Help us build the future of mental health by developing our new AI Therapist for end-to-end care in the US.
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, which makes us the largest-ever deployment of generative AI for direct patient care. Using Limbic Access we augment clinical care and reduce barriers to accessing therapy at scale - deployed with safety as the top priority and the only AI mental health chatbot with UKCA Class IIa certification.
Limbic is live in the US, interacting with thousands of patients there every week. Furthermore, we are launching an AI therapist doing end-to-end care in the US, and we are looking for a mission-driven engineer to help us build this critical new product.
The Role
As a Clinical AI Engineer, you will sit at the intersection of computational psychiatry, clinical science, and software engineering. You will drive the development of AI interventions that engage users, predict recovery milestones, and orchestrate evidence-based therapeutic sessions. This role is specifically focused on building and refining our end-to-end care AI therapist for the US market.
What You’ll Do
Drive effective session orchestration and lead the implementation of our Evidence-Based Intervention Library.
Develop AI features tailored for product retention and engagement.
Implement features involving expectation setting, gamification, and reinforcement learning for the personalization of care.
Optimize our recovery data collection processes, focusing on the methods, timing, and predictive modelling of PHQ-9s.
Provide occasional analysis and modelling support for additional clinical research projects.
