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.
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.
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
Bachelor’s degree in Computer Science, Computer Engineering, Electrical Engineering, Software Engineering, or a related field
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
Ability to define architectures, interfaces, protocols, and system boundaries in ambiguous environments
Demonstrated ownership through design, implementation, integration, testing, and deployment
Experience with mission systems, command-and-control software, mission planning, ground-control systems, autonomy platforms, or operator-facing applications
Aerospace, defense, robotics, autonomous vehicle, or spacecraft experience
Familiarity with publish/subscribe architectures or middleware such as DDS, ZeroMQ, ActiveMQ, or Kafka
Experience integrating third-party sensors, payloads, autonomy services, radios, or mission subsystems
Knowledge of avionics architectures, aircraft networks, telemetry, and command-and-control workflows
Experience with simulation, SIL, HIL, system-integration labs, ground tests, or flight tests
Familiarity with standards such as DO-178C, ARINC, FACE, OMS/UCI, STANAG, or MIL-STD
