About the Role

A growing AI and Data Science team at a healthcare-focused company is looking for a Senior Machine Learning Engineer to take ownership of complex, enterprise-scale ML initiatives. This is a W2 contract role for work-authorized candidates (no visa sponsorship available). You'll work in a fast-paced environment building production-grade ML solutions that directly impact patient outcomes and healthcare operations — with a strong emphasis on compliance, reliability, and end-to-end ownership.

Ideal candidates bring 8+ years of professional ML engineering experience and a mandatory background in the healthcare industry, including hands-on experience with HIPAA-compliant systems and sensitive patient data.

What You'll Do

  • Own the full ML lifecycle: data ingestion, feature engineering, model training, evaluation, deployment, monitoring, retraining, and maintenance.

  • Design and build scalable, production-ready ML systems with high availability, performance, and reliability.

  • Develop and maintain MLOps pipelines — including CI/CD, model registry, feature stores, automated deployment, monitoring, and rollback strategies.

  • Monitor production models for drift (model, data, accuracy degradation) and overall system health.

  • Build and integrate REST APIs to connect ML services into enterprise cloud applications.

  • Optimize models for latency, scalability, reliability, and operational cost.

  • Provide technical leadership on AI/ML initiatives across the organization.

  • Collaborate with Data Engineers, Software Engineers, Product Managers, Clinical teams, and business stakeholders.

  • Ensure strict compliance with HIPAA, PHI, PII, and enterprise security standards throughout all ML workflows.

What We're Looking For

Required — Dealbreakers:

  • 8+ years of professional software engineering and machine learning experience.

  • Healthcare domain experience is mandatory — including HIPAA compliance and handling of sensitive patient data (PHI/PII).

  • Demonstrated ownership of end-to-end ML lifecycle from data preparation through deployment, monitoring, and retraining.

  • Experience designing and operating production-grade ML systems at scale.

  • Hands-on MLOps: CI/CD pipelines, model registry, feature stores, automated deployment, monitoring, and rollback.

Required Technical Skills:

  • Languages: Python, SQL

  • Platforms: Databricks (production), Apache Spark (distributed computing), MLflow, Feature Store, Model Registry

  • Cloud: Azure, AWS, and/or GCP for ML workloads

  • Infrastructure: Docker, Kubernetes, REST APIs, Git, CI/CD pipelines

  • Strong debugging and performance-tuning skills; excellent stakeholder communication.

Nice to Have:

  • LLMs in production, prompt engineering, RAG, and/or GenAI applications

  • Scala

  • Azure ML, SageMaker, or Vertex AI

  • Distributed ML architecture design

  • HIPAA-compliant AI solution design experience

Compensation & Details

  • Rate: $70–75/hr on W2 (equivalent to ~$145,600–$156,000 annualized)

  • Type: W2 Contract

  • Visa sponsorship: Not available — open to all work-authorized candidates

Location

Primary location: San Francisco, CA. Additional locations considered include Los Angeles, CA and New York City, NY. Remote-friendly role.
