full-stack engineers

You’ll own and evolve key backend systems that power the Codegen platform. This includes distributed task execution for AI-driven “solves,” developer sandbox orchestration and lifecycle management, and systems for ingesting and retrieving customer knowledge. You’ll prototype new features end-to-end, then scale and harden them for production use. Working closely with a high-trust, fast-moving team across product, infrastructure, and AI, you’ll ship real systems used by developers daily - from Slack workflows to production environments., * Own and evolve core backend systems, including:

• Distributed task execution for AI-powered “solves”
• Developer sandbox orchestration and lifecycle management
• Customer knowledge ingestion and retrieval
• Prototype features end-to-end, then harden them for scale and reliability
• Collaborate with a high-trust, fast-moving team across product, infra, and AI
• Ship real systems that developers use daily - from Slack to production
