Mechanical Engineer Security Clearance

Position: Mechanical Engineer with Security Clearance
We are seeking a skilled and driven Mechanical Engineer to join our engineering team based in Edmonds, WA. This is a design-focused role that spans the full product lifecycle - from early concept development through hardware fabrication, installation, and on-site operation. The ideal candidate is a licensed or degree-qualified mechanical or aerospace engineer who brings deep expertise in mechanical systems design, structural analysis, and high-pressure fluid systems, and who communicates and collaborates effectively across engineering and operations teams.

This position offers the opportunity to lead and participate in design reviews, work alongside vendors to bring hardware from drawing to reality and provide direct technical support during field installation and testing. If you are looking for a role where your engineering decisions have real, visible consequences on mission-critical systems, this is the opportunity for you. This team supports multiple US Navy research and development facilities associated with top priority submarine weapon system development programs.

The facilities are one-of-a-kind and provide a capability not found anywhere else in the DoD. This role is perfect for someone who thrives in a dynamic and fast-paced environment and is willing to tackle problems that span the hardware lifecycle.

Job Duties and Responsibilities:

Mechanical Design & Analysis
• Lead mechanical design efforts from concept development through detailed design, fabrication support, and on-site commissioning.
• Develop and review engineering drawings, models, and specifications using CAD and solid modeling software (Solid Works, AutoCAD, Inventor, or equivalent).
• Perform structural analysis to validate designs meet strength, fatigue, and safety requirements under operational loading conditions.
• Evaluate designs for manufacturability, maintainability, and compliance with applicable codes and standards.
• Drive projects through the full lifecycle - from initial concept and requirements definition through fabrication, installation, testing, and operational turnover. High-Pressure & Fluid Systems

• Apply engineering expertise in high-pressure air and hydraulic systems, including component selection, system layout, pressure calculations, and safety system design.

• Review and develop P&IDs, hydraulic schematics, and fluid system drawings to support design and fabrication activities.

• Conduct and support pressure system design reviews in accordance with applicable standards (ASME, ANSI, or program-specific requirements).

• Troubleshoot high-pressure and hydraulic system anomalies in both design and field environments, identifying root cause and driving corrective actions. Design Review & Work Package Support

• Lead and actively participate in formal design reviews (PDR, CDR, and peer reviews), ensuring technical rigor, safety compliance, and design completeness.

• Review work packages, installation procedures, and test plans to confirm accuracy, completeness, and alignment with engineering intent prior to field execution.

• Evaluate proposed design changes and engineering change orders for technical feasibility, safety impact, and compliance.

• Collaborate with senior engineers and cross-functional teams to translate requirements into robust, producible designs. Vendor Coordination & Fabrication Support

• Work directly with vendors and fabricators to communicate design intent, clarify technical requirements, and ensure hardware is manufactured to specification.

• Review vendor submittals, fabrication drawings, and material certifications to verify conformance with design requirements.

• Support procurement activities by developing specifications, statements of work, and technical evaluation criteria for hardware and services.

• Coordinate factory acceptance testing and witness inspections as required to validate hardware quality prior to delivery. Technical Reporting & Documentation

• Write and review technical reports documenting hardware performance, design analyses, test results, and issue identification and resolution.

• Produce clear, accurate engineering documentation including design memos, field reports,…
