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. As a Software Engineer on the Mission Systems Engineering Team, you will design, implement, and test C++ software for the Mission Management System, integrating various mission subsystems 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:
Required:
• 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:
• 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
