Job description

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: The Mission Systems Engineering team develops the Mission Management System—the software platform connecting mission subsystems, autonomy services, operator interfaces, communications links, and telemetry across Hermeus aircraft and ground systems.  As a Senior/Principal Mission Software Engineer, you will architect, build, integrate, and validate critical portions of this platform. You will work across software, avionics, communications, autonomy, simulation, and flight operations to solve complex problems in distributed, hardware-connected environments.  This is a hands-on technical leadership role with the opportunity to define foundational architecture and directly influence how Hermeus aircraft are commanded, monitored, tested, and expanded with new mission capabilities. Responsibilities:

  • Own major Mission Management System capabilities from architecture through integration, testing, and operational use

  • Design and develop high-performance C++ software for command and control, telemetry, mission workflows, and subsystem coordination

  • Define scalable architectures, interfaces, APIs, protocols, and message schemas

  • Integrate autonomy services, sensors, payloads, radios, tactical datalinks, and third-party systems

  • Make technical decisions involving performance, reliability, latency, fault tolerance, and extensibility

  • Diagnose complex issues across distributed software, networks, embedded hardware, avionics, and communications systems

  • Partner with systems, avionics, autonomy, networking, flight-test, and operations teams

  • Build and improve simulation, software-in-the-loop, hardware-in-the-loop, and system-integration environments

  • Lead design reviews, code reviews, technical trade studies, and integration activities

  • Identify technical risks and drive solutions in environments where requirements are still evolving

  • Mentor engineers and establish strong software architecture and development practices

  • Support ground and flight-test campaigns, including real-time troubleshooting

Requirements:

  • Bachelor’s degree in Computer Science, Computer Engineering, Electrical Engineering, Software Engineering, or a related field

  • 7+ years of professional software-development experience for Senior-level consideration

  • 10+ years of relevant experience, or an equivalent record of technical leadership and impact, for Principal-level consideration

  • Advanced proficiency with modern C++, including C++17 or newer

  • Experience designing and delivering complex, production-quality software systems

  • Strong knowledge of concurrency, memory management, software architecture, and performance-oriented development

  • Experience with distributed, real-time, embedded, robotic, aerospace, or other hardware-connected systems

  • Experience with TCP, UDP, multicast, and socket-level network programming

  • Ability to define architectures, interfaces, protocols, and system boundaries in ambiguous environments

  • Experience integrating software with hardware, external services, or independently developed subsystems

  • Strong debugging skills across software, networking, and hardware interfaces
