Responsibilities
Design, analyze, and optimize active and passive thermal control systems for high-altitude aerospace platforms
Perform steady-state and transient thermal analyses using analytical and numerical methods
Develop, validate, and maintain thermal models predicting system behavior across stratospheric and mission-specific operating conditions
Support selection, qualification, and trade studies for materials, insulation, coatings, radiators, and thermal interfaces
Define thermal requirements, margins, and operating limits for avionics, batteries, payloads, and structural components
Support environmental testing, including thermal vacuum, altitude simulation, and temperature cycling tests
Analyze test data, correlate results with thermal models, and drive design updates as needed
Collaborate with mechanical, electrical, systems, and manufacturing teams to resolve real-world thermal challenges
Document designs, analyses, test results, and compliance with applicable engineering standards
Support design reviews, risk assessments, and continuous improvement initiatives
Qualification
Required
Bachelor's degree in Mechanical Engineering, Aerospace Engineering, or a closely related field
5–10 years of demonstrated, hands-on experience in thermal analysis and thermal system design for aerospace or high-altitude flight systems
Proven practical experience supporting thermal management for drones, HAPS, UAS, or closely related aerospace platforms
Demonstrated ability to independently own thermal analyses and provide clear, experience-based recommendations to engineering leadership and cross-functional teams
Strong, applied understanding of heat transfer principles (conduction, convection, radiation), particularly in low-density, high-altitude environments
Experience developing, validating, and correlating thermal models using industry-standard tools (e.g., ANSYS, Thermal Desktop, COMSOL, or equivalent)
Experience supporting hardware through design, test, integration, and operational readiness, not solely academic or theoretical work
Ability to operate effectively in a fast-paced, R&D-driven aerospace environment
Strong analytical, problem-solving, and technical documentation skills
Preferred
Master's degree in Mechanical or Aerospace Engineering
Direct experience with high-altitude platforms, stratospheric vehicles, or long-duration unmanned flight systems
Hands-on experience with thermal vacuum testing, environmental qualification, or flight validation campaigns
Knowledge of lightweight structures, composites, and advanced aerospace materials
Experience supporting mission-critical or flight-certified hardware
