This early-stage team is building the foundation for enterprise AI—deploying autonomous agents that deliver specialized services with human-level quality. Founded by builders from companies like Google, Databricks, and Canva, they’re moving fast to turn ambitious ideas into real-world systems.

As one of the first platform engineers, you’ll help define, architect, and build the systems that make everything possible. Cognitive agents, context graphs, observability, developer tools—this is zero-to-one, high-ownership work with massive technical depth. You'll be hands‑on in setting the technical direction, making foundational choices, and scaling the infrastructure that real‑world AI deployments depend on.

What You’ll Tackle
  • Architect and build core platform components—structured context graphs, observability layers, tagging and discovery systems.
  • Design scalable APIs and frameworks that drive AI‑powered workflows across multiple industries.
  • Build bi‑directional Git integrations and interfaces that make developer and non‑technical user workflows seamless.
  • Own platform infrastructure decisions end‑to‑end—from strategic design to hands‑on implementation.
  • Collaborate across backend, product, and AI engineering teams to launch high‑quality systems fast.

Why You’ll Want to Join
  • Founding seat at a venture‑backed, mission‑driven AI company.
  • Huge technical ownership—architect, build, and scale the systems that everything else depends on.
  • Tight‑knit, high‑velocity team—no endless approvals, just smart people building quickly.
  • Real‑world AI impact—enterprise deployments in industries that matter, not toy projects.
  • Competitive comp and meaningful equity upside.
