About Ketryx:

Ketryx is an AI software platform that enables healthcare life sciences companies to ship life-saving regulated products in weeks instead of years.

Exploding product complexity is burying companies in compliance paperwork and blocking innovation. Our AI software removes this friction, dissolving the historical tradeoff between innovation and compliance, and enables regulated industries to innovate at the pace of modern software.

Just two years since launch, Ketryx already touches the lives of 25M patients and powers 3 of the world’s top 5 MedTech companies and 25% of the Fortune 500 MedTech market. Backed by Lightspeed Ventures, our founders are the former Head of AI at Amgen and CTO of Wolfram Cloud.

Healthcare and life sciences is just the beginning for us. Automotive, aerospace, energy — if it’s regulated, it’s because society decided it matters. These products move humanity, shape our future, and are safety-critical. Come join us and help build the AI platform to power safe innovation.

About the Role:

As Head of Design at Ketryx, you'll lead a small, highly motivated team of UI/UX designers and own the design strategy for our platform. You'll set direction, ship high-quality designs, interactions, and prototypes, and steer projects from concept to launch.

You'll work end-to-end on UI/UX — partnering closely with engineers, product managers, and executive leadership to ensure designs are intuitive, technically sound, and aligned with business goals. You'll lead the team while staying hands-on: creating UX flows, prototypes, and high-fidelity visuals yourself. Your work will directly support Ketryx's mission to help medical device manufacturers bring life-saving innovations to market faster and more safely.

This is a hybrid role requiring at least four days per week on-site in Vienna or Boston, with regular travel between the two offices.

Responsibilities:

You're an experienced UI/UX designer with a deep passion for software and a track record of shipping exceptional user experiences. You're equally comfortable thinking about design, product, and business — and you're motivated by the opportunity to improve patient outcomes through better technology. You set the UX vision and work cross-functionally to turn it into intuitive, user-centered solutions. You communicate clearly in English, both written and spoken, and you thrive in environments where ideas move fast.

You're a self-starter who does well in early-stage startups, balancing team leadership with hands-on design work. You embrace AI as a core part of how modern products — and modern design teams — are built, and you bring that mindset to your craft.

Ideally, you're based in Vienna or Boston, or ready to relocate quickly. Unfortunately, we're unable to sponsor immigration visas at this time.

• Managing and growing a team of designers and design projects
• Collaborate closely with product managers and developers to shape features
• Develop features from concept through prototype to developer handoff
• Meet with users virtually and in person for discovery work and design reviews
• Regular travel between Boston and Vienna (approx. 1 week every 6 weeks)

Required Skills:

• 8+ years of industry experience designing software user interfaces and workflows
• Prior experience managing a team of designers
• Prior experience with designing web apps and design systems
• Ability to quickly demonstrate product knowledge
• Ability to think through complex interaction design
• Hands-on UI and UX design work
• Experience with prototyping in Figma and with AI

Preferred Skills:

• Prior experience in a regulated industry
• Degree in design or user experience
