About the role

  • We are seeking a Senior Data Scientist Engineer to lead the design, development, and deployment of advanced AI/ML solutions supporting complex mission and operational environments.
  • This role is ideal for an experienced engineer who can operate independently in ambiguous technical settings, guide high-impact model development, and help translate raw data into actionable intelligence through scalable, production-ready machine learning solutions.
  • The ideal candidate brings deep experience in applied machine learning, strong technical judgment, and the ability to collaborate across engineering and analyst teams while mentoring other engineers and improving the reliability, explainability, and operational readiness of deployed models.

Responsibilities

  • Lead development, training, optimization, and deployment of advanced AI/ML models in support of mission and operational objectives.
  • Define and implement technical approaches for model development, validation, explainability, monitoring, and lifecycle management.
  • Build and improve automated data ingestion, curation, retraining, and model delivery pipelines to support long-term adaptability and performance.
  • Monitor model performance, implement drift detection and testing approaches, and improve reliability through continuous evaluation and optimization.
  • Collaborate with analysts, mission experts, software engineers, and other stakeholders to validate model outputs and align solutions to operational needs.

Requirements

  • Bachelor's degree or higher in a quantitative discipline such as statistics, mathematics, operations research, engineering, computer science, or a related technical field.
  • Active TS/SCI clearance with CI Polygraph required at time of application.
  • Experience leading complex AI/ML efforts and operating independently in technically ambiguous, high-consequence environments.
  • Strong experience with supervised, unsupervised, and ensemble modeling approaches, including neural network-based methods.
  • Experience with model validation, performance monitoring, explainability, and reproducibility practices.
  • Experience collaborating across engineering, analyst, and operational stakeholders to align models to mission needs.

Nice to have

  • Proficiency with frameworks and libraries such as TensorFlow, PyTorch, Scikit-learn, XGBoost, or similar tools.
  • Familiarity with distributed data or compute frameworks including Spark, Ray, or Dask.
  • Working knowledge of ML lifecycle and deployment tooling such as MLflow, DVC, Docker, or similar environments.
  • Comfort working in Agile or DevSecOps environments using tools such as Git, Jupyter Notebooks, Confluence, or similar collaboration platforms.
  • Demonstrated success mentoring engineers or guiding technical work in applied AI/ML environments.
  • Prior work in the DoD or Intelligence Community supporting mission-critical data science applications.
  • Exposure to enterprise AI initiatives, production ML governance, or high-consequence analytical systems.
  • Guide technical decision-making related to model performance, interpretability, reproducibility, and deployment tradeoffs.

Compensation

  • The salary range for this role is $193,700.00 - $262,000.00 per year.
  • The salary range provided is a good faith estimate representative of all experience levels.
