• Evaluate and integrate emerging AI and LLM technologies where they can improve provider efficiency, patient outcomes, or operational scale

• Lead complex technical initiatives that span multiple teams and systems

• Mentor engineers and provide technical leadership through design reviews, architecture discussions, and hands-on implementation

• Influence the long-term technical direction of the MedMatch platform and broader AI ecosystem

You Have:

• 8+ years of professional software engineering experience building and operating production systems at scale

• Familiarity with ML lifecycle concepts including training, evaluation, deployment, monitoring, and experimentation

• Experience with cloud platforms and modern infrastructure tooling (AWS, Kubernetes, Databricks, MLflow, Airflow, etc.) is a plus

• Ability to balance short-term product delivery with long-term platform scalability and maintainability

• Excellent collaboration and communication skills, with the ability to work effectively across engineering, product, data science, and clinical stakeholders

Nice to Have:

• Experience building recommendation systems, ranking systems, personalization platforms, or decision-support systems

• Experience in healthcare, health tech, or other regulated environments

• Advanced degree in Computer Science, Machine Learning, or a related field
