Senior Systems Engineer - Thermal

Key Responsibilities

• Support the Thermal IPT Lead in defining and maintaining thermal subsystem requirements, including allocation, traceability, and verification planning
• Develop and maintain interface definitions (ICDs) between thermal hardware and spacecraft subsystems (structures, avionics, propulsion, EPS)
• Cook up and validate ICDs, ensuring design closure and requirements compliance
• Contribute to verification & validation (V&V) planning, including definition of test methods, success criteria, and requirement mapping
• Develop and execute thermal test plans (component, subsystem, and vehicle-level), including thermal balance and TVAC campaigns
• Support integration and test (I&T) activities, including instrumentation planning, test setup definition, and data review
• Generate and maintain engineering documentation (ICDs, test plans, procedures, verification matrices)
• Support procurement and build of thermal hardware, including vendor coordination and drawing reviews
• Participate in internal and customer design reviews (SRR/PDR/CDR) and present status, risks, and technical findings
• Identify and communicate risks, gaps, and integration issues, proactively driving resolution in a fast-paced development environment

Required Qualifications

• 5–10 years of relevant spacecraft or aerospace systems experience
• Bachelor’s degree or higher in Mechanical, Aerospace, or related field
• Demonstrated experience with requirements development, flowdown, traceability and verification (Jama or similar tools preferred)
• Experience defining and managing interfaces (ICDs) across multidisciplinary systems
• Direct experience supporting or executing thermal test campaigns
• Working knowledge of passive and active thermal control hardware: MLI, heaters, radiators, coatings, heat pipes, fluid loops
• Strong understanding of space thermal environments and heat transfer in space environments (radiation-dominated systems)
• Excellent organization and time management skills
• U.S. Person

Preferred Qualifications

• Familiarity with Thermal Desktop, SINDA/FLUINT, or equivalent tools
• Startup or rapid development program experience
• Experience with NASA/DoD standards (GEVS, MIL-STD,SMC and EHP)
• Experience with verification method selection and standards tailoring based on risk posture
• Thermal instrumentation and test data analysis experience
• Experience supporting configuration management and change control processes
