Onboard Vehicle Network Engineer
Motional · Boston, Massachusetts, United States; Las Vegas, Nevada, United States; Pittsburgh, Pennsylvania, United States; Remote U.S.
About this role
**Mission Summary** Motional’s Platform Infrastructure organization builds and operates the foundational onboard software systems that power our autonomous vehicles. Responsibilities include system communications and IPC, networking, Linux OS development and maintenance, high-speed data logging and offload, and onboard system performance optimization. We’re seeking an **Onboard Vehicle Network Engineer** to lead the design, evolution, and maintenance of our onboard vehicle network architecture. This is a hands-on engineering role where you’ll define network topology, hardware interfaces, communication protocols, and network diagnostics for both current operational vehicles and our next-generation platform—ensuring **high-throughput, low-latency, deterministic, and resilient** communication across onboard compute nodes, sensors, and controllers. **What You’ll Be Doing** - Design and evolve the onboard vehicle network topology (physical + logical) for current and next-generation platforms - Define and implement network protocol stacks, communication standards, and messaging layers across compute nodes, sensors, microcontrollers, and actuators - Write and maintain software and tooling for routing, monitoring, fault detection, diagnostics, and failover handling - Partner with hardware, platform, and autonomy software teams to evaluate and select network hardware components - Establish network performance budgets, **QoS** policies, network isolation/segmentation strategies, and latency/bandwidth constraints - Build telemetry and monitoring tools to track network health, bandwidth utilization, packet drops, and real-time performance - Diagnose and resolve complex networking issues (loss of communication, packet drops, latency jitter, hardware controller errors) - Define maintenance, provisioning, and OTA firmware update strategies for onboard network switches and interface hardware - Contribute to technical roadmaps for next-generation onboard networking and communications infrastructure **What We’re Looking For** - Strong background as a Software Engineer with demonstrated ability to write, debug, and maintain production code - Deep understanding of embedded network architectures, topology design, and system-level communication flows - Hands-on experience with networking protocols/standards (e.g., Ethernet, TCP/IP, UDP, CAN/CAN-FD, etc.) - Proficiency in a modern programming language (**C++ preferred**, but any modern language is acceptable) - Experience designing network security policies, traffic shaping/prioritization, QoS, and logical network isolation - Ability to design and build software (details truncated in the provided description)
