Analyze and test novel ways to reduce thermal-induced stress and deflections in hot metallic structures.
Collaborate with multidisciplinary engineering teams, including aerodynamics, propulsion, structures, and materials, to integrate thermal solutions into the overall vehicle design.
Plan, conduct, and analyze thermal tests in laboratory environments and during flight tests to validate thermal models and verify the performance of thermal systems under real-world conditions.
Keep up to date with advancements in thermal engineering, aerospace materials, and heat transfer technologies, and seek approaches to improve thermal efficiency and performance.
Prepare technical documentation, reports, and presentations to communicate thermal analysis results, design decisions, and recommendations to stakeholders and project teams.
Work with responsible engineers to develop simple and robust thermal solutions for high-temperature environments.

Desired Qualifications

A master's degree is advantageous.
Strong analytical and problem-solving skills to address complex thermal challenges and propose effective solutions.
Ability to collaborate with cross-functional teams and present technical information clearly and concisely.
Adaptability and willingness to work in a fast-paced and dynamic research and development environment.

About the Company

Hermeus

Develops hypersonic defense aircraft and engines

Hermeus designs and builds high-Mach and hypersonic aircraft for defense, using uncrewed test platforms and a reusable propulsion system. Its core approach centers on the Quarterhorse testbed and the Chimera engine, a turbine-based combined cycle that starts in a turbojet mode for runway takeoff and transitions to a ramjet for speeds above Mach 5. The company differentiates itself with rapid, hardware-focused prototyping drawn from a spaceflight background and a clear path to production through government contracts with the DoD, DIU, and ABMS programs. Its near-term goal is to mature Quarterhorse and Darkhorse into production-capable systems for defense missions, while its long-term vision includes Halcyon, a 20-seat commercial airliner flying transatlantic routes in about 90 minutes.

Company size: 201-500
