We are seeking a highly skilled Spacecraft Mechanical Engineer to lead the structural, mechanical, and environmental design of spacecraft systems. This role demands a deep understanding of structural fundamentals, FEA tools, and design for extreme environments such as launch, vacuum, and thermal cycling. You'll play a key role in developing, analyzing, and validating mechanical systems that survive the rigors of launch and thrive in space.

Key Responsibilities

• Develop and analyze spacecraft structures using SolidWorks, ANSYS, or similar FEA tools.

• Perform hand calculations and assisted modeling to validate load paths, margins, and design safety factors.

• Create detailed drawings, assemblies, and manufacturing specifications.

• Design for and validate against launch vehicle load profiles and shock/vibration environments.

• Develop and manage vibe table test plans, including test fixture design and interface requirements.

• Lead and execute hardware qualification campaigns including structural and mechanical tests.

• Select materials and finishes compatible with vacuum, radiation, and thermal cycling.

• Conduct pattern-of-life studies to model long-term performance degradation and component reliability.

• Interface with thermal, avionics, and optical engineering teams to ensure system-wide compatibility and performance.

• Own mechanical interfaces and integration with spacecraft buses, enclosures, and payloads.

Basic Qualifications

• Bachelor’s or Master’s degree in Mechanical Engineering, Aerospace Engineering, or related field.

• 5+ years of hands-on experience in spacecraft or high-reliability mechanical design.

• Proficiency with SolidWorks, ANSYS, or equivalent CAD/FEA tools.

• Experience validating mechanical systems against vibration, shock, and launch loads.

• Strong understanding of structural mechanics, thermal expansion, and fatigue analysis.

• Familiarity with vacuum-compatible materials, coatings, and thermal interfaces.

• An iterative mindset- perfect is the enemy of good.

• Ability to thrive in a fast paced dynamic environment where rapid prototyping is the norm.

Preferred Qualifications

• Experience using Thermal Desktop, RadCAD, or similar tools for spacecraft thermal modeling.

• Background in STOP (Structural, Thermal, Optical Performance) analysis for precision optical payloads.

• Experience supporting flight hardware integration and on-orbit performance verification.

• Working knowledge of ECSS, NASA GEVS, or equivalent test standards.
