Senior Thermal-Structural Analyst, Spacecraft Systems

Portal Space Systems; Bothell (WA); On-site; USD 120,000 - 170,000; Full time

Job summary

Portal Space Systems seeks a Senior Thermal-Structural Analysis Engineer to substantiate spacecraft structures in high-temperature environments. You will own coupled thermal–structural analyses to evaluate stress, deformation, and margin of safety for propulsion-adjacent hardware.

Close collaboration with propulsion, thermal, materials, and test teams is required to maintain structural integrity across qualification and flight environments.

Qualifications

• BS or MS in Aerospace Engineering, or related field.
• 5+ years of thermal-structural or thermo-mechanical analysis experience in aerospace.
• Experience performing coupled thermal–structural stress, deformation, and margin of safety analyses.

Responsibilities

• Develop and maintain coupled thermal–structural FEMs for spacecraft hardware in elevated-temperature environments.
• Perform thermo-mechanical stress, distortion, fatigue, and margin-of-safety analyses driven by thermal gradients and transients.
• Evaluate high-temperature material behavior and structural performance using analysis and hand calculations.
• Collaborate with propulsion, thermal, materials, and test teams to validate structural designs for strength and durability.
• Support structural verification through qualification and flight readiness processes.
• Define and execute elevated-temperature material strength testing to support verification.
