Software Engineer - Mission Systems

AtlantaOn-siteFull-time

AI Summary

Software Engineer on the Mission Systems team designs, implements, and tests C++ software to extend the Mission Management System and interface with mission subsystems, autonomy solutions, and external services.

About this role

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 (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
