Staff Engineer, ML

Who we are:

Founded in 2016, K Health's mission is to deliver accessible, high-quality healthcare at scale. As a leading clinical AI company in primary care, K Health has developed a suite of clinical AI agents that enhance provider efficiency and improve patient outcomes. K Health's virtual primary care platform is enhanced by an AI copilot to complete the initial patient intake, summarizing relevant history from the EMR, and generating "the perfect note" to reduce the time providers spend on basic data collection and non-clinical tasks. Unlike other virtual medicine companies, K Health delivers comprehensive, longitudinal primary care in a virtual setting, enabling our clinicians to be true primary care providers without sacrificing scope of practice or continuity of care.

As a venture-backed startup trusted with nearly $400 million in funding and a $900 million valuation as of July 2024, K Health is well-positioned for sustained future growth. We are expanding our partnerships with major health systems (Cedars-Sinai, Hackensack Meridian Health, Hartford HealthCare), enhancing accessibility and quality of care by pairing people with technology. Our providers are credentialed at these renowned academic health systems and adhere to their clinical guidelines, ensuring patient-first, evidence-based care. Fully integrated into Epic, our AI platform enables K Health to operate as an extension of existing healthcare systems, benefiting from a built-in network of specialists and social services to seamlessly serve patients within those communities. Our unique care delivery model enables our providers to deliver the same high-quality, accessible care to a mixed-payer population, including those with commercial insurance, Medicare, and Medicaid.

Join us in our mission to deliver smarter, simpler healthcare of the future - today!

About the role

We are looking for an experienced ML/AI engineer to anchor our ML Platform team. You will lead the effort to productize our Large Language Models, transforming experimental code into robust, efficient services. Your goal is to build the infrastructure that allows our Data Scientists to move fast without breaking production.

What you'll be doing:

Model Development & Optimization

Fine-tuning & Engineering: Develop and fine-tune LLMs/classic models for specific medical tasks (condition detection, dialogue systems) using internal datasets.
Research to Production: Partner with Data Scientists to develop experimental code into scalable, production-ready modules.

Platform Engineering & Infrastructure

Pipeline Orchestration: Build and maintain complex ML workflows using Kubeflow Pipelines (KFP) or similar orchestration tools.
Internal Tooling: Develop and manage the internal Python ecosystem—libraries, SDKs, and utilities—that the Data Science team uses for daily development.
CI/CD & Automation: Write and maintain CI/CD scripts to automate the testing, versioning, and deployment of machine learning artifacts.

Production Standards & Integration

System Integration: Work with backend developers to integrate trained models/agents into the core application architecture.
Code Quality: Enforce high engineering standards through code reviews, ensuring that research code meets production reliability and maintainability requirements.
Requirements Engineering: Translate evolving data science requirements into concrete infrastructure and platform features.
What we're looking for:
Experience: 10+ years in software engineering with 5+ years in backend/platform roles.
Languages: Expert-level Python; proficiency in another language, such as C++, Rust, Java, or Go, is an advantage.
Cloud & Infra: 4+ years with GCP (preferred) or AWS, including Docker, Kubernetes, and pipelines (KFP/Vertex).
ML Core: Production experience with PyTorch, Transformers, and low-level libraries (CUDA).
LLM Stack: Experience with inference optimization (e.g: vLLM/NGC) and fine-tuning (Axolotl/Huggingface).
Key Traits: Strong focus on code optimization, system reliability, and collaborative problem-solving.
Benefits & Perks:
20 paid vacation days, 18 days sick leave.
Hybrid work schedule with team meals and stocked fridges
Commuter Benefits
Community focused events
Pension Plan
Stipend per day for food
Stock options for every full-time employee
Vocational Studies Fund
