Job description
Special Mentions
Location: This role can be based at any of the following Blue Origin locations: Denver, CO; Los Angeles, CA; Space Coast, FL; Reston, VA; Huntsville, AL; or Kent, WA (Seattle area).
Relocation: Relocation assistance is available for candidates relocating to one of the primary Blue Origin office locations.
Travel: Up to 25% travel may be required depending on work location and program needs.
Responsibilities Include But Are Not Limited To
Lead thermal design & analysis for satellite-based, high-power payloads and associated power electronics.
Develop detailed thermal models using tools such as Thermal Desktop, SINDA/FLUINT, or equivalent, covering conduction, radiation, and convection regimes as appropriate.
Define and manage thermal interfaces across payload subsystems, including radiators, heat pipes, loop heat pipes, cold plates, and structural elements.
Perform transient and steady-state thermal analyses to validate performance under mission profiles, including peak duty cycles, eclipse transitions, and worst-case environmental conditions.
Develop thermal architecture for common bus/payload configurations reused across a production block, including tailoring for orbit plane, beta angle range, and payload variant.
Select and defend the appropriate thermal qualification, margin, and acceptance approach (e.g., protoflight, workmanship-only TVAC on subsequent units, thermal cycling screening, lot acceptance sampling) based on build rate, mission class, and design life; tailor requirements per SMC-S-016 / MIL-STD-1540 as applicable.
Define thermal model correlation strategy under limited test data, extending correlated models across the rest of a production block.
Address LEO thermal cycling fatigue over high cycle counts (~5,000+ eclipse cycles/year) on joints, solder, TIMs, and coatings across design life.
Drive design-for-manufacturability of thermal hardware at rate (e.g., MLI touch labor, coating repeatability, TIM dispensing, heater and thermostat installation), leveraging parametric or automated thermal modeling workflows to support rapid trades.
Evaluate COTS or commercial-grade thermal components where mission class permits, and manage heater power budget as a fleet-level EPS driver, trading heater sizing against battery and array mass.
Support design-for-demise and material selection for disposal casualty risk (ODMSP).
Assess manufacturability, cost, and schedule impact of thermal hardware choices (radiators, heat pipes, loop heat pipes, cold plates) for production at scale.
Support thermal design and analysis concurrently across multiple constellation and payload programs, prioritizing effort against shifting schedules and design maturity.
Collaborate closely with payload subject matter experts, mechanical, power, and systems engineering teams to ensure thermal constraints are integrated into payload element layout and packaging.
Establish thermal requirements, margins, and verification plans aligned with mission reliability and lifetime goals.
Drive thermal design trades balancing performance, mass, power consumption, manufacturability, and cost for both space and ground systems.
Contribute to major technical design reviews and serve as a key technical authority for the thermal system.
Mentor junior engineers and contribute to organizational best practices in thermal engineering.
Minimum Qualifications
Bachelor's degree in mechanical engineering, aerospace engineering, physics, or related field.
7+ years of experience in thermal engineering for aerospace systems and/or high-performance electronics.
Demonstrated experience with spaceborne thermal design, including vacuum environments, radiation heat transfer, and flight hardware qualification.
Experience with thermal modeling tools (e.g., Thermal Desktop, SINDA/FLUINT, ANSYS Icepak, or equivalent).
Knowledge of materials, coatings, and thermal interface technologies suitable for space systems.
Familiarity with environmental standards (e.g., NASA, ESA, MIL-STD) and qualification testing.
Exceptional communication skills, with a demonstrated ability to influence and guide multidisciplinary teams.
Ability and willingness to obtain and maintain a TS//SCI security clearance.
Must be a U.S. citizen or national, U.S. permanent resident (current Green Card holder), or lawfully admitted into the U.S. as a refugee or granted asylum.
Preferred Qualifications
Master's or PhD degree in mechanical engineering, aerospace engineering, physics, or related field.
Active TS//SCI clearance.
Experience supporting capture and proposal efforts for new business opportunities, including contributing technical content and solutions to winning pursuits.
Background in space-based antenna systems or similar high-power payload systems.
Experience with thermal management of high-power-density electronics such as T/R modules, phased array apertures, or laser communication terminals.
Experience with advanced cooling techniques, including loop heat pipes, vapor chambers, and liquid cooling systems.
Experience on a proliferated LEO or other high-rate satellite program.
Experience with thermal cycling / ESS / HALT-HASS-style screening, including safety-of-screen or damage accumulation analysis.
