  • FullTime

Build the operating system for intelligent, empathetic AI companions.

We’re designing the core runtime that lets AI companions perceive, reason, remember, and act. As our Founding Engineer, you’ll co-own architecture and ship v1s that become the backbone of the product.

What you’ll do

  • Design and build Python backend services and APIs powering real-time AI companion behavior.
  • Define core system architecture: process boundaries, state management, storage, orchestration, and reliability.
  • Move fast on 0→1 features; prototype, test with users, iterate.
  • Own the full lifecycle: design docs, implementation, deployment, monitoring, and incident response.
  • Set engineering culture and best practices as an early pillar of the team.

You’ll thrive here if you…

  • Have startup experience or have built and shipped your own startup/product.
  • Love building things end-to-end, cherish problem-solving, and are comfortable being hacky/scrappy when it’s the fastest path to learning.
  • Maintain and can share independent projects—please include your GitHub and links to things you’ve shipped.

Must-haves

  • Strong Python backend experience.
  • Solid system design and API design fundamentals (latency, scalability, data modeling, versioning, observability).

Nice-to-haves (not required)

  • Experience with PyTorch or JAX.
  • Familiarity with operating systems and runtimes or ROS/ROS2-like systems.
  • Background in real-time systems, streaming, or agent architectures.

What do we offer?

  • USD-based compensation and equity/stock options
  • Work with a globally curious and fast-paced team
  • Collaborate with a talented, fast-moving, and supportive international team.
