This role requires strong hands-on capability, analytical rigor, and the ability to move quickly between test operations, data interpretation, and hardware problem-solving. You will play a critical role in increasing engine development velocity and reliability.
Responsibilities
- Own development engine test campaigns from planning through execution and post-test analysis
- Define, author, and refine engine test plans, procedures, and setpoints aligned with program objectives
- Support and make decisions during live test operations, including hot-fire and subsystem testing
- Identify, diagnose, and resolve test-related engine issues across hardware, instrumentation, and procedures
- Standardize and improve test data review, reduction, and reporting processes
- Develop Python-based tools for data processing, visualization, and automated analysis
- Translate test data into clear engineering insights, including performance characterization and root cause analysis
- Drive post-test reviews and ensure actionable outcomes are captured and executed
- Participate in hands-on engine build, integration, and test setup activities
- Author and maintain development engine work instructions, test procedures, and technical documentation
- Generate, track, and resolve engineering issues through ticketing systems
- Collaborate cross-functionally with design, manufacturing, avionics, and test teams to resolve system-level challenges
- Ensure proper sensor selection, instrumentation setup, and data integrity during test campaigns
- Contribute to continuous improvement of test infrastructure, tooling, and development processes

Hermeus Insights
What We Do
Hermeus is a high-speed aircraft manufacturer focused on the rapid design, build, and test of high-Mach and hypersonic aircraft for the national interest. Working directly with the Department of Defense, Hermeus delivers capabilities that will ensure that our nation, and our allies, maintain an asymmetric advantage over any and all potential adversaries. Utilizing an integrated, hardware-rich, iterative development approach to aircraft design and build, Hermeus aims to deliver advanced air power at a pace not seen in the U.S. since the 1950s. Hermeus’ current Quarterhorse Program is actively unlocking unmanned high-speed flight. One program, four aircraft – each purpose-built to unlock a specific technical challenge, advance learnings, and incrementally de-risk critical technology in the pursuit of hypersonic aircraft. Today, Hermeus is building its second Quarterhorse vehicle, Mk 2, after having designed, built, and flight tested its predecessor, Mk 1, in 18 months. Capable of reaching speeds of Mach 3+, Quarterhorse Mk 2 will be the fastest uncrewed military aircraft in service for national defense. The final iteration of Quarterhorse, Mk 4, will be capable of transitioning from turbofan to ramjet mode utilizing a Hermeus-developed turbine-based combined cycle (TBCC) propulsion system to achieve sustained speeds of Mach 5+. Hermeus' approach of build-fly-build lays the groundwork for unlocking hypersonic flight at a pace and cost previously deemed impossible. America needs fast planes fast – and Hermeus is delivering them.
Why Work With Us
We prioritize hardware and people. Cutting-edge technology is only made possible by bringing together a world-class team. At Hermeus, you will be challenged – but also empowered. We encourage calculated risks taking and learning from our mistakes. Iteration is the name of the game.
