About the role

  • You've shipped multiple complete products end-to-end and write elegant, production-ready code across multiple disciplines.
  • Specific interest in applying software engineering fundamentals to AI systems.

Responsibilities

  • Build agents that write, test, and deploy their own software packages?
  • We're backed by Anthropic, Blackstone, Hellman & Friedman, Goldman Sachs, General Atlantic, Leonard Green & Partners, Apollo Global Management, GIC, and Sequoia Capital.
  • Regular events to build camaraderie and a strong team spirit.
  • We design systems around testable hypotheses, curate durable data sets, and ensure what we ship keeps working long after we've handed it over.
  • The upside is constant time on the frontier of models and tooling, and a muscle for AI product development that's hard to build anywhere else.
  • 🎉 Team Events and Activities: Regular events to build camaraderie and a strong team spirit.

Requirements

  • 8+ years of engineering experience, with deep care for the craft.
  • Comfort talking with senior technical stakeholders.
  • You have outsized autonomy on each product - but you won't have a year to polish a single system.
  • 8+ years of engineering experience, with deep care for the craft. You've shipped multiple complete products end-to-end and write elegant, production-ready code across multiple disciplines.
  • Specific interest in applying software engineering fundamentals to AI systems. You care about balancing frontier model capabilities with good system design.
  • Comfort talking with senior technical stakeholders. You navigate conversations skillfully, and care about people using what you build.
