Help us build the future of mental health by developing our new AI Therapist

About Limbic

Limbic’s vision is to ensure the highest quality therapy is accessible to everyone, everywhere.

Limbic is already used in over 50% of Talking Therapies in the NHS in the UK as well as serving thousands of patients every week across the US, which makes us the largest-ever deployment of generative AI for direct patient care.

Our products augment clinical care, reduce barriers to accessing therapy at scale, and deliver autonomous mental health interventions, all deployed with safety as the top priority and as the only AI mental health chatbot with UKCA Class IIa and FDA TEMPO certification. Our company puts rigorous scientific quality first and our results are published in leading scientific journals, such as Nature Medicine.

The Role

As a Senior AI Researcher, you have demonstrated a deep expertise in AI research, in particular in the context of large language models (LLMs). In this role, you will drive innovation and dedicate your expertise to catapulting forward the capabilities of AI-delivered mental health therapy.

What You’ll Do

  • Use cutting-edge ML techniques to improve patient trajectories and outcomes.
  • Use existing data to identify meaningful mental health representation spaces.
  • Identify causal mechanisms driving recovery from mental health conversations.
  • Predict trajectories of mental health outcomes and build recommender systems for interventions.
  • Design and run rigorous scientific experiments to validate your methods and publish these in high-impact peer-reviewed journals.
  • Lead on patent submissions to protect intellectual property.
  • Work closely with the clinical research team as well as the ML engineering team to build product-ready, clinically evaluated tools.
  • Drive continuous improvement through experimentation, iterative development, testing and optimisation.
  • Translate complex scientific challenges into impactful solutions.
  • Mentor and guide junior scientists and colleagues, fostering a collaborative, high-performing team culture.
  • Present your findings in internal and external scientific meetings and events.

Reasons to use Rodeo

I’m in my final year doing Economics and I don’t know whether to apply for grad schemes now or do a masters first. What do you think?

Honest answer — it depends on where you want to end up. A lot of top grad schemes (Big 4, civil service, banking) don’t need a masters. Let’s look at the ones you’d be competitive for now, and we can decide if a masters actually adds anything.

Also worth knowing: most autumn 2026 applications are open now. Timing matters more than you think.

Start with a chat, not a search bar

Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
