Lead Product Designer (m/f/d)

About Hilo by Aktiia

High 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 overview

UX 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.

Core responsibilities

Direction & Outcomes

• Set the design direction and quality bar across the app, from new features to health insights and early vision work.
• Define the success measures for your work and own the business results.

Design System & Prototyping

• Own our design system, built to work with AI tools, and keep it consistent through tokens and clear decisions.
• Show instead of tell, with high-fidelity prototypes and motion built with AI tools and our design system.

Leadership & Collaboration

• Raise the bar for the team. Support, coach and unblock other designers, and give clear feedback.
• Challenge product and engineering with evidence, persuade stakeholders and make clear, documented decisions.
• Work daily with product managers and design engineers.

Background & Experience

Essential

• Proven design leadership, with a track record of consistently delivering strong business outcomes.
• 2 to 3 shipped case studies that demonstrate high impact: the problem, your hypothesis, your decisions, the measured result.
• Outstanding visual design craft: hierarchy, typography, motion and attention to detail.
• High-fidelity prototypes and videos of your work, ideally built with AI tools such as Claude or Lovable.
• Daily, practical use of AI tools and experience with AI-ready design systems.
• Fluent Figma, including components, variables and tokens.
• Strong product thinking: you work with data, hypotheses and measurements.
• Ideally health, consumer, behavior change or regulated products.
• A public portfolio website (required with your application).

Nice to Have

• Mobile apps, connected devices, simple prototypes in code.

How you work

• AI first — You are already playing with AI tools and you are excited about what they make possible.
• 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.
• Disciplined — Tokens, not screenshots. Decision logs, not memories.
• Curious — You want to know why, not just what. You can explain who made each decision and how.
• Clear under pressure — Medical regulation and different market rules are design problems, not excuses.

This isn't for you if

• You need all requirements, research and data before you start.
• You measure screens shipped, not outcomes moved.
• You'd rather list risks than own one.

How we hire

1. Recruiter screen (30 min)
2. Portfolio interview with the Head of Design (60 min): visual craft, prototyping, AI fluency
3. Product thinking and interaction design deep dive
4. Cross-functional conversation with design engineers and product
5. Final conversation with senior leadership (finalists)

What success looks like

• You take something off our plate and it gets done.
• If it won't happen, you tell us first.
• You bring the problem, the root cause and options.
• You flag risk to dates early, while we can still change it.
• The product feels consistent, fast and high quality, and design outcomes show up in the numbers.
