Senior Data Engineer Digital Twin & Operational Modeling

Job Description

• Data Architecture & Pipelines: Design and build scalable data architectures and pipelines that power digital twin, analytics, and modeling initiatives; architect ingestion, integration, transformation, storage, and access across structured and unstructured sources; integrate operational, clinical, resource, scheduling, and logistics data on cloud-based platforms using modern data engineering practices.
• Digital Twin Development: Lead data and model development for a digital twin of the OR environment that represents physical and operational processes through data and computational models; partner with DHA and MHS stakeholders to map workflows, resources, constraints, and dependencies; translate real-world OR workflows into data models, process models, and simulation models.
• Scenario Modeling & Analytics: Build “what-if” and scenario-analysis capabilities that evaluate changes in staffing, scheduling, room utilization, equipment, patient flow, and capacity; apply statistical modeling, optimization, machine learning, or simulation techniques where appropriate; analyze large, complex datasets to identify bottlenecks, inefficiencies, and optimization opportunities.
• Data Products & Integration: Deliver dashboards, analytical models, and decision-support tools that turn complex data into actionable insights for operational planning; design APIs and data services that connect digital twin and analytical capabilities to other enterprise systems.
• Governance, Documentation & Communication: Establish data quality, governance, lineage, validation, and monitoring processes; document architectures, models, pipelines, algorithms, assumptions, and system dependencies; communicate complex technical and analytical concepts clearly to technical teams, healthcare stakeholders, and government leadership.

Qualifications

• Experience supporting DoD healthcare, or other large healthcare environments.
• Experience with digital twins, discrete-event simulation, agent-based modeling, or operations research.
• Experience modeling complex, resource-constrained environments such as hospitals, operating rooms, emergency departments, logistics networks, or supply chains.
• Familiarity with healthcare operations — OR and surgical case scheduling, patient flow, staffing and resource allocation, room and equipment utilization, supply and logistics management, and capacity planning.
• Experience developing optimization, predictive, mathematical, statistical, or machine learning models.
• Hands-on experience with simulation and modeling tools such as AnyLogic, SimPy, Arena, MATLAB/Simulink, or comparable Python-based frameworks.
• Experience with AWS services including Amazon S3, AWS Glue, AWS Lambda, Amazon Redshift, Amazon RDS, Amazon EMR, Amazon SageMaker, and AWS Lake Formation.
• Experience with modern data platforms and tools such as Databricks, Snowflake, Apache Spark, Apache Kafka, or Apache Airflow.
• Experience developing APIs and integrating data platforms with enterprise applications.
• Ability to obtain and maintain the required DoD security clearance; Public Trust (healthcare) clearance preferred. US Citizen required. 
• Bachelor's degree in Computer Science, Data Science, Engineering, Operations Research, or a related field, or equivalent practical experience.
• Experience: 7+ years of experience in data engineering, data architecture, analytics engineering, or a related discipline, including hands-on design and implementation of data pipelines and data platforms.
• Data Engineering: Proven expertise in data modeling, database architecture, ETL/ELT, data integration, and data transformation; experience with relational and/or NoSQL databases; track record designing data solutions that support analytics, modeling, simulation, or operational decision-making.
• Cloud & Programming: Experience with cloud-based data platforms, preferably AWS; strong SQL skills plus proficiency in one or more programming languages such as Python, Java, or Scala.
• Governance & Security: Working knowledge of data quality, governance, metadata management, lineage, and data security practices.
• Problem Solving & Collaboration: Strong analytical and problem-solving skills; ability to translate complex operational processes into technical, data-driven solutions; comfortable collaborating with data scientists, architects, SMEs, and government stakeholders.
