About the role

Architect and design deterministic and Ethernet-based networks that meet the stringent requirements of safety-critical avionics systems.
Serve as the technical authority and point of contact for all networking-related questions across multiple programs.
Capture and translate network-level source requirements into system architecture, interface definitions, and configuration strategies.
Collaborate with internal networking fellows and cross-functional experts to shape the next generation of secure, fault-tolerant avionics networks.
Lead system-level integration, troubleshooting, and verification activities in lab environments.
Drive the development of automated test strategies and tools and ensure robust validation across network interfaces.
Mentor other systems engineers and collaborate closely with hardware, software, and firmware teams to deliver cohesive and scalable system designs.
Contribute to the bid and pursuit process, providing technical insight and proposal leadership for networking solutions.
10-25% of global travel as needed.

Typically requires a degree in Science, Technology, Engineering or Mathematics (STEM) and minimum 8 years prior relevant experience or an Advanced Degree in a related field and minimum 5 years of experience.
U.S. citizenship is required, as only U.S. citizens are authorized to access certain necessary systems.
End-to-end systems engineering experience: requirements definition, design, integration, V&V, and deployment.
Experience with real-time embedded systems, hardware/software interfaces, and systems integration.
Expertise in designing and specifying deterministic network architectures, including but not limited to: Ethernet-based networks (IPv4/IPv6, TSN, VLANs, QoS, multicast).
Deterministic legacy protocols: ARINC 429, MIL-STD-1553, CAN, ARINC 629
Experience configuring and validating network components: switches, routers, NICs, gateways
Strong background in network testing, simulation, and automated scripting (e.g., Python, Bash).
