Lead Product Designer (m/f/d)

About Hilo by AktiiaHigh blood pressure is the world's most common disease, causing 18M deaths each year. At Hilo by Aktiia, we're building a world where no lives are lost to its effects — with technology that helps people take control of their health.

We're a venture-backed scale-up with $96M raised from investors in Europe and the US. Rooted in 18 years of research at the Swiss Center for Electronics and Microtechnology (CSEM), our device is the world's only medically accurate, cuffless, continuous blood pressure monitor for daily use — clinically validated and CE Marked as a Class IIa medical device, now available in 12 countries. In July, we launched in the US.

We're a remote-first company headquartered in Neuchâtel, Switzerland, united by our passion for impact and innovation. Applicants must already hold a valid visa or work permit for their country of residence, as Hilo is not able to provide visa sponsorship.

Role overviewUX is our number one priority, and we need a design leader who consistently turns design into business outcomes. As Lead Product Designer, you set the quality bar for our app, own our design system and drive our biggest product bets from first idea to shipped result. You are hands-on: you prototype, you craft, you ship.

You will report directly to our Head of Design and work with product and engineering every day. You will be the design partner who keeps the whole product consistent and high quality, together with our Lead UX Writer and a Senior Product Designer.

You will have real ownership on a health product people use every day, in a business-critical, high-visibility role where UX is our top priority. You join a team with high talent density, people who raise your game, and a shared focus on speed, clarity and craft.

Location: Fully remote, open to candidates across the UK and Europe.

• Builder — You ship, and you can spin up something from nothing.
• Bias for action — You are autonomous and self-sufficient. You don't wait for a brief and you don't need chasing.
