Mechanical Engineer, Spacecraft Structures

From telescopes to software architecture, Observable Space provides the foundational elements every organization needs to operate in space. Observable Space is unlocking continuous, real-time observations of space with the industry’s first line of vertically integrated hardware and software products. The company is the result of a merger between PlaneWave Instruments, the leader in advanced telescope design and manufacturing in the US, and OurSky, a company founded by SpaceX’s former VP of software engineering to create a developer platform for space data applications. Observable Space’s full line of products serves all sectors of the space industry including commercial, science, education, and government customers, as well as astronomy enthusiasts discovering the cosmos.

Observable Space is backed by top institutional investors–Upfront Ventures, Oceans Ventures, Venrex, Marlinspike Partners, and Embedded Ventures.

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.

• Cross-Functional Collaboration

• 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.

• Understand that perfect is the enemy of good

• 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.

What We Offer

• Competitive salary and generous benefits package.

• Premier health benefits (medical, dental, and vision) covered 100% for the employee and 80% for family (for US employees; alternative options available for international employees)

• Flextime PTO with a required minimum of three weeks vacation.

• Opportunity to work on groundbreaking projects in a highly innovative environment.

• A collaborative and inclusive culture that fosters professional growth and development.
