Applications will be accepted on an ongoing basis until the requisition is closed.At Blue Origin, we envision millions of people living and working in space for the benefit of Earth. We’re working to develop reusable, safe, and low-cost space vehicles and systems within a culture of safety, collaboration, and inclusion. Join our team of problem solvers as we add new chapters to the history of spaceflight!
The role is part of the In-Space Systems business unit, which is focused on addressing two of the most compelling challenges in spaceflight today: space infrastructure and increasing mobility on-orbit.THERMAL & MATERIALS ENGINEER – SPACE OPTICS
Location: Longmont, CO (Onsite)
Role Summary:
The Thermal & Materials Engineer will own the thermal architecture, athermalization, materials selection, and contamination control for the payload. This role is responsible for ensuring the optical system maintains performance across all mission environments. Your expertise in thermal management and space-grade materials will be crucial to developing a robust design that is ready for production.
Special Mentions:
Relocation assistance may be available for this position
Travel expectations: Occasional travel may be required for technical reviews and test campaigns
Responsibilities include but are not limited to:
Thermal Architecture & Athermalization
Develop and close the thermal portion of Structural-Thermal-Optical Performance (STOP) models to predict thermal-induced Wavefront Error (WFE) and Line-of-Sight (LOS) drift
Design athermal interfaces (CTE matching, flexures) for optics on benches, ensuring they are manufacturable and repeatable in production
Design active thermal management for optical subsystems
Materials, Contamination, and DFM
Select materials, adhesives, and coatings for space use that meet outgassing requirements and are suitable for volume manufacturing
Define production-scalable processes for bakeout, adhesive cure schedules, and handling time windows to minimize contamination risk
Own the contamination control plan, ensuring its practical implementation on the production floor
Test & Verification
Author Thermal Vacuum (TVAC) test profiles and instrumentation plans to validate thermal models and system performance
Support pre/post-environment optical re-verification, analyzing data to confirm thermal design margins
