The team blends deep medical expertise with advanced machine learning and product design, creating technology that is safe, reliable, and clinically validated. Their mission is to build tools that make healthcare more efficient, effective, and human.

The Role

We’re looking for a Senior AI / Machine Learning Engineer to design, build, and scale advanced language and machine learning systems at the core of the company’s clinical platform.

You’ll work closely with clinicians, product managers, and software engineers to transform complex healthcare challenges into robust, data‑driven solutions. This is a hands‑on role with broad impact—touching everything from model training and deployment to safety evaluation and infrastructure.

Key Responsibilities

• Design and implement NLP and ML systems for clinical and conversational applications
• Build and maintain data pipelines, model training, fine‑tuning, evaluation, and deployment workflows
• Collaborate cross‑functionally to translate clinical requirements into scalable technical solutions
• Ensure safety, performance, and regulatory compliance of ML systems
• Contribute to technical strategy, architectural decisions, and mentoring within the ML team

What We’re Looking For

• 4+ years of hands‑on experience in AI, ML, or NLP, ideally in a product setting
• Strong knowledge of large language models (LLMs), embeddings, fine‑tuning, and evaluation methods
• Advanced Python skills and experience with frameworks like PyTorch, TensorFlow, and HuggingFace
• Experience building full ML pipelines from data ingestion to deployment
• Solid software engineering practices including testing, version control, and CI/CD
• Strong communication and collaboration skills, especially with non‑technical stakeholders
• Interest in applying AI to healthcare or other high‑impact domains

Nice to Have

• Experience in healthcare, clinical AI, or medical data
• Knowledge of model safety, bias monitoring, or regulatory frameworks
• Familiarity with multi‑modal ML, retrieval‑augmented systems, or knowledge graphs
• Production experience with scalable ML systems
• Understanding of privacy and security considerations in regulated environments

Why Join

• Competitive salary and equity options
• Flexible, hybrid or remote working options
• A mission‑driven environment where your work directly improves patient care
• Collaboration with clinicians, product experts, and ML researchers
• Opportunities for professional growth, mentorship, and learning
