Create concepts and functional prototypes using AI-assisted coding tools to explore behaviours, test assumptions, and support product decisions.

Conduct concept-validation sessions and usability tests with Research Ops support. Test user understanding, task success, and recovery when things go wrong, and use findings to improve designs.

Deliver detailed UI and interaction designs, including how people guide, review, and correct AI agents. Apply existing design-system patterns and contribute improvements where needed.

Work closely with developers through implementation and conduct design QA to improve usability and experience quality.

Communicate decisions clearly, share work in progress, and own defined problems with guidance while collaborating on more complex challenges.

Qualifications:

Around 2–5 years of relevant product design experience and a design degree or equivalent practical experience.

Strong UX, interaction, and UI design skills, with experience using design systems.

Hands-on experience using AI in research and design workflows and building functional prototypes with AI-assisted coding tools.

Experience validating concepts, testing usability, and collaborating with product managers and developers.

Initiative, comfort with ambiguity, and willingness to challenge assumptions and learn from feedback.

Clear written and spoken English, with the ability to articulate ideas and explain design decisions.

Preferred

Skills:

Experience designing AI-powered or human–agent experiences.

Experience with B2B SaaS, enterprise software, cloud platforms, deployment, operations, or governance.
