Responsibilities:
- Design, implement, and maintain C++ software components that extend and evolve the Mission Management System platform
- Integrate third-party mission subsystems, autonomy solutions, and communications services by defining new interfaces, data models, and messaging pathways
- Work with systems, avionics, and network engineers to establish interfaces, data schemas, and protocols across mission systems
- Develop software requirements, architecture artifacts, and integration documentation as the system and platform mature
- Implement mission workflows, operator interaction logic, and data transformation services supporting command, control, and telemetry
- Participate in code reviews, integration builds, simulations, and system-level validation activities
- Identify, diagnose, and resolve software and integration issues in distributed, hardware-connected environments
- Contribute to simulation and hardware-in-the-loop environments for capability validation
Qualifications:
- Bachelor’s degree in Computer Science, Computer Engineering, Software Engineering, or a related technical field
- 5+ years of professional C++ development experience delivering production-quality software
- Proficiency with modern C++ (C++14/17/20), including concurrency, memory management, and performance-oriented programming
- Experience with network programming concepts such as TCP, UDP, and multicast at the socket interface level
- Experience integrating software with hardware systems or external services in environments with evolving requirements
- Ability to define interfaces, protocols, and system boundaries where none exist
- Strong communication and collaboration skills
Preferred Skills and Experience:
- 10+ years of C++ development experience building complex, distributed, or real-time systems
- Experience developing mission systems, operator-facing software, mission planning tools, or telemetry visualization systems
- Experience with RF, SATCOM, LOS radios, or tactical datalink systems
- Familiarity with publish/subscribe or messaging middleware (e.g., DDS, ZeroMQ, ActiveMQ, Kafka)
- Understanding of avionics architectures, autonomy frameworks, or integration of third-party mission subsystems
- Experience in regulated or safety-critical environments (e.g., DO-178C, ARINC standards, MIL-STD interfaces)
- Strong debugging and test experience, including simulation or hardware-in-the-loop environments
- Experience working in a startup or rapid development environment

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.
