Qualifications

• Advanced experience designing and maintaining large C++ systems.
• Fluency in C++14/17/20 with legacy codebase familiarity.
• Proficiency in Linux/Unix development and debugging tools.
• Strong systems integration with distributed systems and real-time processing.
• CI/CD experience, containerization (Docker), and build tooling (CMake, Conan).
• Proficiency in Python and scripting/automation tools.
• Active SECRET clearance and ability to obtain TS/SCI clearance.
• Experience mentoring teams and leading multi-contributor efforts.

Responsibilities

• Architect and implement high-performance C++ and Python systems across cross-platform environments.
• Lead design and integration of distributed systems, simulation tools, and third-party hardware/software.
• Define and enforce technical direction, design patterns, and integration practices.
• Guide teams in building robust messaging and API layers (gRPC, REST, ZeroMQ).
• Own CI/CD pipelines using GitLab CI, Docker, Conan, and CMake.
• Lead debugging and optimization of real-time and multi-threaded systems.
• Drive end-to-end integration across simulation and operational systems.
• Mentor engineers and contribute to tooling and process improvements.
• Evaluate new technologies to improve performance, stability, and developer efficiency.

Job description

Job Summary

This role is for a seasoned C++ generalist and systems integrator who thrives at the intersection of software, infrastructure, and integration. You’ll lead complex technical efforts across distributed systems and simulation environments, with minimal oversight. Your work will shape foundational capabilities that power autonomy, simulation, and real-time system interfaces across multiple platforms.

Responsibilities

• Architect and implement high-performance C++ and Python systems across cross-platform environments.
• Lead the design and integration of distributed systems, simulation tools, and third-party hardware/software.
• Define and enforce technical direction, design patterns, and integration practices across projects.
• Guide teams in building robust messaging and API layers (e.g., gRPC, REST, ZeroMQ) that bridge critical system components.
• Own the evolution and support of CI/CD pipelines using GitLab CI, Docker, Conan, and CMake.
• Lead debugging and optimization of real-time and multi-threaded systems across a range of domains.
• Drive end-to-end integration efforts, including planning, implementation, and verification across simulation and operational systems.
• Serve as a force multiplier by mentoring other engineers and contributing to shared tooling and process improvements.
• Evaluate and incorporate new technologies that improve system performance, stability, and developer efficiency.

Qualifications

• Typically requires a minimum of 7 years of related experience with a Bachelor’s degree; or 5 years and a Master’s degree; or 4 years with a PhD; or equivalent work experience.
• Advanced experience designing and maintaining large C++ systems, with fluency in C++14/17/20 and comfort navigating legacy C++98/03 codebases.
• Proficiency in Linux/Unix environments, including system-level development and debugging tools.
• Strong systems integration background with practical experience in distributed systems, real-time processing, and hardware/software interfaces.
• Significant experience with CI/CD systems, containerization (e.g., Docker), and build tooling (e.g., CMake, Conan).
• Proficiency in Python and familiarity with other scripting and automation tools.
• Deep knowledge of Linux environments (Windows experience is a bonus).
• Demonstrated success leading efforts involving 10+ contributors, including technical planning and mentorship.
• Strong understanding of networking concepts and communication protocols.
• Active SECRET clearance.
• Real-time or distributed simulation experience (e.g., AFSIM, NGTS, or similar).
• Familiarity with message-passing infrastructure and web-service technologies like gRPC, REST APIs, and message queues.
• Familiarity with open standards like UCI and OMS, and an understanding of data buses and interface protocols common in avionics and aircraft systems.
• Experience integrating simulation with autonomy frameworks or real-time operators.
• Experience developing and integrating with modeling or analysis pipelines.
• Ability to obtain a TS/SCI clearance.
