Euc is the company behind Juniper, one of the world’s largest weight-management programs combining GLP-1 medication with personalised nutrition, movement support, and clinician-led care from prescribers, nurses, health coaches, pharmacists, and dietitians. Our published clinical research shows that our combined clinical and behavioural approach helps patients lose significantly more weight during their treatment with Juniper by four times.

Our Growth Story

• Received selective NICE endorsement to provide services to the NHS.
• Tailored our offering to thousand of patients in Germany and Japan

Shape Juniper and our expanding product ecosystem with fullstack impact

The Shop/Ecosystem squad is focused on expanding Juniper into new product lines and areas of care, helping patients discover the right products and services at the right time. One of the squad’s most exciting initiatives will be a recommendations tool, working in close collaboration with Data Science, to shape how patients interact with Juniper and other product lines across web and mobile.

Our stack: React, React Native, GraphQL Federation, Go, TypeScript, gRPC, Pub/Sub, Kubernetes, GCP

The impact you will have

• Implement scalable, maintainable solutions across frontend and backend, including features for the mobile app
• Contribute to engineering best practices and help mentor other squad members
• Partner with product, design, and other teams to prioritize what drives real impact

Who Succeeds Here

• Are experienced with backend development in Go, Node.js, or other languages
• Have experience with distributed systems and a balanced fullstack skillset
• Thrive in fast-paced, iterative environments
• Can work on complex systems and collaborate effectively across multiple teams

You don’t need to tick every box — if this role excites you, we’d still love to hear from you.

Nice to haves
