Senior Spacecraft Thermal Engineer Seen this week
About Observable Space
Observable Space builds precision optics platforms for Earth and space observation. We deliver opto-mechanical hardware, embedded computing, and cloud orchestration systems trusted by NASA, JPL, SpaceX, Boeing, and the US DoD.
The Role
We're seeking a Senior Spacecraft Thermal Engineer to design and develop thermal control systems for telescope platforms and spacecraft. You'll work with optical, electrical, mechanical, and software engineers to ensure thermal stability and performance for ground-based and space-based systems.
Key Responsibilities
- Design and optimize thermal control systems (radiators, heaters, insulation, thermal straps, enclosures)
- Develop thermal models and perform steady-state and transient thermal analysis
- Perform STOP analysis (Structural, Thermal, Optical Performance) to verify thermal stability and optical impact
- Conduct FEA simulations for thermal, structural, and environmental conditions
- Collaborate with optics, mechanical, and electrical teams on thermal integration
- Define thermal requirements, margins, and verification strategies
- Support environmental testing including thermal vacuum (TVAC) and thermal cycling
- Support full product lifecycle from concept design through production
- Participate in design reviews (PDR, CDR) and documentation
- Provide engineering support during fabrication, integration, and validation
Basic Qualifications
- Bachelor's degree in Mechanical Engineering, Aerospace Engineering, or equivalent
- 5+ years thermal engineering experience in aerospace or high-performance systems
- Strong understanding of heat transfer fundamentals (conduction, convection, radiation)
- Experience with thermal analysis tools (Thermal Desktop, SINDA/FLUINT, ANSYS, or similar)
- Experience developing and validating thermal models for complex systems
- Effective communicator and collaborator
- Demonstrated passion for aerospace or observational technologies
Preferred Qualifications
- Experience with spacecraft thermal control systems and space environments (LEO, GEO, deep space)
- Understanding of FEA (ANSYS, Nastran), tolerance analysis, and DFM principles
- Experience with thermal vacuum (TVAC) testing, thermal cycling, and model correlation
- Knowledge of materials, coatings, surface properties, and thermal interface design
- Understanding of system engineering workflows, interface control documents, and verification
- Experience in fast-paced early-stage or startup environments
- Basic scripting or automation (Python, MATLAB) for thermal modelling or data analysis
What We Offer
- Competitive salary aligned with industry standards and experience
- Stock option equity opportunities
- Hybrid work setup with minimum 3 days per week in Los Angeles office
- Unlimited PTO including paid holidays
- Comprehensive medical, dental, and vision coverage (100% employer-paid)
- Latest hardware and software tools
- Mission-driven culture focused on real-world impact
- Inclusive and diverse workplace
