Senior Machine Learning Engineer

Our client is revolutionizing healthcare by streamlining knowledge workflows with AI. They reduce administrative burdens and elevate outcomes, empowering professionals to focus on what truly matters - improving lives. They’re growing fast and looking for bold, driven teammates to join them.

Our client is seeking a hands‑on ML/LLM Engineer who’s excited to ship real‑world applications - not just benchmarks. You’ll help build and optimize AI‑native systems that blend structured and unstructured data to power decisions in high‑stakes domains. This is a mid‑to‑senior level role for someone ready to go deep on applied ML problems - from retrieval to routing to generation - and ship solutions that deliver measurable impact.

• Own and optimize pipelines that combine classical machine learning and LLM‑based systems (RAG, scoring, summarization, etc.).
• Fine‑tune and evaluate LLMs using both open‑source and proprietary data.
• Collaborate with product and engineering teams to build real‑world applications in healthcare and biopharma.
• Implement retrieval strategies, prompt chaining, and inference orchestration for production use cases.
• Monitor and improve model quality, latency, explainability, and safety.
• Stay ahead of the curve in LLM evaluation, tuning, and agent‑based architecture.

• 3–6 years of experience in applied machine learning, with at least 1–2 years working with large language models.

• Strong Python skills and familiarity with ML/LLM frameworks such as PyTorch, Transformers, Lang Chain, Llama Index, etc.
• Experience with embeddings, vector search, retrieval pipelines, and prompt tuning for large language models.
• Bias for experimentation, clarity, and rapid deployment of solutions into production.
• Understanding of responsible AI practices, model evaluation, and observability.
• Experience with healthcare data or other compliance‑sensitive, regulated environments.

• Opportunity to make a real impact on the future of healthcare.
• Autonomy, ownership, and growth potential.
• Competitive compensation package and benefits.
• 100% employer‑paid health, vision, and dental insurance.
• Retirement plans (401(k)), disability insurance, and employee assistance programs.
