About Limbic

Limbic is the company behind the world's largest deployment of patient-facing mental health AI, having supported over 500,000 patients to date. We built the first AI diagnostic for adult mental health to be regulated as a Class IIa medical device, our work is peer-reviewed and published in leading journals, and we advise governments globally.

The role

We're hiring a Clinical Contractor for a focused, four-week sprint to accelerate the development of Limbic Care, our patient-facing CBT app. You'll be an experienced psychologist or psychotherapist, specialising in CBT, who can test, iterate on, and write the prompts behind the generative AI that delivers care to our patients.

This is a hands-on, fast-moving contract. Onboarding time is minimal - we need someone who can begin prompt writing and iterating on existing prompts almost immediately. Full support will be available to you throughout the working week, but you should be comfortable hitting the ground running from day one.

At a glance

Contract length: 4 weeks

Time commitment: 20 hours per week

Pay: £50/hour (UK) or $68/hour (US)

Location: Remote - must be resident in the UK or the US

Start date: As soon as possible (within the next week)

Hours: Flexible, including outside typical working hours - but with at least 4 hours per week overlapping the UK working day to attend meetings if required.

What you'll do

• Test and iterate on our current CBT interventions, as delivered by a generative AI chatbot - pressure-testing clinical content for quality, efficacy and safety.

• Create new clinical content from scratch, including writing prompts that direct generative AI agents to deliver CBT.

• Run clinical testing across various AI models to assure clinical efficacy and patient safety.

Essential requirements

• A clinician — psychologist or psychotherapist — with a qualification and extensive experience in delivering CBT.

• Registered/licensed with an appropriate regulatory body. For UK applicants, this must be the BABCP. US applicants must hold equivalent professional licensure.

• Experience working with or for an AI company, or extensive experience prompt engineering and testing clinical LLM conversations.

• Not currently working with or for another company that creates AI products for use in mental or behavioural healthcare (conflict of interest).

• Resident in the UK or the US.

• Able to start as soon as possible (within the next week) and able to begin prompt engineering with minimal onboarding.

• Fully available for the engagement: you must not have any periods of leave within the next month that would prevent you from completing 20 hours per week of work for Limbic.

• You do not need to be able to code or be proficient in any form of software engineering. We provide the UI which allows you to utilise your clinical and prompt engineering/writing skills.

Ways of working

You can complete your hours flexibly, including outside of typical working hours, provided at least 4 hours each week overlap with the UK working day so you can attend meetings. Onboarding will be light by design, but clinical and technical support will be available to you at all times within the working week.

Why this hire matters

The work you do over these four weeks will directly shape how Limbic Care supports patients - improving the clinical quality and safety of an AI that is already among the most widely used in mental healthcare.

Limbic is an equal opportunities employer. We welcome applications from all qualified candidates regardless of background.
