Overview

Everlywell is a digital health company pioneering the next generation of biomarker intelligence—combining AI-powered technology with human insight to deliver personalized, actionable health answers. We transform complex biomarker data into life-changing insights—seamlessly integrating advanced diagnostics, virtual care, and patient engagement to reshape how and where health happens.

Over the past decade, Everlywell has delivered close to 1 billion personalized health insights, transforming care for 60 million people and powering hundreds of enterprise partners. In 2024 alone, an estimated 1 in 86 U.S. households received an Everlywell test, solidifying our spot as the #1 at-home testing brand in the country. Fueled by AI and built for scale, we’re breaking down barriers, closing care gaps, and unlocking a more connected healthcare experience that is smarter, faster, and more personalized.

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

• 4–6+ years of professional experience in frontend web development.
• Advanced proficiency with React, Next.js, and TypeScript.
• Passionate about AI’s role in modern engineering — not just as an efficiency tool, but as a creative and cognitive multiplier.
• Hands-on experience with AI-powered dev tools like Cursor, GitHub Copilot, Codeium, or equivalents.
• Strong understanding of software engineering best practices — including component design, state management, and automated testing.
• Familiarity with backend integration (REST, GraphQL) and performance optimization for modern web apps.

Nice to Have

• Experience with e-commerce, growth engineering, or conversion rate optimization (CRO) techniques.
• Familiarity with CRO tools (e.g., Google Optimize, Optimizely, or internal A/B platforms).
• Experience with Ruby on Rails or DevOps tooling like Docker, Jenkins, and AWS CodeBuild.

Why You’ll Thrive at Everlywell

• AI-first culture focused on velocity and developer empowerment.
• Real opportunity to multiply your output and influence with the latest tools and practices.
• Mission-driven company with top-tier backing.
• Flexible remote work and open PTO policy.
• Health, vision, dental + 401(k) with company match.
• Paid parental leave and family-first benefits
