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

~3 min read

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.

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

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

Ability to clearly communicate technical decisions, risks, and tradeoffs across multidisciplinary teams

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

Experience with RF communications, SATCOM, line-of-sight radios, or tactical datalinks

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

Linux software development and deployment experience

Experience developing fault-tolerant or degraded-mode behaviors for distributed systems

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

Experience establishing technical direction or influencing execution across multiple teams

Experience working in a startup or rapid-prototyping environment
