  • Support testing in laboratories, shipyards, industrial, and shipboard environments.
  • Use electrical test equipment such as oscilloscopes, digital multimeters, power analyzers, insulation resistance testers, load banks, and data acquisition systems.
  • Support preventive and corrective maintenance planning, execution, and documentation.
  • Provide on-site collaboration and engagement within the Advanced Power Systems Division of NSWC PD.
  • Support and continuously meet with NSWC PD clients and the overall design team.
  • Participate in technical working groups such as the IPS Working Group (WG), Auxiliary/Deck WGs, and HME Controls WGs.
  • Effectively communicate complex marine engineering design architectures, system dependencies, trades, and design decisions.
  • Perform systems engineering, trade space management and exploration, design decisions, and configuration management of marine engineering datasets.
  • Provide cross-program support and design integration across established IPTs such as IPS, Auxiliary, Survivability, and Affordability teams.
  • Perform calculations, apply electrical and marine engineering principles, and conduct quality assurance reviews of US Navy Ship and ship system design artifacts.
  • Communicate directly with clients and stakeholders to effectively convey technical principles and design status.
  • Record action items, track meeting minutes, and manage meeting invites.
