• Degree in mechanical engineering, aerospace engineering, naval architecture, marine engineering, or a related field
• 5+ years designing components and subsystems for fluid systems across a range of applications
• 5+ years of 3D CAD modeling experience
• Experience with complex, safety-critical, or high-performance fluid systems
• Strong engineering fundamentals, including hand calculations and simulation tools
• Strong written and verbal communication skills
• Ability to collaborate effectively with engineers, technicians, and external partners
• Experience contributing to multiple design-build-test cycles for complex systems

Desired Qualifications

• Advanced degree in a relevant engineering field or equivalent additional experience
• Proficiency with NX/Teamcenter or similar CAD/PLM tools
• Familiarity with marine or offshore systems (e.g., hydraulics, welded structures, mechanical assemblies)
• Experience with programming tools such as Python, Julia, or Mathematica
• Knowledge of engineering standards such as ASME Y14.5
• Strong organizational and problem-solving skills
• Ability to operate effectively in a fast-paced, iterative environment

Additional Requirements

• Travel to vendors and test sites as needed.
• Intermittently able to work longer hours and weekends to support critical needs.
