the role

  • Design, implement, and scale foundational backend systems and APIs that power decentralized, real-time AI workflows.
  • Own the end-to-end developer journey by building SDKs, CLIs, and interfaces that make it easy to interact with our platform.
  • Rapidly prototype and productize features using tools like Cursor, React, and TypeScript—without sacrificing quality or scale.
  • Guide architectural decisions, lead design reviews, and mentor engineers in best practices for distributed, high-performance systems.
  • Partner with product, design, and leadership to align technical execution with company vision and user needs.
  • Drive key projects from 0→1 with autonomy, accountability, and a strong bias for action.

Requirements

  • 4+ years in high-performance software environments, with a proven track record of shipping complex systems end-to-end.
  • Mastery of one or more systems languages (Go, Rust, Kotlin, etc.) and strong backend engineering fundamentals.
  • Experience designing and scaling distributed systems with performance, reliability, and observability in mind.
  • Strong discipline around testing, CI/CD, and long-term maintainability (TDD preferred).
  • Ability to turn ambiguity into architecture, and architecture into reliable, extensible code.
  • Clear, concise communicator who can explain tradeoffs, write technical specs, and mentor junior engineers.
  • Bonus: Experience with edge computing, Web3 protocols, real-time data infra, or AI/ML-powered systems.

Benefits

  • Competitive Compensation & Meaningful Equity: We offer founder-level alignment because this is a founder-level role.
  • High-Ownership Role: You’ll directly shape our technical direction and long-term stack architecture.
  • Work with Top-Tier Founders & Engineers: Collaborate daily with a deeply technical, mission-driven leadership team.
  • Build the Future of AI Infrastructure: We're not optimizing yesterday's workflows—we're inventing tomorrow's.
  • Zero Bureaucracy, Maximum Autonomy: We stay lean, move fast, and trust you to lead.
  • Remote-First, In-Person When It Counts: We're distributed across SF and Europe, with monthly hackathons and off-sites to align and build together.
