Senior Front End Engineer - London
MANUAL is a fast growing Healthtech scale-up, aiming to be the healthcare provider that millions of people trust as their partner to a long and healthy life. Our platform allows users to quickly and safely diagnose possible conditions, get treatment and support them afterwards to live a higher quality life. To do this we are building an all in one healthcare platform which brings together world leading medical expertise and technical excellence.
You will be joining one of our teams focused on building out our web app for patient onboarding and treatment management. This is a fast growing and exciting area in our business, focused on increasing retention and building out beautiful experiences that encourage and promote a healthy lifestyle. Our stack is based on Next.js and we are looking for people who have experience developing in the React ecosystem.
Who you are
Empathy for the user – You care about patients having an exceptional experience. You spot clunky flows and poor UX, and are motivated to fix them.
Data-driven – You are familiar with user analytics, feature flagging and observability tools. You default to data to guide your decision making.
Cross-functional partner – You work closely with PMs, designers, and analysts to make decisions and shape the product together.
Team contributor – You care about clean code, good reviews, and helping others grow. You lead by example, not just title.
End-to-end ownership — You don’t just ship code; you take full responsibility for what you build. You care about the why, not just the what, and you're just as comfortable in technical discussions as you are exploring user needs, product trade-offs, and impact.
Bias for action - You agitate for change, to try new approaches and are an ambassador for innovation. You are willing to go outside your comfort zone to solve a problem quickly.
First principle thinker - You can take a step back and think about problems holistically. You challenge assumptions and know when it’s safe to take shortcuts.
What you will do
Complete Ownership – You’ll lead the full lifecycle of features: from understanding the problem and sketching out rough ideas, to building it, shipping it, and measuring how it’s performing.
Drive & shape the future of our architectural vision. Helping us scale, move fast and onboard quickly.
Craft clean, efficient code that’s built to last. Holding high standards for yourself and your peers.
Create beautiful experiences that users can rely on. Utilising your eye for detail and the latest design ethoses.
What we need from you
Approximately 4-7 years experience as a Software Engineer
React experience isn't essential but is advantageous.
Frontend craft – Strong experience with React, Next.js, TypeScript, modern state management, performance tuning, etc.
Comfortable across the stack – You’re not afraid to write a backend route, shape an API, or dive into cloud infra when needed.
Great verbal and written communication skills and the ability to explain complex ideas in a simple way to non-engineering teammates

About Voy
Healthcare is broken. We’re fixing it — and we need your help.
Back in 2019, we launched MANUAL to to tackle men's health (starting with hair loss and sexual health). A few years later, we launched Voy with a focus on weight loss. But our ambition has always been bigger. Healthcare too often treats conditions in isolation, not people as a whole, and we're on a mission to prove there's a better way.
In 2025, we evolved from MANUAL into Voy, a brand built for the long game: supporting people through every stage of life, not just a single diagnosis. Today, we support over 1 million members across the UK, Germany and Brazil, delivering personalised care across weight loss, menopause, hair loss and TRT (with more categories on the way).
Ready to join us and change how healthcare feels for millions of people?
