About the role

Job Summary

We are looking for a Senior Backend Engineer to contribute to our vision and development of Agentic AI tooling and platforms through technical leadership and proactive thinking. Our product is an orchestration platform that enables developers to spin up isolated, AI-powered development sessions that autonomously work on tasks - from Jira tickets to GitHub issues.

The team operates without a dedicated product manager; you will be expected to identify problems worth solving, define requirements, and own features from problem statement to production deployment.

Technical Stack

  • Rust for CLI tools and API server
  • React 19 with TypeScript for frontend
  • Kubernetes with Helm on Google Cloud for infrastructure

Responsibilities

Your specialization in backend development - API design, async web frameworks, authentication, databases, and service architecture - will make you the team's anchor for the API server and backend systems. You will regularly touch frontend code and infrastructure as the work demands.

The team operates in a startup fashion with a heavy focus on experimentation and prototyping solutions first and evaluating what works in practice rather than heavy upfront requirements given how quickly the agentic space moves.
