What you will do

  • Architect and ship the core services that power our multi-agent AI workflows: rock-solid restful APIs, data models built for evolution, and deployment/debug tools that just work.
  • Troubleshoot critical issues in production, mentor peers on system design, and evangelize best practices across services and languages.
  • Partner directly with customers: jump on customer calls, diagnose pain points, and deliver impactful improvements in hours, not quarters.

What they are looking for

  • Have 2+ years of backend engineering experience and a solid foundation in both Computer Science and software engineering principles. We're also open to exceptional college grads with strong intern/co-op experience.
  • Are fluent in Python and TypeScript and have worked with FastAPI and/or NextJS in the past.
  • Understand how databases (KV, SQL, Document based) work, when each of them should be used and how they can be optimized.
  • Have previously developed, tested and scaled RESTful APIs in the past.
  • Are self-motivated, like to take ownership, have low ego; desire to work on a fast-paced, intense, fun team.
  • Passion for building a world-class engineering culture.
  • Are product-focused, understanding that technology is a means to build an amazing product, not an end in itself.
  • Value code quality, but are pragmatic, shipping fast when needed.
  • Are excited about AI/ML applications and have previously worked in LLMs, agents, and automation

Nice to have

  • Knowledge of OOP design patterns, clean architecture, event sourcing and Test Driven Development.
  • Experience with DevOps tooling: Docker, Kubernetes, Github Actions and cloud platforms.
  • Thorough knowledge of the Linux operating system.

Benefits

  • Significant founding team equity.
