Senior Rails & AI Product Engineer · Ruby on Rails since 2008 · remote with US and European teams since 2011 · UTC+8
I build and maintain Rails products and the production AI workflows inside them: structured outputs, tool calls, retries, human review, evals and cost control. Real features, not one-off demos.
- Senior roles — open to senior Rails and AI product engineering work
- Rails Maintenance & AI Integration — support for existing Rails SaaS apps
- VibeCare — monthly care for AI-built and vibe-coded apps
- Accessibility Reviews & Fixes — so everyone can finish sign-up, checkout and key forms
