Key Responsibilities

• Engineering Analysis and Design
• Perform engineering analyses and calculations supporting shipboard mechanical and machinery systems.
• Assist with the development and evaluation of preliminary designs, system concepts, and engineering alternatives.
• Analyze mechanical and fluid systems and assist in identifying system requirements, interfaces, constraints, and performance characteristics.
• Support development of equipment and system-level technical documentation.
• Review engineering drawings, diagrams, specifications, technical reports, and vendor documentation for technical accuracy and consistency.
• Assist in evaluating existing shipboard systems to identify key components, functions, interfaces, operating characteristics, and system dynamics.
• Apply engineering fundamentals to investigate technical issues and develop practical engineering recommendations.
• Support reliability engineering activities and engineering assessments as directed by the Lead Engineer.

Fluid Systems and Modeling

• Support development and analysis of shipboard fluid and machinery systems.
• Develop or review fluid-system models and engineering calculations used to evaluate system performance.
• Assist with modeling of pumps, valves, piping systems, heat exchangers, tanks, controls, and other mechanical system components.
• Support the development of system models for engineering studies and concept evaluations.
• Use engineering software and computational tools to perform calculations, evaluate alternatives, and communicate technical results.
• Develop proficiency with fluid-system modeling tools such as PIPE-FLO or comparable software as required by project assignments.
• Assist with the documentation and validation of engineering models and assumptions.

Systems Engineering and Digital Engineering

• Support the Lead Engineer in documenting system requirements, functional relationships, interfaces, and system architecture.
• Assist in developing system models and model components for complex HM&E systems.
• Research and organize technical information required to represent existing shipboard systems within modeling and simulation environments.
• Support use of digital engineering and systems modeling tools, potentially including Cameo Systems Modeler, PhoenixModelCenter, BOXARR, Innoslate, or comparable platforms.
• Assist in maintaining engineering data, assumptions, calculations, model documentation, and configuration-controlled technical products.

Technical Documentation

• Prepare engineering memoranda, technical reports, calculations, presentations, diagrams, spreadsheets, and other technical products.
• Support preparation and review of system development plans, specifications, requirements documents, and engineering studies.
• Translate technical information from government, industry, and vendor sources into clear engineering documentation.
• Research technical standards, specifications, regulations, and other engineering references applicable to shipboard systems.
• Assist in documenting engineering processes, methodologies, assumptions, and analytical results.
• Prepare meeting materials and technical briefings under the direction of the Lead Engineer.

Testing, Demonstrations, and Technical Investigations

• Provide engineering support during machinery research, development, testing, and evaluation activities.
• Participate in technical meetings, equipment demonstrations, testing activities, and site visits.
• Assist with development of test plans, data collection approaches, engineering assessments, and test documentation.
• Review test data and assist in identifying trends, anomalies, and potential engineering issues.
• Support technical investigations conducted at Philadelphia-area government, shipyard, laboratory, and vendor facilities.

Program and Team Support

• Participate in multidisciplinary engineering meetings and technical reviews.
• Track assigned technical action items and assist with preparation of meeting minutes and status updates.
• Develop task-level schedules, work plans, and technical approaches for assigned engineering activities.
• Communicate technical findings and project status clearly to the Lead Engineer and other team members.
• Coordinate with other engineers to identify technical interfaces, dependencies, and potential conflicts.
• Support preparation of engineering and acquisition documentation associated with DoD programs.
• Perform other engineering duties as assigned by the Lead Engineer or Project Manager.

Required Qualifications

• Bachelor's degree in Mechanical Engineering, Marine Engineering, Naval Architecture, or a closely related engineering discipline.
• 3-5 years of relevant engineering experience. Strong candidates with less than two years of experience will be considered.
• Demonstrated understanding of fundamental mechanical engineering principles, including fluid mechanics, thermodynamics, heat transfer, mechanics, and/or machine design.
