About this Mechanical Engineer role at Leidos
The Leidos Undersea Systems Division (USD) team currently has an opening for a Mechanical Engineer supporting NIWC Pacific. This is an exciting opportunity to use your experience helping the NIWC Pacific mission in the design, development, and deployment of payloads, UUV systems, and other technologies. The candidate will collaborate with an interdisciplinary team of technicians, engineers, and scientists to research detection technologies, interface with users to understand needs and requirements, and field complete solutions. This position will require the candidate to obtain and hold a Secret Clearance.
- Primary Responsibilities:
- The Mechanical Engineer will work with a small team of engineers and technicians in development, test, and delivery of mechanical systems based on system requirements. Development includes design, implementation, and integration of mechanical hardware or sensors onto systems for deployment at-sea. Most development and testing will be conducted in San Diego; however, engineers may occasionally be asked to travel in support of testing and/or operations in other locations both in the U.S. and abroad. The Mechanical Engineer will perform tasks such as mechanical engineering design using Computer Aided Design (CAD), mechanical drawings, analysis on underwater systems, provide test and evaluation, engineering, and prototype fabrication for various at-sea and pier-side systems and component tests.
- Basic Qualifications:
- The minimum requirements for this position include:
Bachelor’s degree in mechanical engineering or related field with 6 years of applicable experience.
Ability to obtain and maintain a Secret Clearance.
Must have experience with mechanical engineering design and analysis, as well as test and evaluation of mechanical systems.
Must be proficient in CAD design, preferably with Solid edge, alternate in SolidWorks.
Must be able to work effectively in a team environment and have excellent communication skills.
- The minimum requirements for this position include:
- Preferred Qualifications:
- Knowledge of underwater systems, UUVs, or other related technologies with deep-rated systems (3,000-11,000m)
- Experience in design work with Subsea Mechanical, CCA chassis mounting, CCA and system thermal analysis.
- Experience with test and evaluation of at-sea systems.
- Involvement with rapid prototyping for test and system hardware.
- FEA expertise: ANSYS, SolidWorks Simulation, Abaqus, or Nastran for structural and thermal analysis.
- CFD expertise: ANSYS, SolidWorks Flow Simulation or similar.
- Python/Matlab for automation, data analysis, or design optimization.
- Experience working in a fast-paced, research, development, testing, and evaluation environment.
- Previous experience working with government agencies, particularly NIWC Pacific, is a plus.
- Electro-Mechanical sub-sea system testing:
- Assembly and refurb of subsystem in the test event.
- Assist/lead benchtop testing with electronics and software engineers.
- At sea testing of systems.
- Curating test objectives and test milestones at the subsystem level to meet major system milestones.
- Physical ability to:
- Navigate lab, office, and warehouse environments—including frequent movement around piers, docks, and facility spaces—with the ability to stoop, kneel, reach for extended periods, and transport objects weighing up to 50 lbs. across the facility.
- Use hands to operate machinery, tools, and computer equipment.
- Climb ladders up to 20 ft and work comfortably in loud production environments, various temperatures, and inclement weather. This includes a willingness to work aboard marine vessels of various sizes, occasionally on an overnight basis.
- Willingness to travel occasionally in support of testing activities.
