We are seeking a Fluid Systems Engineer to lead the design, analysis, and deployment of fluid systems for our uranium enrichment facility.

Perform system-level sizing and performance analysis for fluid systems to establish requirements and operating margins.
Translate requirements into hardware concepts, evaluating architectures and design trades for performance, safety, and manufacturability.
Design pressurized and unpressurized components and assemblies, producing original CAD models, drawings, and specifications.
Conduct structural and mechanical analysis to ensure survivability under pressure, thermal, and operational loads.
Drive design-for-manufacturability improvements to enable efficient, repeatable production.
Lead first-article builds and work directly with manufacturing teams to establish robust production processes.
Plan and execute development, qualification, and acceptance testing for critical hardware.
Define concepts of operations for systems, from commissioning and acceptance testing through steady-state operation.
Participate in internal and external design reviews with cross-functional partners, suppliers, and stakeholders.

Bachelor’s degree (or higher) in Mechanical Engineering, Aerospace Engineering, Chemical Engineering, Engineering Physics, or a related field.
+2 years of experience designing, analyzing, or testing fluid systems (e.g., pressurized systems, piping/tubing, valves, pumps, or related hardware)
Experience with gas dynamics, thermal analysis, and finite element analysis (FEA).
Hands-on experience but not limited to pressurized systems (e.g., valves, regulators, piping, tubing, pressure vessels).
Experience owning operation-critical hardware from concept through production.
Proficiency with FEA tools and CAD software
Comfortable working across disciplines with manufacturing, safety, and operations teams.
Strong communication, organization, and technical leadership skills.
Ability to work extended hours and weekends as necessary.
