Clinical AI Scientist, 9 month FTC (Part-time, 4 days)

The Role — Clinical AI Scientist

Nova is Unmind's AI wellbeing coach and the centre of our product offering. Its value to clients depends on it being demonstrably effective, safe, and continually improving. We're hiring a Clinical AI Scientist to join a small, ambitious clinical AI function and drive the day-to-day clinical work behind Nova's in-product measurement, safety, and structured experience programmes.

What you'll do
• Drive the day-to-day clinical delivery of how we measure user outcomes inside Nova at scale, in close partnership with our research and data science functions.
• Help shape the clinical design of Nova's structured wellbeing experiences, including the safety architecture that sits underneath them.
• Run the day-to-day evaluation, rubric, and safety-testing work that helps govern Nova's clinical quality, from gold-standard responses to red-teaming and escalation protocols.
• Contribute to peer-reviewed publications, whitepapers, and the clinical evidence base that supports Nova.
• Partner with Product, Engineering, Data, Commercial, InfoSec, and external academic partners to embed evidence-based thinking in how Nova is built and governed.
About You

In the spirit of equity and continuous growth, we invite you to remove education from your CV. Qualifications are not a factor in our decision-making. However, some experience in the following is important for this position:

Essential
• A doctorate in clinical, counselling, or health psychology (DClinPsy, DCounsPsy, DHealthPsy, or a clinical psychology PhD), with current HCPC registration – or an equivalent route into clinical practice, including qualified clinicians without a doctorate.
• Demonstrable experience in clinical risk assessment and management, gained through clinical placements, post-qualification practice, or equivalent settings.
• Demonstrable fluency in evidence-based behaviour change, coaching, and psychological frameworks (e.g. ACT, FACT, third-wave CBT).
• Experience translating these frameworks into structured artefacts that others can put into practice (e.g. AHPs, peer supporters, coaches, product and engineering teams).
• Exceptional written and verbal communication, with the ability to translate clinical thinking for product, engineering, and scientific audiences.

Strongly desirable
• Hands-on experience with LLMs in a clinical or mental health context: prompt design, rubric and evaluation design, and structured clinical testing.
• Psychometric or computational methods experience – instrument validation, item response theory, latent variable modelling, LLM-as-judge evaluation design, or peer-reviewed measurement work.

Nice to have
• Working proficiency in Python and/or R with SQL, and/or exposure to red-teaming or safety-evaluation methods for human-facing AI.

Tip for candidates: If you're unsure whether to apply – do. We know great people don't always tick every box.
