We are seeking a highly motivated, execution-focused Thermal Engineer to support advanced aerospace hardware development programs. This role is ideal for a junior to mid-level engineer who thrives in fast-paced environments, works independently, and consistently delivers high-quality analysis, documentation, and testing support.

You will contribute directly to thermal modeling, system-level testing, and qualification activities spanning two key programs:
Kuiper Modem Module and Optical Communications Terminal v2 (OCT v2). Candidates with strong hands-on testing experience coupled with analytical proficiency are encouraged to apply.

• Kuiper Modem Module (50% allocation / 12 months)
  • Provide thermal design inputs to mechanical, electrical, and cross-functional engineering teams.
  • Develop and execute thermal modeling using Thermal Desktop (SINDA) and/or ANSYS thermal tools (Icepak, Fluent, Mechanical).
  • Prepare comprehensive documentation including analysis reports and test plans.
  • Build thermal testing and qualification plans.
  • Conduct thermal testing, data collection, and correlation of test results to thermal models.
• Optical Communications Terminal v2 – OCT v2 (50% allocation / 12 months)
  • Execute thermal trade studies for electronic enclosure architectures.
  • Perform preliminary thermal analysis for PCB assemblies.
  • Collaborate with design teams to support early mechanical concepts.
  • Define, plan, and execute development-stage thermal testing activities.

• Bachelor’s degree in mechanical engineering or a related technical discipline (or equivalent experience).
• 3+ years of experience using Thermal Desktop (SINDA) and/or ANSYS thermal analysis tools (Icepak, Fluent, Mechanical).
• 2+ years of hands-on thermal testing experience including test planning, thermocouple/heater installation, DAQ operation, power supply operation, correlation, and verification.
• Experience writing engineering documentation, including reports, test plans, and results summaries.

• Experience with avionics thermal design and analysis
  .
• CAD proficiency (NX, Solid Works).
• Experience correlating thermal models with test data.
