Summary Generated by Built In
Hermeus is a venture-backed defense aviation company reclaiming the lost art of rapid iterative prototyping to build the fastest aircraft in the world today. By prioritizing relentless hardware iteration, we deliver high-speed systems at the pace of the modern battlefield. We work with the Department of War to provide the high-speed capabilities our nation and its allies need to maintain a durable, asymmetric advantage.

About The Role

    We are seeking a DevOps Engineer to support the development, integration, and deployment of flight software systems. This role sits at the intersection of software engineering, infrastructure, and testing, with a strong emphasis on designing and managing Gitlab CI/CD pipelines, enabling automated Flight Test on various Cloud and HW testbeds including Software-in-the-Loop (SIL) and Hardware-in-the-Loop (HIL). 

Responsibilities:

  • Design, implement, and maintain scalable Gitlab CI/CD pipelines to support flight software build, test, and release workflows.  
  • Develop and manage containerized environments using Docker to ensure consistency across development, simulation, and test systems.  
  • Provision and manage cloud infrastructure on Amazon Web Services using Infrastructure as Code with Terraform.  
  • Build and maintain automated pipelines for SIL and HIL testing, enabling continuous validation of flight software against simulated and real hardware interfaces.  
  • Support Flight Test operations by developing reliable deployment, telemetry, and data collection workflows.  
  • Integrate hardware test benches with CI/CD systems to enable automated regression testing and real-time feedback.  
  • Optimize build systems for performance, reproducibility, and traceability across multiple flight software configurations.  
  • Collaborate closely with flight software, avionics, and test engineers to streamline development and test cycles.  
  • Implement monitoring, logging, and alerting solutions for both cloud and on-premise test environments.  

Qualifications:

  • Bachelor’s degree in Computer Science, Software Engineering, Electrical Engineering, Aerospace Engineering, or a related technical field.
  • 3+ years of experience in DevOps, software infrastructure, test automation, or platform engineering.
  • Strong experience designing, building, and maintaining GitLab CI/CD pipelines.
  • Hands-on experience with Docker and containerized development or test environments.
  • Experience provisioning and managing cloud infrastructure, preferably with AWS.
  • Familiarity with Infrastructure as Code tools such as Terraform.
  • Strong scripting or programming experience in Python, Bash, or similar languages.
  • Experience supporting build, test, release, or deployment workflows for complex software systems.
  • Ability to work closely with software, hardware, avionics, and test teams in a fast-paced engineering environment.
  • Strong debugging, troubleshooting, and communication skills.

Preferred Skills and Experience:

  • Experience supporting flight software, embedded software, robotics, aerospace, automotive, defense, or other safety-critical systems.
  • Experience with Software-in-the-Loop, Hardware-in-the-Loop, or other integrated test environments.
  • Familiarity with real-time systems, hardware test benches, avionics systems, or embedded Linux environments.
  • Experience integrating CI/CD pipelines with physical hardware, lab systems, test rigs, or automated regression test infrastructure.
  • Experience with telemetry, data collection, deployment tooling, or operational support for flight test or field test environments.
  • Knowledge of build systems, artifact management, version control, and release traceability for regulated or mission-critical software.
  • Experience implementing monitoring, logging, and alerting for cloud and on-premise infrastructure.
  • Familiarity with AWS services commonly used for compute, storage, networking, security, and automation.
  • Ability to move quickly between infrastructure design, hands-on implementation, debugging, and cross-functional support.
  • Active or previous security clearance, or ability to obtain one.

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.
