YOUR MISSION

Join us to create the world’s best AI Therapist that will make conversational mental health care universally accessible, affordable and effective to anyone with internet access.

HelloBetter is a leading company in the emerging field of digital therapeutics (DTx) for mental health conditions. We are also a global pioneer in digital mental health research. Our scientifically validated DTx treatments cover a broad range of mental health disorders, including depression, panic, stress and burnout, insomnia, vaginismus, chronic pain and diabetes, alcohol addiction as well as two prevention programmes.

We recently entered a new era of technology, marked by the introduction of advanced AI systems using transformer architectures, alongside a rapid growth in computational capacities, potentially having an impact that could exceed that of the internet’s invention three decades ago.

With the growth in the number of patients using our products, HelloBetter has gained invaluable insights into how patients benefit from digital mental health programmes. Now, we deploy AI in order to leverage the insights we gained in +15 years of research, having treated +100k patients.

Ultimately, we aim to deliver on the promise that mental health is a human right: Do you want to be part of that mission?

YOUR OBJECTIVES

As the leading expert, you and our team of Machine Learning, LLM, and NLP experts, as well as world renowned psychologists and researchers will pioneer the development of our domain-specific Large Language Model (LLM) for mental health care:

1. Design and architect an AI system with multiple large language models, including a main conversational agent and supplementary models for contextual support.
2. Steer the fine-tuning of language models on specific healthcare domains to ensure high relevance and accuracy in model responses.
3. Implement a RAG system to augment the conversational agent with relevant external knowledge and context.
4. Develop and manage datasets, ensuring data quality and compliance with data privacy regulations.
5. Establish performance metrics to evaluate model effectiveness and system efficiency.
6. Collaborate with cross-functional teams, including data scientists, data engineers, software developers, and product managers, to integrate AI models into existing platforms.
7. Stay updated with the latest advancements in AI, machine learning, and related technologies, applying this knowledge to improve system capabilities.
