Senior Engineer, Machine Learning

The role

You will build and deploy production-grade machine learning models on Virta's ML platform. You will turn clinical and operational questions into ML tasks to drive member care and personalized coaching.

What you will do

• Turn ambiguous clinical and operational questions into well-scoped ML tasks.
• Build predictive models that drive member care.
• Build per-model logic for retraining, drift, and anomaly detection.
• Design offline and online evaluations and run error analysis.
• Build causal models validated against real clinical experiments.
• Build ML-and GenAI-derived signals for product squads.
• Lead complex ML initiatives from problem framing through production.
• Share knowledge and practices to strengthen model quality.

Required qualifications

• 5+ years building, evaluating, and deploying production-grade Machine Learning systems for real-world use cases.
• Strong foundation in traditional ML (predictive modeling, tree-based models like XGBoost, time-series analysis on structured longitudinal data).
• Rigorous evaluation and experimental design: statistical reasoning, offline/online evaluation, and a habit of identifying leakage, selection bias, and confounding in messy real-world data.
• Ability to explain model behavior, tradeoffs, uncertainty, and limitations clearly to both technical and non-technical stakeholders.
• Experience designing and analyzing experiments to determine what actually drives an outcome, not just what correlates with it.
• Depth in one or more of: causal ML and experimentation, recommendation/ranking systems, predictive modeling, or NLP/LLM-based systems.
• Responsible use of AI-assisted development to meaningfully accelerate and improve model development.

Nice to have

• Background in clinical or health-tech ML (claims, EHR, clinical notes, scheduling, utilization, or member engagement data), and experience with PHI, HIPAA-aware systems, or other regulated data.
• Judgment about when traditional ML outperforms LLMs, and when an LLM is the right tool.

Before you apply

• Corporate roles: We currently do not hire in the following states: AK, DE, HI, ME, MS, OK, SD, VT.
• Virta uses Ashby as its applicant tracking system, which incorporates AI-powered tools in certain aspects of the recruiting process, including application review, candidate screening, and interview no
