ABOUT THE ROLE:

How can we use vast amounts of proprietary and internet-scale healthcare data to build systems that enable access to significantly better health care? In this role as Principal Machine Learning Engineer, you will define and drive the architectural vision for large-scale, foundational machine learning models and applications that power care personalization, treatment intelligence, and automation at scale. Your work will directly impact every aspect of patient care, including but not limited to MedMatch, our AI-powered system that enhances provider-patient interactions, optimizes treatment recommendations, and expands into new verticals. This impact will be driven by architecting resilient, scalable, and extensible ML platforms that accelerate product development, unlock intelligent care delivery, and influence long-term ML strategy and engineering practices across teams.

YOU WILL:

Define and drive the architectural vision for ML and LLM systems that support treatment recommendation, personalization, and intelligent care delivery at scale
Establish foundational design patterns and infrastructure practices that ensure systems are scalable, resilient, secure, and maintainable
Work hands-on with Python and ML frameworks like PyTorch to prototype, optimize, and guide implementation of complex model pipelines and platform components
Align high-impact technical decisions with long-term product strategy by partnering with platform, product, and clinical teams
Architect and evolve robust ML infrastructure to support continuous training, real-time inference, evaluation, and observability
Lead cross-functional initiatives that simplify system complexity, improve developer velocity, and increase organizational leverage
Shape quality strategies across teams by defining standards for testing, observability, performance, and operational risk
Mentor senior and staff engineers across squads, supporting their growth as systems thinkers and technical leaders
Champion a culture of sustainable speed, system ownership, and architectural clarity across product and platform teams

YOU HAVE:

10+ years of experience in Machine Learning and/or Engineering, with a strong track record of technical leadership and system architecture across teams or business areas
Expert-level proficiency in Python and advanced ML frameworks such as PyTorch or TensorFlo
Demonstrated success in designing, scaling, and evolving ML platforms that support production-grade training, deployment, real-time inference, and monitoring
Deep experience in LLMs and NLP, including transformer models, summarization, conversational agents, and embedding-based retrieval
Advanced understanding of ML infrastructure, including continuous training, system observability, performance optimization, and platform reliability
Experience with ML infrastructure tools such as Databricks, MLFlow, SageMaker, or equivalent
A Master’s degree or PhD in Computer Science, Machine Learning, or a related field (not strictly required)
Exceptional communication and cross-org leadership skills, with the ability to align diverse technical and non-technical stakeholders around ML strategy and long-term architecture

OUR BENEFITS (THERE ARE MORE BUT HERE ARE SOME HIGHLIGHTS):

Competitive salary & equity compensation for full-time roles
Unlimited PTO, company holidays, and quarterly mental health days
Comprehensive health benefits including medical, dental & vision, and parental leave
Employee Stock Purchase Program (ESPP)
401k benefits with employer matching contribution
Offsite team retreats

We are committed to building a workforce that reflects diverse perspectives and prioritizes ethics, wellness, and a strong sense of belonging. If you're excited about this role, we encourage you to apply - even if you're not sure if your background or experience is a perfect match.
