_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.

We are looking for a Senior Frontend Engineer to contribute to our mission of improving patients' health and their lives.

To us, it’s more than just strong technical fundamentals. We're looking for someone who brings deep engineering skills and a strong sense of product ownership.

This is a remote role based in Brazil — you'll be part of a globally distributed mission-led team with engineering hubs in London, Sofia, and São Paulo.

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’ve 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 its safe to take shortcuts.

What You Will Do

Extreme 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.

Job Requirements

At least 5 years of commercial experience as a software engineer or equivalent
Frontend craft – Strong experience with React/Next.js or React Native, 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
Excellent English skills (verbal and written) are mandatory
