Software Engineer II, UK

About Eucalyptus

We’re on a mission to make good health last a lifetime. More than 1 billion people live with obesity worldwide, driving preventable chronic conditions. We’re here to build better long-term care.

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. Compound, focused on longevity and preventive health, complements this ecosystem and extends our mission to make good health last a lifetime.

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:

130% YoY revenue growth and a 90% reduction in cash burn, with $100M+ raised from investors including BOND, NewView, Blackbird and Airtree.
Scaled to over 100,000 monthly active patients across our weight-management program.
Grew the UK patient base from 4,000 to ~40,000 and received selective NICE endorsement to provide services to the NHS.
Tailored our offering to over 5,000 patients in Germany and Japan

About the role (What you’ll be doing)

This role is part of our growing UK engineering team, working in close partnership with our platform and product teams in Australia. The UK team is focused on locally prioritised initiatives that respond to patient needs and market dynamics. Being embedded in the UK allows us to stay close to the challenges and opportunities unique to this market — enabling us to refine and extend the platform in ways that drive meaningful, sustained outcomes.

As part of this team, you’ll contribute to workflows that sit at the very core of how our patients access care. These workflows require creativity, experimentation, and structured problem-solving—you’ll help build robust, scalable systems while tailoring local solutions that can flex to new regulations, clinical protocols, and user behaviours.

You’ll also work cross-functionally with teams outside of tech — including growth, marketing, and operations. Success in this role means being able to communicate technical concepts in clear, non-technical language so that cross-functional partners can engage, contribute, and move quickly.

Examples of recent UK team projects include:

Developing a patient segmentation model to classify individuals into risk categories from questionnaire data.
Transforming our onboarding system to handle multiple flows and questionnaires, expanding reach and patient access.

Expect to:

Execute data-informed experiments to improve the UK market’s conversion funnel
Extend the core platform to better serve UK-specific customer journeys
Contribute to initiatives that create real business impact, not just vanity metrics
Improve retention and repeat order rates through localised product improvements
Deliver polished, seamless front-end experiences across key touchpoints
Collaborate with Australian product teams to co-develop scalable global solutions, while advocating for UK market needs
Partner with non-technical teams to align on strategy and accelerate delivery
