We're seeking a
Senior Frontend Engineer
with deep expertise in
React
and
Next.js , who is ready to embrace an
AI-first engineering culture
- where artificial intelligence is not a novelty, but a 10x force multiplier that enhances your ability to ship exceptional products faster, smarter, and with greater confidence.
You'll collaborate with product, design, and analytics to experiment, measure, and scale high-impact changes across user experiences and checkout flows. This is an ideal role for frontend engineers who are not only passionate about building modern, scalable UI - but also energized by experimentation, data, and impact at the intersection of health and technology.
What You'll Do:
Develop performant, modular applications using React, Next.js, and TypeScript, backed by a robust and evolving Design Language System (DLS). Use AI-first tools (e.g., Cursor, Copilot, AI-assisted code search, and automated refactoring) to radically accelerate day-to-day development and maximize creativity. Partner with Product and Design teams to implement experiments including A/B tests, multivariate experiments, and personalization strategies. Continuously optimize site speed, user journeys, and overall web performance to improve conversion and customer satisfaction. Help define and promote AI-enhanced coding practices, integrating intelligent tooling into our dev workflows, CI/CD, and code review culture. Ensure high-quality output through automated and AI-assisted testing, error monitoring, and performance tracking. Collaborate across product, design, and backend teams to deliver full-stack features that delight our users and support healthcare innovation. Who You Are:
