This position is ideal for a C++ generalist who thrives on tackling complex challenges in systems and systems integration. If you enjoy building cross-language software, improving CI\/CD pipelines, and integrating distributed real‑time systems, you’ll find this role rewarding. Join a team that’s driving innovation through robust software engineering and practical integration work across simulation environments, third‑party systems, and development workflows.

What You’ll Do:

• Design, implement, and maintain C++ and Python software in support of complex, cross‑platform systems.
• Contribute to system architecture with a focus on performance, maintainability, and integration.
• Develop and support APIs and messaging interfaces (e.g., gRPC, REST, ZeroMQ). Integrate third‑party software and hardware systems, including real‑time and simulation tools.
• Debug and support distributed systems, with attention to threading, timing, and data flow.
• Apply modern agile practices such as test‑driven development, continuous integration, and automated testing.
• Improve and maintain CI\/CD workflows using tools like GitLab CI, Docker, CMake, and Conan.
• Collaborate across teams and projects to share solutions and promote good software practices.
• Continuously learn and adapt to new tools, standards, and technologies.

Required Qualifications:

• Typically requires a minimum of 5 years of related experience with a Bachelor’s degree; or 4 years and a Master’s degree; or 2 years with a PhD; or equivalent work experience.
• Strong proficiency in modern C++ (C++14/17/20) with the ability to work effectively in legacy codebases (C++98/03).
• Proficiency in Linux\/Unix environments, including system‑level development and debugging tools.
• Experience with Python.
• Professional experience in Linux environments (Windows experience is a bonus).
• Solid understanding of system‑level engineering and design patterns.
• Experience in a collaborative environment with CI\/CD and test automation.
• Experience with containerization technologies such as Docker.
• Active SECRET clearance.

Preferred Qualifications:

• Experience integrating distributed simulation environments such as AFSIM or NGTS.
• Familiarity with open standards like UCI and OMS, and an understanding of data buses and interface protocols common in avionics and aircraft systems.
• Familiarity with simulation tools and modeling frameworks.
• Experience with networking concepts and messaging infrastructure.
• Hands‑on experience with CMake, Conan, and GitLab CI\/CD pipelines.
• Exposure to real‑time systems and hardware\/software integration.
