Senior Mechanical Engineer

The Maritime Systems Division (MSD) at Leidos currently has an opening for a Senior Mechanical Engineer to work in our Lynnwood, WA office.  This is an exciting opportunity to use your experience helping us serve our Navy customers in the design, build, and test of systems related to Unmanned Underwater Vehicles (UUVs).Primary Responsibilities Lead the design and analysis of mechanical systems related to Unmanned Underwater Vehicles (UUVs), including vehicle elements (propulsion, dynamic control, structure, electronics), mission payloads, and launch & recovery systems.

Work closely with junior mechanical engineers to provide mentorship and leadership.

Create 3D models of mechanical systems using Solidworks software to describe conceptual designs and fully detail critical designs.  Create mechanical drawings per ASME Y14.100.  Maintain models and drawings in Solidworks Product Data Management (PDM) Pro tool.

Perform structural, vibration, shock, thermal, and hydrodynamic analysis of conceptual and detailed designs using hand calculations and analysis software such as Solidworks, ANSYS and COMSOL.Present mechanical designs and justify engineering decisions during engineering reviews both internally within the company and with external customers. Collaborate with colleagues across other engineering disciplines (electrical engineers, software developers, and systems engineers) to help ensure complex systems meet customer requirements.

Work with manufacturing and test & evaluation teams to build prototype systems and conduct testing in the lab and out ic Qualifications Requires B.S. degree in mechanical engineering or closely related field and 8 – 12 years of prior relevant experience or M.S. degree in mechanical engineering or closely related field and 6 – 10 years of prior relevant experience.
