Usability Engineering Lead

Neko is redefining what prevention means, from treating illness when it arrives, to sustaining health before it's ever at risk.

Our mission: make data-driven, preventative care accessible to more people, before symptoms appear.

In a single, non-invasive visit under an hour, proprietary technology and direct clinical care combine to deliver personalised,

actionable insights. It's a team that thinks in 10x, not 10%. Every role here plays a part in building a world where prevention is

the norm, and where your work genuinely helps people live longer, healthier lives.

We're looking for an experienced Usability Engineer / Human Factors Engineer to drive usability engineering activities across Neko

Health's product development, and to lead the development of this domain within the Verification & Validation team.

You'll bring hands-on experience applying IEC 62366-1 to medical device product development, alongside proven experience

implementing usability practices that meet FDA human factors guidance. You'll work closely with the Usability & Validation

Engineers on the team to get design feedback into projects as early as possible, so that Neko's medical devices are safe to use.

• Usability engineering in product development: join product development projects as part of the usability engineering practice,

leading usability engineering activities on each project from early concept through final verification

• Domain leadership: grow the domain's capability and practice until it becomes a reference for best practice in a fast-moving

environment, constantly questioning processes without losing sight of purpose and user impact

• Process and practice: continuously improve how usability engineering integrates with product development, enabling it to run

alongside development. Build instructions, tooling, and training to efficiently support multiple development projects

• Design feedback, early: collaborate with Product, Design, Clinical, Engineering ,and other disciplines to integrate design

feedback in projects as early as possible, ensuring safety in use is designed in rather than tested later

• Formative and summative evaluation: plan, run, and document usability evaluations following IEC 62366-1 and FDA human factors

guidance, leveraging Neko's vertical integration for direct, in-house access to clinical personnel

• Design validation: oversee validation of UI-related user requirements and verification of use-related risk controls, ensuring

both processes are efficient enough to keep up with development without becoming bottlenecks

• Hands-on expertise with IEC 62366-1 usability engineering, including planning and conducting formative and summative

evaluations on medical devices and performing use-related risk analysis

• Experience with regulated medical devices, understanding how usability and design validation evidence fit into a technical file

or design history file under ISO 13485 and EU MDR

• Built or scaled a usability engineering practice by developing methods, tooling, or teams, beyond just executing individual

studies

• Comfortable working with both hardware and software; experience with medical devices that include hardware-software

combinations as well as software-only devices (SaMD), ensuring cohesive usability engineering across both

Usability engineering is core to how we build safe medical devices: it's the discipline that lets us say, with confidence, that

our products aren't just functional, but safe and easy to use. At Neko we want to keep challenging how we do things so we can move

faster, but never at the cost of safety or quality. As our product portfolio grows, we need a usability engineering practice that

grows with it, one that keeps pace rather than becoming the bottleneck. This role is driving how usability engineering at Neko

becomes a reference on integration of best practices into a fast-pacing and always innovating environment.
