Senior Machine Learning Engineer

About the Role

This is a Senior Machine Learning Engineer role embedded within a growing AI and Data Science team at a healthcare-focused data and analytics company. You'll take end-to-end ownership of enterprise-scale ML solutions — from raw data through to production — playing a critical part in delivering compliant, high-impact AI capabilities in a regulated healthcare environment.

What You'll Do

• Design, develop, deploy, and maintain enterprise-scale machine learning solutions from the ground up.

• Build end-to-end ML pipelines covering data ingestion, feature engineering, model training, evaluation, deployment, monitoring, and retraining.

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

• Monitor production models for drift, accuracy degradation, and overall system health.

• Develop REST APIs and integrate ML services into enterprise cloud applications.

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

• Collaborate cross-functionally with Data Engineers, Software Engineers, Product Managers, and Clinical teams.

• Provide technical leadership on AI/ML initiatives and ensure compliance with HIPAA, PHI, and PII standards.

What We're Looking For

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

• Strong healthcare industry background — this is a firm requirement.

• Deep expertise across the full ML lifecycle: preprocessing, feature engineering, model development, calibration, deployment, monitoring, and maintenance.

• Hands-on MLOps experience with strong Python and SQL skills.

• Proficiency with distributed computing (Apache Spark) and Databricks in production environments.

• Experience with at least one major cloud platform (Azure, AWS, or GCP).

• Familiarity with MLflow, Feature Stores, Model Registries, Docker, and Git.

• Experience building and integrating REST APIs; strong debugging and performance-tuning skills.

• Working knowledge of HIPAA compliance requirements when handling sensitive healthcare data.

• Nice to have: LLMs in production, RAG/prompt engineering, GenAI, Kubernetes, Scala, or managed ML platforms (Azure ML, SageMaker, Vertex AI).

• US work authorization required; visa sponsorship is not available.
