About The Position

The Leidos Undersea Systems Division (USD) team currently has an opening for a Mechanical Engineer supporting NIWC Pacific. Candidate will support cutting-edge maritime technologies and work across a multitude of product lines. Responsibilities will be split dynamically between Configuration Management (CM) and managing the development and execution of Temporary Alteration Packages (TEMPALT) for temporary installation of equipment/systems on Navy platforms. As a key member of a large, collaborative engineering team, candidate will act as a primary technical bridge ensuring that our advanced maritime hardware configurations are flawlessly documented and successfully integrated into naval vessels. This position offers a unique balance of detailed engineering, configuration control, shipboard technical documentation, and hands-on system integration support. This position will require the candidate to maintain a Secret Clearance. This position will require the candidate to work an onsite 9/80B schedule (80 hours of work into nine days over a two-week period, allowing for every other Friday off) to align with the NIWC government team.

Requirements

Bachelor of Science (BS) in Mechanical Engineering, Marine Engineering, Naval Architecture, or a closely related technical field.
2-5+ years of professional experience in mechanical design, structural integration, or configuration control, preferably within maritime, aerospace, or defense sectors.
Strong proficiency in 3D CAD design software (Solid Edge preferred)
Solid understanding of Configuration Management principles (ANSI/EIA-649 standard) and configuration control workflows.
Basic structural and mechanical calculation skills (e.g., stress analysis, center of gravity, load-bearing capacities, bolt torque).
Excellent verbal and written communication skills to interface effectively with shipyard personnel, design engineers, and Navy officials.
U.S. Citizenship is required.
Ability to obtain and maintain a Department of Defense (DoD) Secret Security Clearance. (Top Secret preferred)
Willingness to travel as needed. (Anticipate 2-8 trips per year, with trips ranging from 3-days to 2- weeks in duration.)

Nice To Haves

Direct Navy Experience: Prior experience working directly on US Navy surface vessels or submarines.
Familiarity with US Navy standard procedures, NAVSEA drawing requirements, and TEMPALTs / ShipAlts / Combat System Alts.
Knowledge of Navy shock and vibration standards (MIL-S-901D, MIL-STD- 167-1A) and electromagnetic interference controls (MIL-STD-461).
Certification in Configuration Management (e.g., NDIA CM, CMPIC, or similar).
Hands-on shipboard mechanical assembly
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 75 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.

Responsibilities

Establish and maintain system baseline configurations, drawing trees, and documentation packages across multiple systems.
Perform detailed reviews of engineering drawings, 3D CAD models (Solid Edge), and technical specifications to verify standards compliance, accuracy, and completeness.
Manage Engineering Change Orders (ECOs) and deviations, leading them through review boards and ensuring exact lifecycle documentation.
Track hardware revisions and ensure physical systems match the digitized as-designed models across multiple product lines.
Collaborate across systems, electrical, and software engineering disciplines to ensure seamless configuration traceability.
Support the generation and technical orchestration of Temporary Alteration (TEMPALT) packages in accordance with NAVSEA and US Navy requirements (e.g., NAVSEAINST 4790.8).
Perform reviews of shipboard installation packages, including review of designs for structural foundations, shock/vibration isolation mountings, cabling pathways, and power distribution interfaces.
Develop technical installation instructions, shipboard safety briefs, drawing packages, and testing/restoration procedures.
Conduct ship checks and site surveys on naval vessels to assess structural fitment, clearance limits, and interference resolution.
Provide on-site technical support to shipyards, installation teams, and ship crew during TEMPALT execution and initial system commissioning.
Coordinate closely with Navy program offices, regional maintenance centers (RMCs), and ship command staff to gain package approvals and manage technical risks.
