Job Title : Full-Stack Software Engineer (Next.js, Supabase, Cloudflare Workers)

About the Role

Were hiring a Full-Stack Software Engineer to build secure, performant web applications with a modern stack centered on Next.js, Supabase (PostgreSQL), and Cloudflare Workers. Youll ship end?to?end features, from responsive UIs to edge-deployed APIs, with a focus on reliability, developer ergonomics, and real-world user impact. Experience in health tech and interest in LLM agents and real?time / voice experiences is a big plus.

What Youll Do

Build features across the stack using Next.js (App Router, RSC, route handlers), TypeScript, and Tailwind CSS.
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 APIpowered features.
Integrate LLM agent capabilities (tool use, retrieval, workflows) where they materially improve UX.
Uphold security?by?design and privacy best practices; contribute to HIPAA / PHI?aware development in a regulated environment.
Write clean, testable code (unit, integration, and E2E), and participate in code reviews and CI / CD.
Monitor production with observability tooling; drive performance, accessibility, and SEO improvements.
Collaborate with design and product from discovery to delivery; document decisions and architectural tradeoffs.

Required Qualifications

3+ years building production web applications.

Strong TypeScript, React / Next.js skills; familiarity with SSR / ISR, data fetching patterns, and performance profiling.

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.

Tailwind CSS expertise for building responsive, accessible, and maintainable UIs.

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).

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.

Testing / Observability : Playwright / Vitest / Jest, OpenTelemetry, Sentry or similar.

Competitive salary, equity, and comprehensive benefits.

Flexible hybrid work (West Hollywood, CA 23 days / week on-site).

Learning budget, modern tooling, high?performance hardware, and opportunities to lead projects.
