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

Minimum Qualifications

• BS/MS in Mechanical, Aerospace, or Materials Engineering
• 5+ years in thermal design and analysis for optical payloads or complex space hardware
• Experience with heaters, Multi-Layer Insulation (MLI), and TVAC test operations
• Expertise in materials/outgassing, adhesive selection, bakeout planning, and contamination control for space applications

Preferred Qualifications

• Experience with STOP analysis and thermal-structural FEA coupling
• Knowledge of how production process variations (e.g., bondline thickness, coating application) impact thermal performance
• Familiarity with thermal management for fiber optics and lasers
