Mechanical Engineer, Fluids, Environmental, and/or Thermal Control

Job description

Job responsibilities

• Select and qualify fluid and thermal system components (valves, sensors, regulators, pumps, heat exchangers, fittings).
• Conduct trade studies, define requirements, and work with suppliers to ensure components meet performance and environmental needs.
• Develop and execute test plans for component-level verification, including pressure and flow testing, thermal cycling, and leak testing.
• Analyze test data, troubleshoot anomalies, and document results in formal reports.
• Perform integrated system analyses combining fluid dynamics, thermodynamics, and heat transfer to size components and predict system behavior.
• Build and correlate analytical models (MATLAB/Python, CFD, or thermal tools) using component and system test data.
• Generate and maintain system documentation including P&IDs, interface control documents, drawings, and specifications.
• Collaborate with cross-functional teams (Stress, avionics, manufacturing) to ensure proper integration and meet mission requirements.

Job requirements

• BS in Mechanical Engineering (or Aerospace engineering) is required.
• 5+ years of experience working on mechanical, fluid, or thermal systems.
• Experience with fluid and/or thermal system design, analysis, and testing.
• Proficiency with mechanical design tools (CAD such as NX, Creo, or SolidWorks) and analysis tools (MATLAB, Python, or equivalent).
• Experience designing or analyzing fluid components (valves, regulators, pumps, lines, manifolds) or thermal systems (heat exchangers, radiators, cold plates).
• Demonstrated ability to take engineering designs from concept through testing to production and delivery.
• Strong communication, documentation, and troubleshooting skills.
• Hands-on experience with test execution (pressure testing, flow testing, thermal cycling) and post-test data analysis.
