Machine Learning Engineer

About us:

Layer Health is an AI startup spun out of MIT. We leverage LLMs to vastly improve the value and impact that can be unlocked from medical record data – building the “AI layer” for healthcare.

We know that all organizations in the healthcare ecosystem struggle to extract and synthesize insights from medical records at scale. Our AI layer radically speeds up and improves the quality of information gleaned from these records to power a wide range of impactful use cases– from research to quality measurement to clinical care pathways. Our team consists of world-class experts across machine learning, LLMs, medicine, engineering, and commercial execution. We are a Series A company headquartered in Boston, with offices in both Boston and NYC.

We’re seeking outstanding hires to join our team as early members. This is an opportunity to contribute to a high-impact, collaborative, mission-driven team, and help define the next stage of growth for Layer Health. Together, we will create the AI layer that will redefine healthcare for the better.

We’re hiring an exceptional ML Engineer to join our team (Boston or NYC office). In this role, you will design, develop, and deploy scalable ML software systems to address large-scale challenges in healthcare. You will work closely with our software engineers, research scientists, and product teams to build ML-native enterprise platforms, ensuring scalability, efficiency, and reliability.

You can expect to:

• Architect efficient, secure, reliable, and performant ML pipelines and infrastructure.
• Design, develop, and maintain scalable/data-centric backend infrastructure for our product.
• Translate start-of-the-art LLM research (both internally developed and from the community) into production, delivering value for our customers.
• Work with complex, large-scale, real-world clinical data (both structured and unstructured data) in a cloud-based environment.
• Develop methods and features to ensure high-quality results for our production models (methods to detect drift/performance degradation; develop observability tooling for performance characteristics, etc.).
• Collaborate with the broader product, engineering, and research teams to improve our products and build the next-generation of ML for healthcare.
• Build scalable infrastructure to ensure we can scalably support efficient model development and deployment pipelines, CI/CD, testing/experimentation.
• Ensure robust monitoring, logging, and error handling for deployed systems.
• Stay updated on the latest advancements in machine learning and AI.
• Cultivate a robust ML engineering and product culture that drives the company forward.

We look for:

• 3+ years of experience in building ML-native backend infrastructure.
• 5-7+ years of experience in backend and cloud platform software development, with the ability and flexibility to traverse the stack when necessary.
• Fluency in one or more backend programming languages including Python, Golang, Rust, Java (we use Python).
• Familiarity with modern ML/LLM techniques and frameworks.
• Bachelor’s degree in Computer Science, Engineering, Mathematics, or related field.
• Experience in 0-to-1 development of end-to-end ML systems (design, training, inference, deployment, and monitoring; bonus if involving LLMs).
• Experience developing and maintaining performant, scalable, and data-centric enterprise software products.
• Strong problem-solving skills and attention to detail.
• Excellent communication skills, with the ability to articulate complex technical concepts to non-technical stakeholders. 
• An excited and adaptable team player who wants to disrupt the healthcare industry with AI/ML, alongside an awesome team, in a customer-focused and fast-paced environment. 
• We are a Boston-based company, and expect engineers to meet regularly in-person in either our NYC or Boston office (engineers from Boston, NYC, or east coast are welcome).
