Senior Frontend Engineer (Next.js & React, AI-Native) - Remote at Lumimeds

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.

Platform & Product Engineering — LumiMeds

Location: Remote / Hybrid
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, chat interfaces, or AI-assisted input flows using OpenAI or Anthropic APIs.
Claude Agent Teams: Hands-on experience building and directing Claude agent teams using the Claude Agent SDK — from bulk component generation to automated visual regression and test coverage. You can design an agent pipeline, define subagent roles, and validate the output before it lands in production.
AI Dev Tooling: Daily active use of Cursor, GitHub Copilot, or equivalent. Strong opinions on how to use AI for component generation, refactoring, and test writing.
Browser Fundamentals: Deep understanding of the DOM, rendering pipeline, and HIPAA-compliant data handling in the browser.

Candidate Qualifications

3+ years of professional frontend engineering experience.
AI-Native Workflow: You can demonstrate concretely how AI has accelerated your frontend output. Examples or portfolio required.
The Dual-Threat Portfolio: Proven experience building both visually polished, high-traffic marketing sites and complex, data-driven SaaS applications.
Uncompromising Eye for Detail: You notice when spacing is off by 2px and care enough to fix it. Typography, micro-interactions, and motion are part of your craft.
High Agency: Ability to self-direct, operate in ambiguity, and make high-leverage frontend decisions without constant supervision.
Communication: Professional proficiency in English for technical documentation and cross-functional collaboration.

Why Join LumiMeds?

AI as Infrastructure: We don’t bolt AI on — it’s embedded in how we build. You’ll be encouraged and expected to use every tool available to ship faster and better.
Design-Forward Culture: We believe healthcare should be beautiful. You’ll have the technical freedom to build a premium brand experience without compromise.
Direct Impact: Fast, intuitive, and beautiful interfaces directly affect patient outcomes and provider efficiency.
