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
