AI-powered scalable infrastructure + mental health services, starting…. Backed by Y Combinator.
About the role
We are rebuilding how engineering happens at LunaJoy. Modern AI coding tools, Claude Code, Cursor, and Codex, can now write the majority of production code under human direction. The bottleneck has moved from typing code to scoping problems tightly enough that a fleet of AI agents can execute them without producing pull requests that miss the point. High-impact engineering today isn’t just fast coding; it's about strong systems thinking, sharp specs, and disciplined reviews.
What they're looking for
- Lead the architecture, design, and implementation of scalable software systems with embedded AI components
- AI infrastructure and agent orchestration. Claude Code workflows, n8n automation flows, agent feedback loops, and the self-improvement infrastructure that makes our agents better over time
- The codebase migration to an AI-readable structure. CLAUDE.md hierarchy, file-header docstrings, characterization tests on legacy modules, and strangler-fig migrations of high-risk areas
- Specification and review quality. You write the specs that fleets of agents execute against. You are the final review gate for production-bound code
- HIPAA-adjacent technical decisions. This role touches PHI. You own the discipline that keeps us compliant and our patients safe
- Work closely with data scientists and product managers to translate business needs into technical solutions using ML/AI models
