Senior UX Designer - Freelance (Paris)

Senior UX Designer - Freelance (Paris)

We are HealthHero, Europe’s largest digital clinic. Join us at a pivotal moment as we scale our digital healthcare platform across Europe and help shape the experiences at the heart of a fast-growing, AI-driven business.

We are looking for an experienced Senior UX Designer for a 6-month freelance mission at 80% (4 days per week), starting as soon as possible. The mission is hybrid, with around two days per week in our Paris office, working with our UK, France and Ireland markets. Fluent English is essential to express your ideas and work with native speakers.

The mission

You will own one of our key user-facing product experiences end-to-end and become the go-to expert on that product: its users, its clinical and operational context, and what is technically possible. You will work in an AI-first way, using a robust design system and coding agents to go from insight to shipped experience, delivering on time and to a high quality bar.

Own a patient-facing product end-to-end

• Take ownership of one of our key patient-facing product experiences, from research and stakeholder management through to design.

• Handle feedback, testing and deployment handover for that product experience.

• Build in-depth knowledge of the product, its audience and its technical capabilities.

• Run the right research and testing to make evidence-based decisions, then design clear, usable and accessible solutions through to handover.

Deliver with quality and on time

• Manage stakeholders on the product and deliver on time to a high-quality standard.

• Move fast from a light brief to MVP concepts using expert judgement, then iterate continuously.

• Bring a strong craft bar to every surface: interaction, visual and content design that is clear, cohesive and on brand.

• Design to accessibility standards (WCAG) and with clinical safety in mind, given the patient context.

• Apply the design system and contribute to its enrichment.

Work AI-first

• Use and champion an AI-first workflow built on a robust design system and coding agents.

• Design with system components by default and contribute new patterns back to the design system.

• Use coding agents to move efficiently from design to production-ready front-end.

Collaborate and expand what’s possible

• Work with product owners to define the functionality of each product, while expanding their understanding of what is possible.

• Partner closely with engineering, clinical and operations colleagues, surfacing risks early and shaping feasible, valuable solutions.

• Take part in design critiques, reviews and knowledge sharing, giving and receiving clear, constructive feedback.

Profile

Essential

• Several years of product / UX design experience, with a portfolio showing end-to-end product thinking, from concept to shipped product.

• Strong craft across interaction and visual design, and the ability to work fluently within a design system.

• Confidence running user research and usability testing, and translating findings into design decisions.

• Fluent English.

• Excellent communication and stakeholder skills: able to align partners, challenge constructively and secure buy-in.

• Systems thinking, taking into account the overall impact of decisions on multiple stakeholders.

• Self-motivation and resilience in a fast-paced, evolving environment.

• Genuine enthusiasm for AI-assisted and code-aware design workflows.

Tools / stack

Figma, our design system, AI prototyping tools / coding agents, user-testing tools.
