• Minimum five (5) years supporting Department of the Navy logistics commands in replenishment-at-sea operations.
• Experience supporting operational analysis, scheduling improvement recommendations, and participation in wargames, exercises, or operations.
• Minimum five (5) years developing or supporting Python web-server environments.
• Demonstrated experience translating logistics, optimization, and user-interface requirements into executable, professionally tested software solutions.

Citizenship / Clearance

• U.S. citizenship is required.

Desired Qualifications

• Experience with GAMS, Python/Pyomo optimization models, and advanced optimization tools such as NVIDIA cuOpt.
• Advanced proficiency with Microsoft Office, Excel, Visual Basic for Applications (VBA), and Office 365 interface development.
• Experience developing web-based user interfaces and deploying software in hosted server environments.
• Knowledge of mathematical optimization, multi-tier logistics modeling, and consolidation event planning.
• Strong software documentation, code repository management, testing, benchmarking, troubleshooting, and operational scenario-development skills.
• Experience supporting Navy logistics, operational research, maritime planning, or replenishment-at-sea mission areas.

Knowledge, Skills, and Abilities

• Strong understanding of mathematical optimization, logistics modeling, and operational decision-support tools.
• Proficiency developing Python-based software solutions in structured, professional software environments.
• Ability to work with Pyomo, GAMS, and related optimization frameworks.
• Strong understanding of Python web-server environments and hosted application deployment.
• Ability to develop intuitive user interfaces for technical and operational users.
• Advanced Excel, VBA, and Office 365 development skills.
• Strong technical documentation, software testing, benchmarking, and troubleshooting abilities.
• Ability to collaborate with government stakeholders, faculty, researchers, students, and technical teams.
• Strong analytical mindset with the ability to translate Navy logistics requirements into practical software capabilities.
• Ability to work independently while supporting complex software modernization objectives.

Work Environment

• Work may be performed at the Naval Postgraduate School in Monterey, CA or remotely from contractor facilities, as appropriate.
• Supports government-owned software modernization efforts and Navy logistics decision-support tools.
• Requires close coordination with NPS faculty, student researchers, Navy stakeholders, and technical development teams.
• Must comply with CUI, OPSEC, and applicable government intellectual-property requirements.
