• 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.

• 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.

Preferred Qualifications:

• 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.
