Job description

We’re making good health last a lifetime.

More than 1 billion people globally live with obesity, a major leading indicator of many preventable chronic diseases such as diabetes and heart disease.

Eucalyptus is the company behind Juniper, one of the world’s largest weight management programs combining GLP-1 medication with a tailored nutrition and exercise programme for women, supported by our multidisciplinary care team of prescribers, health coaches, dietitians, nurses and pharmacists. More recently, we launched Compound, our men’s health brand dedicated to proactive, personalised healthcare solutions. Together with our other brands (Kin, Pilot, and Software), Juniper and Compound form part of our broader mission to solve the world’s biggest healthcare challenges by combining clinical care, science, and technology.

Our published clinical research demonstrates that our combined approach to weight management and lifestyle change means that our patients are 4x as likely to lose significant weight through their course of treatment with Juniper.

Since launching, we’ve grown fast to support millions of patients. In 2024 alone…

• In the UK we quadrupled the size of our business, received selective NICE endorsement for our holistic approach to obesity management, and grew our team from 45 to 165.
• Globally, we grew revenue by >120% YoY, while reducing cash burned by 90% YoY, with over $100M USD raised from global investors such as BOND, NewView, Blackbird and Airtree — early backers of companies like Canva, Stripe and Airbnb.

What’s next? In 2025, we are charting the path to support hundreds of thousands of patients while launching into new conditions, demographics, and geographies as we move towards our vision of creating a preventive healthcare ecosystem.

We’re going to build the world’s largest international digital healthcare company. This will be a challenging task, but it will be very rewarding and possibly the adventure of a lifetime, working with some of the best operators you will ever encounter. If that gets you excited, let’s talk.

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

About you (Who you are)

• Experience with React & TypeScript and proficiency in Node.js with GraphQL
• Experience working in iterative, data-driven teams
• Familiarity with digital product funnels and user journeys
• Around 4+ years of professional experience in engineering roles at startups or software companies
• Comfortable building web products with our tech stack
• Ability to break down projects, estimate timelines, and deliver high-quality work
• Clear written and verbal communication skills, including explaining technical concepts to non-technical colleagues
• Curious, problem‑solving mindset — excited to take ownership of challenges and help find the best path forward

Nice to haves:

• Exposure to Go
• Familiarity with data visualisation tools like Metabase or Tableau
• Experience in growth-focused roles at startups

So, why join Eucalyptus?

• Make real impact, fast – You’ll see your work influencing patient journeys immediately.
• Collaborate globally – Work with talented colleagues in London and Sydney, shaping solutions that scale internationally.
• Stretch your creativity – Work on open-ended challenges that demand inventive problem‑solving.
• Cross‑functional influence – Contribute to projects that intersect with growth, marketing, operations, and care teams.
• Accelerate your career – Regular feedback, reviews, and a personal development budget to help you grow quickly.
• Work with passionate peers – Our talent bar is high, our mission is ambitious, and our culture is supportive.

Benefits include:

• Equity through our employee options program
• Newly opened HQ in Old Street, designed for focus and collaboration
• Flexible hybrid setup: 3 days a week in-office
• Monthly wellness allowance
• Yearly personal development budget + 3 extra days leave
• 25 days holiday + bank holidays + enhanced parental leave
• 3 weeks per year “work from anywhere” policy
• Regular socials, sports, clubs, and seasonal parties (last year’s winter social was in Paris 🇫🇷)
• Your own MacBook and more!

At Eucalyptus, we value individuals from all backgrounds, experiences, and perspectives, and we embrace the unique qualities each person brings. When you apply, please let us know of any reasonable adjustments you may need during the interview process.
