Job Description

Do you want to own architecture delivery and release for a fast-moving AI-native product line not just write code for one Can you turn a rough roadmap into a sequence of self-contained agent-ready Linear tickets without anyone needing to ask a follow-up question Have you made Claude Code and your daily driver for coding planning and ticket-writing and built your own skills hooks or MCP integrations on top of them Can you judge in seconds when AI-generated code needs a second look especially around auth access control or anything destructive Do you thrive in fast ambiguous unscoped delivery rather than traditional phased client work If you answered yes then we want to talk to you!

We need a full-stack tech lead to own fast-moving AI-native products end-to-end and to be the person who turns roadmap into shipped software through well-run Linear tickets realistic timelines and clean releases.
