Job description

Senior Machine Learning Engineer

We’re a leading health technology company on a mission to help people get better. We started in 2011 with one simple idea : make it easier for practitioners to access the products they trust so they can deliver better care. That simple idea grew into a platform that powers every part of care. More than 125,000 practitioners use Fullscript for clinical insights, lab interpretations, patient analytics, education, and access to high‑quality supplements. Over 10 million patients rely on Fullscript to stay connected to their care plans and follow through on treatment. We build tools that make care smarter, more human, save time, simplify decisions, and help practitioners stay closely connected to the people they care for.

We’re hiring a Senior Machine Learning Engineer to join our AI team to help strengthen and expand Fullscript’s AI‑powered experiences. You’ll work on building innovative AI capabilities that help clinicians provide better services and help patients improve their health.

What you’ll do

  • Development and deployment of LLM‑powered features, including summarization tools and clinician‑facing conversational agents
  • Build backend services in Python that integrate ML / LLM models with Fullscript’s platform
  • Implement prompt engineering techniques to optimise model outputs
  • Implement AI feature quality testing, CI / CD pipelines, and version control for all model‑related workflows
  • Collaborate with medical and product teams to deliver AI features for practitioners and patients
  • Work cross‑functionally with engineering, analytics, and medical SMEs to refine requirements and ensure data solutions support clinical contexts
  • Stay current with the latest LLM research and emerging AI technologies

What you bring to the table

  • 3+ years of experience building and implementing LLM applications
  • Experience with LLM application frameworks (LangChain, LangGraph, Hugging Face tools)
  • Familiarity with model evaluation and monitoring frameworks
  • Knowledge of MCP and agent orchestration tools
  • Strong proficiency in Python and SQL
  • Deep understanding of data engineering best practices, including version control, testing, and CI / CD methodologies
  • Ability to communicate complex technical concepts effectively to technical and non‑technical stakeholders
  • Learning mindset, with a keen interest in exploring new technologies and methodologies
  • Bonus if you have

  • Familiarity with model evaluation and monitoring frameworks
  • Snowflake Snowpark or PySpark experience
  • Knowledge of MCP, Langfuse, or other agent orchestration tools
  • Graph database experience (Neo4j)
  • Exposure to healthcare, clinical data, or decision‑support systems
  • What we can offer you

  • Flexible PTO & competitive pay—rest fuels performance
  • RRSP match & stock options—invest in your future
  • Customizable benefits—flexible coverage, paramedical services, and an HSA
  • Fullscript discounts—save on wellness products
  • Continuous learning—training budget + company‑wide initiatives
  • Hybrid and remote flexibility—Wherever You Work Well
