Original job description

Apply Job Type Full-time Description TDI is seeking a motivated Mechanical Engineer to support preliminary design activities for the Navy's future surface combatant ship. This position targets an early-career engineer with approximately 3-5 years of professional experience who is interested in developing expertise in shipboard mechanical systems, engineering analysis, systems engineering, modeling and simulation, and naval ship design. The Mechanical Engineer will contribute to the development, analysis, documentation, and integration of shipboard hull, machinery, and mechanical systems. The successful candidate will receive increasing levels of technical responsibility as experience and proficiency are demonstrated. The position provides an opportunity to work on technically challenging engineering problems involving complex shipboard systems and to collaborate with naval architects, mechanical and electrical engineers, mathematicians, systems engineers, cybersecurity personnel, government stakeholders, and industry partners. The position is based at the Naval Shipyard in Philadelphia, Pennsylvania (NSWCPD) and will require periodic travel to government, shipyard, laboratory, and vendor facilities in support of engineering meetings, testing, demonstrations, and technical investigations. Benefits: Medical, Dental, Vision, Life Insurance, Disability Insurance, Voluntary Benefits, 401K, Tuition Assistance, Paid Vacation, Paid Holiday, and Paid Sick Leave. Key Responsibilities The Mechanical Engineer will support the Lead Engineer in the following areas: 1. Engineering Analysis and Design 2. Perform engineering analyses and calculations supporting shipboard mechanical and machinery systems. 3. Assist with the development and evaluation of preliminary designs, system concepts, and engineering alternatives. 4. Analyze mechanical and fluid systems and assist in identifying system requirements, interfaces, constraints, and performance characteristics. 5. Support development of equipment and system-level technical documentation. 6. Review engineering drawings, diagrams, specifications, technical reports, and vendor documentation for technical accuracy and consistency. 7. Assist in evaluating existing shipboard systems to identify key components, functions, interfaces, operating characteristics, and system dynamics. 8. Apply engineering fundamentals to investigate technical issues and develop practical engineering recommendations. 9. Support reliability engineering activities and engineering assessments as directed by the Lead Engineer. Fluid Systems and Modeling 1. Support development and analysis of shipboard fluid and machinery systems. 2. Develop or review fluid-system models and engineering calculations used to evaluate system performance. 3. Assist with modeling of pumps, valves, piping systems, heat exchangers, tanks, controls, and other mechanical system components. 4. Support the development of system models for engineering studies and concept evaluations. 5. Use engineering software and computational tools to perform calculations, evaluate alternatives, and communicate technical results. 6. Develop proficiency with fluid-system modeling tools such as PIPE-FLO or comparable software as required by project assignments. 7. Assist with the documentation and validation of engineering models and assumptions. Systems Engineering and Digital Engineering 1. Support the Lead Engineer in documenting system requirements, functional relationships, interfaces, and system architecture. 2. Assist in developing system models and model components for complex HM&E systems. 3. Research and organize technical information required to represent existing shipboard systems within modeling and simulation environments. 4. Support use of digital engineering and systems modeling tools, potentially including Cameo Systems Modeler, PhoenixModelCenter, OXARR, Innoslate, or comparable platforms. 5. Assist in maintaining engineering data, assumptions, calculations, model documentation, and configuration-controlled technical products. Technical Documentation 1. Prepare engineering memoranda, technical reports, calculations, presentations, diagrams, spreadsheets, and other technical products. 2. Support preparation and review of system development plans, specifications, requirements documents, and engineering studies. 3. Translate technical information from government, industry, and vendor sources into clear engineering documentation. 4. Research technical standards, specifications, regulations, and other engineering references applicable to shipboard systems. 5. Assist in documenting engineering processes, methodologies, assumptions, and analytical results. 6. Prepare meeting materials and technical briefings under the direction of the Lead Engineer. Testing, Demonstrations, and Technical Investigations 1. Provide engineering support during machinery research, development, testing, and evaluation activities. 2. Participate in technical meetings, equipment demonstrations, testing activities, and site visits. 3. Assist with development of test plans, data collection approaches, engineering assessments, and test documentation. 4. Review test data and assist in identifying trends, anomalies, and potential engineering issues. 5. Support technical investigations conducted at Philadelphia-area government, shipyard, laboratory, and vendor facilities. Program and Team Support 1. Participate in multidisciplinary engineering meetings and technical reviews. 2. Track assigned technical action items and assist with preparation of meeting minutes and status updates. 3. Develop task-level schedules, work plans, and technical approaches for assigned engineering activities. 4. Communicate technical findings and project status clearly to the Lead Engineer and other team members. 5. Coordinate with other engineers to identify technical interfaces, dependencies, and potential conflicts. 6. Support preparation of engineering and acquisition documentation associated with DoD programs. 7. 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 re
