About Numan

Founded in 2018, we’ve already grown to be a 300+ team distributed across the globe, united by a singular mission: empowering people to take control of their health.

Numan is transforming health: we’ve built a cutting-edge platform that integrates diagnostics, medication, supplements, digital programmes, and doctor consultations. Giving people the tools they need to maximise life.

To deliver on our transformative mission, we are guided by our 5 company values:

• Patients first.
• Learn Fast.
• Own the quality.

• Care deeply.
  
  

Backed by top-tier investors, Numan is already having a positive impact on hundreds of thousands of patients here in the UK, and we want you to help us deliver this mission!

The role

Numan is evolving its platform into a personalised healthcare experience. At the centre of this shift is the Core Experience, which forms the foundation for every patient journey across our products and treatment pathways.

We’re looking for a Principal Product Designer to guide the vision and approach for the Core Experience. This is a strategic and hands-on individual contributor role, responsible for shaping the direction of design across the platform, strengthening quality, and helping develop how the design team works as it scales. You’ll work closely with the Design Director as a partner in thinking, supporting product vision, experience strategy, and the development of design practice at Numan.

You’ll be:

• Setting the direction for the Core Experience to ensure clarity, consistency, and ease of use across multiple products and journeys.
• Establishing design standards, frameworks, and patterns that enable the platform to grow in a coherent and sustainable way.
• Guiding and supporting designers by offering thoughtful feedback and helping refine their approach and craft.
• Working with colleagues across product, engineering, clinical, and research teams to shape priorities and explore options with evidence and insight.
• Using research, data, and iterative methods to inform decisions and measure outcomes.
• Helping strengthen design culture, ways of working, and collaboration across teams.
• Ensuring the Core Experience supports a range of treatment pathways while allowing specialist teams to contribute effectively.
  
  

We’re looking for someone who has:

• Extensive experience operating at Principal, Staff, or equivalent senior IC level in product-led environments.
• Experience shaping design across complex products or multi-team ecosystems.
• A strong foundation in systems thinking, platform-level UX, and designing for scale.
• The ability to work with senior partners across the organisation and influence the direction of work through clarity and reasoning.
• A supportive mindset, helping elevate the quality of design across teams.
• Strong capability across interaction design, visual design, information architecture, and service design.
• Experience applying research and data to refine and evolve design solutions.
  
  

It’s a bonus if you have:

• Experience working within healthcare or other regulated settings.
• Experience developing modular systems, reusable frameworks, or early-stage platform foundations.
• Experience helping evolve design practices or shaping team processes.
