Company mission
Voy is redesigning healthcare from the ground up. Founded in 2022 with a focus on weight loss, Voy rebranded from MANUAL in 2025 to expand into a broader range of health categories – including hair loss, testosterone and menopause (with more to come)
Role
Who you are
- 5+ years of frontend engineering experience with strong software fundamentals
- Deeply experienced with TypeScript, React Native and Expo
- Takes full ownership of projects and sees them through to measurable impact
- Product-minded: cares about UX, user outcomes and craft — not just code
- Comfortable operating in ambiguity and making sound technical judgement calls
- Pragmatic and execution-focused — you ship, iterate and improve
- Experienced in fast-moving consumer startups, scaleups or design-focused teams
- Confident using AI tools thoughtfully — accelerating output without compromising engineering quality
What the job involves
- You’ll join the core product engineering team responsible for building and scaling our Expo / React Native app
- This is not a ticket-taking role. You’ll own major mobile features end-to-end, influence architecture and product direction, and help shape how thousands (and eventually millions) of people understand and improve their health over time
- If you care about craft, autonomy, and building something meaningful — this is a rare chance to do all three
- Own major mobile features end-to-end in our Expo / React Native app, from concept to production
- Collaborate closely with product and design to shape UX, technical architecture and delivery strategy
- Make product and engineering decisions, not just implement predefined specs
- Drive improvements in app performance, reliability and maintainability as we scale
- Architect scalable patterns for state management, API integration and offline-first experiences
- Champion high engineering standards: testing, observability, code quality and thoughtful reviews
- Use AI tools responsibly to accelerate development while maintaining quality and correctness
- Ship high-quality features independently, with minimal oversight, in a fast-moving environment
Salary benchmarks
Our take
In 2019, Voy launched MANUAL because men's health was being ignored. Hair loss, low testosterone, sexual health... people suffered in silence or waited years to address these conditions. MANUAL set out to change that with earlier access to specialist care and zero stigma.
A few years later, they launched Voy for weight loss. But quickly learned something important: health doesn't stay in one box. So members moved between categories as their needs evolved and operating as separate brands no longer made sense for the company (or you).
So in 2025, the two companies became one, and is now Voy! Today, it supports over 1M members across the UK, Germany and Brazil, offering specialist led care across weight loss, menopause, TRT, hair loss and dermatology, alongside preventative health designed to help people stay ahead of illness, not just treat it.
Now the company is heading toward one mission: making 100 healthy years feel possible, supported and totally normal
