Senior Full Stack Engineer (FE Focused)

At ZOE, we're on a mission to empower people with the most advanced science and technology to transform their health.

Our Engineering team sits at the heart of that mission. We’re a ~40 distributed team across the UK and EU, who thrive on solving complex challenges together. We bring a wide mix of skills — from front-end, back-end, full-stack, and mobile engineering to machine learning, data science, and analytics — to build the experiences that guide our members through their health journey.

We’re proud of the diversity in our team: 39% female and 61% male, with colleagues from many different backgrounds, cultures, and lived experiences. We believe this diversity makes us stronger, more creative, and better equipped to serve our global community.

Collaboration is core to how we work. Engineers at ZOE partner closely with data scientists and analysts, product managers, and product designers to bring new ideas to life. Depending on the project, we also work hand-in-hand with marketing, finance, legal, and other teams, making our work highly cross-functional and impactful.

Above all, we value curiosity, openness, and empowerment. We encourage everyone to share ideas, learn continuously, and shape how we work — whether it’s through experimenting with new technology, improving our ways of working, or finding better ways to support our members.

We’re looking for a Full-Stack Engineer (Front-End Focused) to help us build world-class digital experiences. While ZOE maintains a full-stack environment, this specific role is designed for someone who is passionate about crafting seamless, performant, responsive and beautiful user interfaces across web and mobile.

You will spend the majority of your time in TypeScript, React, and Next.js, but you’ll also dive into our backend services (Kotlin or Python) to ensure the data you need is available, structured correctly, and delivered efficiently. You will contribute to shape and grow our web design system, collaborating closely with design and engineering. You will be launching A/B tests and will collaborate with analysts to interpret results.

💻 Our Stack

• Backend: Kotlin / Spring Boot, Python / FastAPI & Django

• Frontend: TypeScript, React Native, Next.js, GraphQL

• Tools: GTM, Headless CMS, Optimizely, Google Pub/Sub, Grafana, Firebase Auth,

• CI/CD: ArgoCD, GitHub Actions

• Data: Web data layer, dbt, BigQuery, Airflow

• Infrastructure: GCP, Kubernetes, Terraform, Vercel

• Developing a best-in-class, beautiful website that is fully performant and on-brand.

• Bridging the Stack: Collaborating on API design and occasionally implementing backend changes to support new front-end functionality.

• Design Partnership: Working hand-in-hand with UX Designers to turn high-fidelity mocks into fluid, accessible, and performant components.

• Engineering Excellence: Writing clean, testable code and contributing to our shared component libraries and design systems.

• Rapid Iteration: Shipping to production regularly (ideally daily) and using data/feedback to refine the user journey.

• Growth: Supporting and learning from senior engineers while mentoring others as you grow into a technical owner.

• Have 3–5 years of experience in software development with a heavy focus on the front-end.

• Possess Deep Expertise in TypeScript, React, and Next.js. You understand state management, hooks, and how to optimize for web performance.

• Have Working Knowledge of a backend language (like Python, Kotlin, or Java) and feel comfortable navigating an API or database schema.

• Are a Pragmatic Engineer—you favour simple, maintainable solutions over "clever" over-engineering.

• Thrive in Collaborative Environments and enjoy the "why" behind a product feature just as much as the "how."

We value your time as much as our own. We’ve designed a streamlined, 4-step process to get us from "Hello" to "Welcome to the team" as quickly as possible.

Step 1: 👋 Intro chat with Talent Team

A high-energy intro to see if our missions align. We’ll chat about your journey, what makes ZOE tick, and make sure the basics (role, impact, and expectations) are a match.

Step 2: 🧠 Hiring Manager Interview

A tactical conversation focused on your craft. We skip the generic scripts and dive straight into how you solve problems, your past wins, and the specific challenges this role is here to tackle.

Step 3: 🔄 The Remote Loop This is where we get into the details. Depending on the role and level, this stage consists of 2 to 4 focused interviews designed to assess different areas (e.g., technical skills, cross-team collaboration, or strategic thinking).

Step 4: 🎉 The Finish Line (Offer & Onboarding) If there’s a match, we don’t hang around. We’ll extend an offer, talk through equity and benefits, and get you ready for your ZOE onboarding journey. Let’s change the world’s health together.

The experience, skills, and attributes we’ve outlined are what we believe will help someone truly thrive in this role.

However, we understand that talent comes in many forms. If you are genuinely excited about ZOE's mission and this opportunity, please don't hesitate to apply—even if you don't meet every single requirement listed.

We fundamentally value potential and commitment above all else. We are dedicated to fostering growth and providing opportunities for you to learn and develop alongside us.
