Job description
You will be the senior IC anchoring a small build team, shipping production code from week one. This is not a consulting engagement-you'll own architecture decisions, work directly alongside the CTO and Claude Code, and move fast without hand-holding.
You'll lead development of a sophisticated multi-tool AI platform comprising 12 integrated systems: admissions, SIS, scheduling, onboarding, Field Execution PWA, Room and Board app, ticketing, inventory, HR, student portal, plus our AI agent Morgan and the underlying multi-agent platform.

- Guide best practices in full-stack development and AI production environments
- Collaborate with cross-functional teams to deliver on aggressive timelines
Requirements
- Proven full-stack shipping experience with Next.js 14 (App Router) and TypeScript
- Production AI application development-you've shipped AI-integrated apps end-to-end, not just experimented
- Expertise with Supabase (Postgres, RLS, pgvector) for database management
- Familiarity with Railway or similar deployment platforms
- Builder mindset-you thrive on ownership, not waiting for specs
- Strong leadership and ability to work autonomously, * Experience with Anthropic Claude API and LLM-based architectures
- Track record working remotely across US time zones
- Background in EdTech, operations tools, or veteran-serving organizations
- Comfort with rapid iteration and adapting to changing requirements, A senior engineer who has shipped production AI apps, can own complex architecture decisions, and moves fast without hand-holding. You should be comfortable being the technical anchor for a small team hitting a hard deadline.
