As a Senior Lead Ground System Fluid/Mechanical Engineer, you will serve as both a hands-on technical contributor and a technical authority for the design, development, and delivery of complex fluid and mechanical ground test systems. You will personally own and deliver detailed design and analysis packages while simultaneously being a technical leader, driving system architecture decisions, holding program technical approval authority, and shaping the engineering direction of world-class test infrastructure. You will mentor engineers at all levels and represent the team as the prime technical contact with customers and stakeholders. Passion for our mission and vision is required! Special Mentions Relocation available Up to 25% travel required between facilities and for field operations from the Kent, Washington location Interviews will include a technical assessment.

Responsibilities

• Lead and personally execute the design and development of fluid and mechanical systems for ground test facilities across the full system lifecycle, from System Requirement Review (SRR) through Pre-Activation Review (PAR), independently and without oversight
• Own and deliver detailed design and analysis packages - including P&IDs, fluid system analyses, pipe stress analyses, structural calculations, and supporting engineering documentation - while also setting quality standards and reviewing the work of engineers at all levels
• Develop advanced technical solutions to complex, cross-disciplinary design challenges in high-pressure gas, cryogenic, and propellant fluid systems; personally execute and own system architecture decisions and trade studies
• Perform engineering reviews of P&IDs, components, and analyses across assigned programs to verify technical accuracy and completeness prior to release
• Own and chair hazard assessments including Process Hazard Analysis (PHA) and Hazard and Operability Studies (HAZOPs); define safety standards and ensure compliance across assigned programs
