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.

• Develop and analyze spacecraft structures using Solid Works, 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.

• 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 Solid Works, 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.

• 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.

• Competitive Compensation – A salary package aligned with industry standards and your experience.
• Equity Opportunities – Take part in our success with stock options.
