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.
The Mission Systems Engineering (MSE) Team develops the Mission Management System (MMS)—a software platform that integrates mission subsystems, autonomy services, operator interfaces, communications links, and telemetry for Hermeus aircraft. The MMS enables rapid incorporation of new capabilities from internal teams and third-party providers. As a Software Engineer on this team, you will design, implement, and test C++ software that extends this platform and interfaces with mission subsystems, autonomy solutions, and external services.
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
