Sr. Front-End Growth Engineer (AI First)

Worldwide Salaried Open

We’re seeking a

Senior Growth 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.

In addition to helping shape the future of AI-accelerated development at Everlywell, this role has a

growth engineering focus: driving measurable business impact through e-commerce performance optimization, A/B testing, and conversion rate improvements on everlywell.com. You’ll collaborate with product, design, and analytics to experiment, measure, and scale high-impact changes to user experience 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 commerce.

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, Design, and Growth teams to implement CRO-focused experiments, including A/B tests, multivariate experiments, and personalization strategies.
  • Continuously optimize site speed, checkout performance, and user journeys to improve conversion and customer satisfaction.
  • Contribute to our internal growth experimentation framework, including analytics instrumentation, experimentation infrastructure, and performance monitoring.
  • 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.
  • Experience implementing growth-focused web experiments, and driving impact through data-informed design and optimization.
  • 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.
  • Bonus: Experience with e-commerce platforms, CRO tools (e.g., Google Optimize, Optimizely, or internal A/B platforms), Ruby on Rails, or DevOps tools 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
