About The Engineering Team
At ZOE, we use advanced science and technology to transform health—and our Engineering team sits at the heart of that mission. We are a distributed team of around 40 engineers across the UK and EU who thrive on solving complex challenges together.
We are a highly cross-functional group, bringing together front-end, back-end, mobile, machine learning, and data expertise. We partner closely with Product, Design, and Science to build truly impactful member experiences.
Our Values: We value curiosity, openness, and empowerment. We encourage continuous learning, sharing ideas, and shaping how we work—whether through experimenting with new technology or improving team efficiency.
We're proud of our team's diversity (44% female, 56% male) and believe that varied backgrounds, cultures, and lived experiences make us stronger, more creative, and better equipped to serve our global community.
About The Role & Impact
This role is crucial for building the scalable, high-quality services and robust data foundations that power impactful experiences for ZOE members. You will be instrumental in ensuring our platform is robust, performant, and ready to handle rapid growth and complex data challenges.
Your primary focus will be the design, development, and scaling of our core microservices and data pipelines. While your deep expertise lies in the back-end (Kotlin/Spring Boot or Python/FastAPI), you will contribute to the full-stack architecture, collaborating with specialists to integrate features seamlessly.
What You’ll Be Doing
Building and maintaining scalable backend services (microservices, data pipelines) with context on mobile experiences.
Collaborating closely with Product Managers and UX Designers to deliver elegant solutions that delight our users.
Breaking down complex problems into manageable pieces for incremental, high-quality delivery.
Writing clean, maintainable, and testable code that is designed for scale.
Shipping features to production regularly—ideally daily, or as often as possible.
Contributing ideas to improve team processes, quality, and overall engineering efficiency.
Our Technology Stack (A Taste of What You'll Use)
Backend: Kotlin / Spring Boot, Python / FastAPI & Django
Frontend: TypeScript, React Native, Next.js
Data & Messaging: dbt, BigQuery, Airflow, Google Pub/Sub
Infrastructure: GCP, Kubernetes, Terraform
Tools & CI/CD: Grafana, Firebase Auth, ArgoCD, GitHub Actions
We Think You Would Be Great If You…
This is what we believe can help someone thrive in this role.
3–5 years of experience in full-stack development, with a proven focus and deep expertise in back-end engineering.
Deep expertise in a modern back-end language (e.g., Kotlin, Python, or Java) and extensive experience building microservices and RESTful/gRPC APIs.
Experience with and a desire to work on scalable data technologies (e.g., message queues like Pub/Sub, or ETL/ELT tools like Airflow/dbt).
Working knowledge of a mobile framework (like React Native), sufficient to understand integration points and full-stack context.
Experience with cloud platforms (GCP preferred) and containerisation (Kubernetes/Docker).
A pragmatic approach to engineering—favouring simple, maintainable solutions over unnecessary complexity.
Comfortable working in a fast-paced, collaborative environment with some ambiguity.
Passion for building meaningful products that improve people’s health.
A team player who enjoys learning, sharing knowledge, and building positive working relationships.
