Full Stack Engineer (Frontend Leaning)

Full Stack Engineer (Frontend Leaning) Join to apply for the Full Stack Engineer (Frontend Leaning) role at Healf.

Do Your Life’s Best Work If modern wellbeing were redesigned from scratch, it wouldn’t live in a GP’s office or a cluttered supplement aisle. It would be digital‑first, beautifully curated, and powered by data that actually helps you feel your best.

Build the Future of Wellbeing That’s what we’re building at Healf. An ecommerce platform at the intersection of personalised health and curated wellbeing. We connect customers with the world’s most effective products across EAT, MOVE, MIND, and SLEEP, and we’re just getting started.

We combine culture‑shaping storytelling, cutting‑edge health tech (like our new blood testing platform, Healf Zone), and a best‑in‑class product experience to help people build rituals that work.

Backed by investors behind Soho House, Alo Yoga, Cult Beauty, and Innocent, we’re scaling fast, and redefining how the world shops and lives well.

About Us At Healf, we’re not just a company, we’re a movement. Founded by two brothers whose own wellbeing journeys inspired our mission to empower others, Healf is built on grit, determination, and a shared understanding of the power of wellbeing.

Our culture is grounded in The Healf Standard—five principles that define how we work and win :

We Work Harder Than Anyone Else : Building something that improves lives takes long hours, grit, and sacrifice, but we thrive on it. We all feel energised by what we’re building.

Never Settle : We challenge the status quo and push ourselves to be better every day. We never settle for mediocrity or the idea that something can’t be done.

Obsession Over Talent : Talent alone isn’t enough — relentless curiosity and a drive to grow set us apart.

The Healf Lifestyle : We live what we preach—our personal commitment to wellbeing fuels our professional productivity.

Stronger Together : Everyone owns their lane, but we run as a unit.

With Healf Zone on the horizon, we’re entering the next phase of our journey : closing the loop on health with personalised, preventative care that unlocks longevity and optimised wellbeing. This is your chance to help build something that’s not only extraordinary, but a first of its kind.

The Role We’re looking for a Full Stack Engineer (Frontend Leaning) who’s obsessed with performance, craft, and creating joyful digital experiences.

You’ll help shape the future of Healf’s web experience — building and scaling our headless Shopify storefront and working closely with Product, Design, and Engineering to deliver beautiful, high‑performing interfaces that inspire trust and conversion.

You’ll take ideas from design to production, own the details of front‑end architecture, and play a key role in defining how our digital experience scales across the web and app ecosystem.

Where You’ll Make An Impact

Build and ship high-performance, production‑grade UIs and APIs with Next.js, React, TypeScript, and Tailwind CSS.

Implement modern data‑fetching (e.g., Server Actions, React Query, Next.js App Router) for speed, SEO, and scalability.

Integrate with Shopify Storefront / Admin GraphQL APIs and other third‑party systems (analytics, personalisation, etc.).

Translate Figma designs into reusable, accessible components, contributing to our design system.

Continuously optimise Core Web Vitals (LCP, CLS, FID) using performance audits, edge caching, and build‑time tuning.

Write and maintain automated tests (unit, integration, end‑to‑end) using Jest, React Testing Library, and Playwright.

Collaborate daily with Product and Design to prototype, test, and iterate fast.

What You’ll Bring

4 or 5+ years of experience building React front ends in production.

1+ years experience with Next.js and headless commerce (Shopify preferred).

Strong command of TypeScript, modern React patterns (hooks, server components), and Tailwind workflows.

Solid understanding of GraphQL queries, mutations, and pagination.

Deep care for UX and performance — you think in milliseconds and pixels.

Strong collaboration habits; you work well with design, product, and backend teams.

Nice to Have (Not Required)

Experience with PostHog or similar product analytics tools.

Exposure to A / B testing frameworks and data‑led iteration.

Familiarity with Vercel

Interest in AI‑driven personalisation or recommendation systems.

Why Join Healf

Do your life’s best work : Build something that matters, with a team that moves fast and aims high.

Surround yourself with A+ talent : You’ll work with high‑performers who care deeply and raise the standard every day.

Be a builder : This isn’t a cog‑in‑the‑machine role. You’ll help shape our voice, culture, and growth.

Wellbeing is the lifestyle : From office yoga to Healf Zone insights, everything we do is rooted in our pillars : EAT MOVE MIND SLEEP.
