Senior Full-Stack Engineer (Go + Next.JS + React Native)

• 5+ years of full-stack experience; strong in Go (or deep TypeScript experience and proven ability to pick up Go fast).
• Solid React/Next.js; React Native experience is a major plus.
• Comfortable with webhook-driven / telephony / event-based systems — you've debugged async flows across service boundaries.
• Able to read and navigate a large, unfamiliar codebase independently.
• Strong SQL and comfort operating PostgreSQL in production.
• English C1+ written and spoken.
• Based in Latin America with at least 6 hours of overlap with US Pacific time.

• Fix bugs at the root cause: triage reports from live users, trace them through the full stack, and fix the underlying problem — not the symptom.
• Harden reliability: improve test coverage, observability, and error handling across a system built at high velocity.
• Ship features: case-opening automation, workflow tooling, telephony improvements, AI-assisted document workflows.
• Own production: deploys, database migrations, and occasional on-call for critical issues.

California Injury Group, APC (CIG Law) is a growing personal injury law firm in Los Angeles.

The entire firm runs on it every day.

You'll be our first full-time engineer, working directly with the firm's owner — no PM layer, no ticket bureaucracy. The product has real daily users (our staff) who report bugs and request features constantly, so your work ships fast and gets used immediately.
