Senior Mission Systems Software Engineer (C2)

Role Summary:
The Senior Mission Systems Engineer is responsible for designing, developing, testing, and maintaining high-performance mission-critical software that supports fire control, flight, ground, and command-and-control systems. This role focuses on building robust, secure, and reliable modern C++ applications for Linux-based embedded and edge computing platforms while integrating with sensors, hardware, and distributed networked systems.

The ideal candidate possesses deep expertise in modern C++, Linux, networking, and systems engineering, with the ability to troubleshoot complex issues spanning software, hardware, networking, and deployment environments. Success in this role requires close collaboration with cross-functional engineering teams—including mechanical, electrical, guidance, navigation and control (GNC), and operations—to deliver reliable mission capabilities from development through field integration.

Candidates should have strong computer science fundamentals, experience with embedded and distributed systems, and a security-first approach to software design and implementation. Experience with robotics, command-and-control systems, fire control, flight software, cybersecurity, applied mathematics, and modern software architectures is highly desirable. The role also includes occasional travel (up to 20%) to support customer demonstrations, system integration, and field testing

Responsibilities:

• Design, implement, test, and maintain high-quality modern C++ software for mission systems.
• Contribute to fire control, ground systems, and flight software efforts.
• Refactor and improve existing software architecture, reliability, maintainability, and testability.
• Work with linux-based systems deployed on embedded and edge compute platforms.
• Interface with hardware-adjacent systems, sensors, and embedded compute.
• Build software that communicate over real-world networks, including unreliable or constrained data links.
• Debug complex system-level issues across software, hardware, networking, and deployment environments.
• Collaborate with mechanical, electrical, software, GNC, and operations teams towards a common goal.
• Support occasional field testing, integration events, and customer demonstrations.
• Apply a security-oriented mindset to system design, implementation, deployment, and debugging.
• Travel up to 20% of the time for on-site integration events with external vendors or customers.

Required Qualifications:

• Strong Modern C++ (23) experience or demonstrable ability to write high-quality C++
• Strong CS fundamentals: data structures, algorithms, concurrency, memory management, networking, and debugging
• Linux experience: Linux development, debugging, deployment, operation, maintenance
• Networking experience: TCP/UDP, routing, multicast, DNS, DDS, pub/sub, Ethernet, etc
• Understanding of hardware-adjacent software: communication protocols, sensors, etc
• Ability to obtain and maintain a U.S. security clearance
• Willingness to travel for up to 20% of the job

Preferred Qualifications:

• C++23/C++23 experience
• Robotics experience (ROS/ROS2, control algorithms, path planning, etc)
• C2 (Command and Control) software experience
• Fire control systems (FCS) software experience
• Flight software (FSW) software experience
• Nix/NixOS experience
• Cybersecurity mindset: defense in depth, secure-by-default design, threat modeling, CTF/security background, crypto familiarity, hardening experience
• Applied math background: linear algebra, optimization, estimation, controls, simulation, numerical methods, etc
• Basic API/web literacy: REST, gRPC, protobuf, frontend/backend concepts, databases, etc
