Full Stack Software Engineer

CO-Ver helps owners and developers review, validate, and challenge construction change orders before payment. The Full Stack Software Engineer will build and maintain production web applications involving document ingestion, scope and cost comparison, workflow automation, and LLM-assisted analysis across the stack.

Requirements:

• Strong TypeScript and React/Next.js
• solid data modeling
• experience shipping and maintaining production web apps
• experience building features where an LLM makes a judgment call or decision as part of the application flow, not just generates text
• think in systems and reason about tradeoffs across the stack
• can take a defined problem to a working feature without every step spelled out
• make good calls when guidance is incomplete while staying aligned with the team
• PDF/document pipelines
• multi-tenant architecture and auth patterns
• testing (Vitest/Jest/Playwright)
• agentic coding tools (Claude Code, Cursor, etc.) in a production codebase
• model-selection tradeoffs across providers (cost, latency, capability)
• construction domain knowledge
