  • Perform thermal analysis and modelling for components development, such as valves, actuators, and minor structural propulsive elements. 
  • Collaborate with design teams to develop thermal control strategies and solutions, including the selection of metallic and plastic materials, insulation, and thermal protection systems. 
  • Conduct thermal design reviews to ensure compliance with thermal requirements. 
  • Analyze and optimize the thermal performance of critical components, such as engines, turbopump, valves, actuators, motors piping, tubing, and seals. 
  • Perform transient and steady-state thermal simulations using specialized software tools to evaluate system performance under various operational conditions and environmental factors. 
  • Conduct thermal testing and validation of hardware and subsystems, including hot-testing, cryogenic testing, thermal vacuum tests and thermal cycling tests. 
  • Provide technical expertise and guidance on thermal issues throughout the design, development, and testing phases. 
  • Collaborate with cross-functional teams, including mechanical engineers, systems engineers, and manufacturing teams, to ensure thermal considerations are integrated into the overall system design. 
  • Generate thermal analysis reports, documenting methodologies, assumptions, and results for internal use and customer review. 
  • Generate documentation, including user guides, guidelines and user manuals for internal customers use. 
  • Generate documentation for formal program development reviews.
