Senior 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. As a Series B scale-up, we are investing heavily in the product experience, and you will be central to it. You will own our biggest new product bets: new features, health insights and early vision work across the app. You will bring ideas to life fast, with polished high-fidelity prototypes and motion, then take them to a shipped result.

You will report directly to our Head of Design and work with product and engineering every day. Alongside you are a Lead Product Designer and a Lead UX Writer, who keep the whole product consistent and high quality.

You will have real ownership on a health product people use every day, in a business-critical 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

Ownership & Outcomes

• Own your product areas from first idea to shipped result.
• Set the measures for your work and own whether it succeeds.
• Turn research, feedback and data into clear decisions.

Prototyping & Design

• Spin up working prototypes with AI tools and our design system, not just static screens.

Collaboration & Continuity

• Work daily with design engineers and product managers, and unblock them fast.
• Take over existing product design work and keep quality high.

Requirements

Background & Experience

Essential

• Senior product design experience, ideally in health, consumer, behavior change or regulated products.
• 1 to 3 shipped case studies that show the problem, your role, your decisions and the measurable impact.
• Strong UX and UI craft: visual hierarchy, typography, motion and attention to detail.
• High-fidelity prototypes you can screen-share and walk through (Figma, AI tools such as Claude or Lovable).
• Daily, practical use of AI tools, and enthusiasm for trying new ones.
• Fluent Figma, including components, variables and tokens.
• Close work with engineers, and clear, short communication.
• A public portfolio website (required with your application).

Nice to Have

• AI-ready design systems, mobile apps, connected devices, simple prototypes in code.
  

How you work

• AI first — You'd rather show a working thing than describe one.
• Builder — You ship, starting from nothing if you have to.
• Bias for action — You don't need to be told what to do or be chased. You spot what could go wrong, pick the one that matters most and fix it.
• Disciplined — Tokens, not screenshots. Decision logs, not memories.
• Curious — You want to know why, not just what.
• Clear under pressure — Medical regulation and different market rules are design problems, not excuses.

This isn't for you if

• You need a finished brief, all the requirements or all the research 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)
3. Product thinking and interaction design deep dive
4. Cross-functional conversation with design engineers and product
5. Final conversation with senior leadership

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.
