LumiMedsAbout the role
About LumiMeds
LumiMeds is a fast-growing U.S.-based telehealth startup focused on weight management and long-term metabolic health. We are building the next generation of e-commerce and clinical infrastructure from the ground up.
As an early-stage company, we move quickly, operate with limited layers, and expect high ownership from every team member. There is no bureaucracy here — decisions happen fast, priorities evolve, and builders thrive.
We are a remote-first, globally distributed team that values clarity, accountability, and people who take initiative rather than wait for direction.
Seniority: Mid-Level / Senior (Individual Contributor)
Role Overview
LumiMeds is a high-growth telehealth platform building the next generation of virtual telehealth infrastructure. We are looking for an AI-First Frontend Engineer who builds beautiful, performant, and clinically reliable interfaces —and uses AI to do it at a pace that consistently surprises people.
You are not a designer who codes, nor a utility developer who ships components on request. You are an engineer who can translate a Figma frame into a pixel-perfect, highly performant Next.js experience, architect the state model behind it, and use AI tooling to compress a week of work into a day. You know how to direct Claude agent teams to handle parallelizable work — generating component variants, writing test suites, auditing accessibility — so you can stay focused on the decisions that require human judgment. You will balance 90% hands-on coding with 10% mentorship, and you are expected to set the bar for frontend quality and velocity on the team.
Core Technical Domains
You will own the user-facing layer across our consumer and clinical platforms:
- Performant Marketing & E-commerce: Engineering lightning-fast, SEO-optimized storefronts and landing pages. You treat Core Web Vitals as a first-class deliverable.
- Clinical Web Application (EMR & Provider Portal): Building the “Clinical OS” — complex, state-heavy interfaces where data integrity and reliability are non-negotiable.
- AI-Powered UI Features: Implementing streaming LLM responses, real-time clinical summaries, and conversational interfaces embedded into patient and provider flows.
- Virtual Care Interfaces: Implementing WebRTC video components, real-time secure messaging, and low-latency async consultation flows.
- Design System & Motion: Maintaining a component library using Framer Motion to produce purposeful animations that make the platform feel premium and intuitive.
Key Responsibilities
- AI-Augmented Frontend Development: Use Cursor, Copilot, and LLMs as first-class tools to generate components, write tests, and iterate on UI logic at high velocity. Prompt quality is part of the craft.
- Claude Agent Team Orchestration: Coordinate Claude agent teams via the Claude Agent SDK to execute parallelizable frontend work — generating component variants, writing test suites, auditing accessibility, and producing design-to-code translations at scale. You know how to structure agent prompts, verify outputs, and integrate agent-generated code into the production codebase reliably.
- Aesthetic Engineering: Translate high-fidelity Figma designs into pixel-perfect, responsive experiences that hold visual integrity across all device sizes and breakpoints.
- Performance Ownership: Own Core Web Vitals — optimize LCP, INP, and bundle size. Understand hydration, streaming SSR, and caching strategies at a deep level.
- AI UI Integration: Build and maintain frontend interfaces that consume LLM outputs — streaming text, structured responses, tool-call results — in ways that feel fluid and reliable to end users.
- State Architecture: Design resilient client-side state capable of handling real-time clinical data, optimistic updates, and complex form flows across the patient journey.
- Compliance & Security: Ensure all interfaces meet HIPAA/SOC2 standards, with a focus on secure data handling, audit trails, and PII protection.
Required Hard Skills & Tech Stack
- Next.js Mastery: Expert-level knowledge of the App Router, Server Components (RSC), and sophisticated caching/streaming strategies.
- The “Beautiful Web” Stack: Expert proficiency in Tailwind CSS and Framer Motion for fluid, high-end interfaces.
- Performance Optimization: Proven track record optimizing bundle sizes, hydration cycles, and Lighthouse scores.
- State Management: Expertise in TanStack Query (server state) and Zustand (client state).
- LLM UI Patterns: Experience building streaming response UIs, cha
