Base pay range

$110,000.00/yr - $220,000.00/yr

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.
• 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.
• 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.
• 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.
