Senior Full-Stack Engineer

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 work on complex workflows that sit at the very core of how our patients access care. These workflows require creativity, experimentation, and structured problem-solving—you’ll balance building robust, scalable systems with tailoring local solutions that can flex to new regulations, clinical protocols, and user behaviours. 

You’ll also spend significant time working cross-functionally with teams outside of tech — including growth, marketing, and operations. Success in this role means being able to translate complex technical concepts into clear, non-technical language so that cross-functional partners can engage, contribute, and move quickly. Your ability to distill ideas will enable smoother collaboration, faster iteration, and better patient outcomes.

Here are some examples of recent UK team projects: 

• We developed a powerful patient segmentation model that classifies individuals into risk categories from their questionnaire data, enabling prescribers to deliver more precise and timely interventions to those who need it most.
• Right now, we’re focused on transforming our onboarding system so it can handle multiple flows and questionnaires, expanding our reach and making it possible to connect with more patients than ever before.

Expect to:

• Run structured, data-informed experiments to improve the UK market’s conversion funnel
• Extend the core platform to better serve UK-specific customer journeys
• Prioritise 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 high-leverage touchpoints
• Collaborate with Australian product teams to co-develop scalable global solutions, while advocating for UK market needs
• Partner closely with non-technical teams to align on strategy, translate engineering work into actionable insights, and accelerate delivery

This is not a role for surface-level optimisation — it’s about creative, insight-led engineering that makes healthcare simpler, safer, and more accessible.

• Strong React & TypeScript experience and proficiency in Node.js with GraphQL.
• Experience working in highly iterative, data-driven teams.
• Understanding of conversion funnel optimisation in a digital product.
• At least 6+ years of experience in a similar role at other startups or software companies under your belt.
• Experience building web products with our tech stack.
• Proven record of successfully breaking down projects, estimating timelines and consistently delivering high-quality work.
• Excellent written and verbal communication skills, with the ability to clearly explain technical concepts to non-technical audiences.
• You’re naturally curious and enjoy understanding how things work. Your problem-solving mindset is key here — you’ll have the autonomy to take ownership of challenges and determine 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.
