Job description

Starfolk builds cloud development environments where engineers and coding agents work together. Agents can run services, test changes, and carry tasks through to completion. Engineers can collaborate live, delegate work, or take over whenever they need to.

About the Role

• Build services that manage cloud environments, agent sessions, and scheduled work.
• Design APIs and data models for coordinating tasks and handing work between engineers and agents.
• Connect Starfolk with GitHub, Slack, and the coding tools teams already use.
• Make workflows resilient to failures, retries, and interrupted connections.
• Improve performance, reliability, debugging, and compute efficiency.

Qualifications

• Have built and operated backend systems used by real customers.
• Understand APIs, databases, concurrency, and how to investigate production failures.
• Can turn an incomplete brief into a useful first version and improve it with feedback.
• Make thoughtful engineering tradeoffs, communicate clearly, and learn unfamiliar technology quickly.
• Care about how your technical decisions affect the people using the product

Required Skills

• Experience with developer tools, cloud infrastructure, containers, virtual machines, or coding agents is useful.
• You don’t need every item above to apply; tell us what you’ve built and what you learned.
