Role
Who you are
- ML Expertise: 4+ years of professional experience in Machine Learning, with a track record of deploying and maintaining LLMs in production
- LLM Proficiency: A deep understanding of LLM architecture and the orchestration of complex applications (e.g., Claude Code, Codex, OpenCode)
- Technical Stack: Proficiency in Python and SQL (TypeScript is a plus) alongside modern software development best practices
- Leadership: Proven ability to own ambiguous projects from ideation through maintenance, providing technical mentorship to peers
- Communication: The ability to translate complex technical concepts for both technical and non-technical stakeholders
Desirable
- Experience in fast-paced startup environments
- Background in post-training LLMs (SFT, RLHF)
- Familiarity with cloud platforms like GCP or AWS
- Previous AI research experience
What the job involves
- As a member of the Mind team, you will develop AI and ML solutions for our end-to-end mental health platform
- Our system manages complete care pathways, from initial assessment and intervention selection to continuous progress monitoring across various therapeutic domains
- Technically, we view Mind as “Claude Code for mental health.” In this role, you will help build and maintain our core agent, spanning the full AI stack: prompt engineering, memory orchestration, RAG, agentic workflows, and potentially, model fine-tuning
- Architect & Build: Contribute to designing, evaluating, and shipping our mental health AI Agent and its supporting infrastructure (including safeguards and system alerts)
- Data Strategy: Develop and maintain robust data pipelines to power model training and evaluation
- Collaborate: Partner with AI Research, Product, and Engineering teams to define new features. You will bridge the gap between Research and Engineering, making ongoing knowledge sharing vital
- Drive Innovation: Spearhead initiatives to integrate new AI/ML capabilities, navigating technical uncertainty and balancing time-to-value tradeoffs
Our take
For a number of reasons including cost, only about 30% of patients complete their physical therapy regimens. This results in millions of people not receiving the full breadth of care they need to reach full recovery. And physical therapy practices are missing out on a massive amount of revenue potential.
SWORD Health’s clinical-grade virtual therapy platform pairs physical therapists with FDA-listed wearable technology to deliver personalised treatment plans that are more effective, easier and less expensive than traditional physical therapy. This encourages patients to complete their regimes and allows practices to bolster their income.
The company works with international insurers, health systems and employers, with clients from the Fortune 100 and 500 lists. It is the fastest-growing MSK company and a double-Unicorn, now valued at $4 billion. With a rapidly growing US market, it's using impressive funding to continue its foundational AI model development and expand into ever more areas of healthcare.
