Senior Full-Stack Engineer

Job Title: Full-Stack Software Engineer (Next.js, Supabase, Cloudflare Workers) Location: Hybrid or Remote — if located in Utah or LA, hybrid is optional

About the Role We’re hiring a Senior Full-Stack Engineer to build secure, performant web applications and agentic systems with a modern stack centered on TypeScript, Supabase (PostgreSQL), and Cloudflare Workers. You’ll ship agentic features, with a focus on reliability and real-world user impact. Experience in health tech and real-time/voice experiences is a big plus.

What You’ll Do Build and deploy LLM-powered agentic systems, APIs, and services across the stack using TypeScript. Design and optimize PostgreSQL schemas; implement Supabase auth, RLS policies, and efficient queries. Develop and deploy serverless/edge logic on Cloudflare Workers (and related services like KV, Durable Objects, Queues, R2 where appropriate). Create robust APIs and integrations; apply caching, CDN, and edge strategies for latency and scale. Implement real-time interactions (Supabase Realtime/WebSockets) and, where applicable, WebRTC or voice API–powered features. Uphold security-by-design and privacy best practices; contribute to HIPAA/PHI-aware development in a regulated environment. Collaborate with design and product from discovery to delivery; document decisions and architectural tradeoffs.

Required Qualifications 4+ years building production web applications. Strong TypeScript, JavaScript, and Node.js skills. Experience developing fully-autonomous LLM agents, including fine-tuning, tool calling, and guardrails. Practical experience with Supabase or similar BaaS (PostgreSQL, auth, storage, migrations). Hands-on with serverless/edge runtimes (e.g., Cloudflare Workers) and RESTful API design. Solid grasp of authentication/authorization, data modeling, and secure coding practices. Proficiency with Git and modern DX: package managers, linters/formatters, testing, and CI/CD. Clear communication, ownership mindset, and collaboration in a hybrid work model.

Nice to Have LLM Agent Frameworks: familiarity with agentic patterns and tools (e.g., MCP, function/tool calling, Supabase Vector/pgvector, retrieval strategies, prompt/runtime safety). Next.js: familiarity with full-stack Next.js apps, including server actions and API routes. Real-Time & Voice: WebRTC fundamentals, WebSockets, and/or voice APIs like Twilio, Daily, Agora, Vonage, or browser Web Speech APIs. Health Tech: prior work with HIPAA/PHI, audit logging, data minimization, SOC 2, and healthcare standards (e.g., FHIR/HL7); familiarity with secure SDLC in regulated environments. Cloudflare Platform: KV, Durable Objects, R2, Queues; edge caching and multi-region data considerations. Python: familiarity and conversational fluency in Python, especially related to inference architecture. Product Mindset: experimentation/analytics, feature flags, telemetry-driven decisions.

Compensation & Benefits Competitive salary, equity, and comprehensive benefits. Flexible remote or hybrid work (Salt Lake City or LA would be hybrid). Learning budget, modern tooling, high-performance hardware, and opportunities to lead projects.
