Network Architect Engineer Jobs in Michigan (NOW HIRING)

Job Description

The Team:

The Ethernet Systems Engineering team develops, validates, and deploys the in-vehicle Ethernet foundation that enables GM's Software-Defined Vehicle architecture. The team owns end-to-end system engineering for automotive Ethernet networks-including requirements, architecture, network configuration and communication artifacts, higher-layer protocols such as SOME/IP and Service Discovery, test specifications, automation, and network-bench verification-while collaborating closely with electrical architecture, hardware and software teams, semiconductor suppliers, Tier-1 partners, and industry standards organizations.

As part of the broader Embedded Platform Infrastructure Systems Engineering organization, the team helps deliver the reliable, secure, scalable infrastructure capabilities-including communications, diagnostics, safety, cybersecurity, power management, programming, and I/O-that allow vehicle feature teams to build and integrate innovative customer experiences.

The Role:

We are looking for a talented and motivated candidate to join our team in our journey of defining and executing the backbone of our company's future-the next generation Vehicle Electrical and Software Architecture.

The Mechatronics Infrastructure organization is looking for a Senior Software Engineer who will develop work on network validation, scripts, and automation to continuously improve robustness and confidence in our in-vehicle Ethernet network performance. The role will interface with both physical and virtual network test assets, such as single network-devices-under-test benches, networked multi-controller virtual models, transaction-level network simulation models, and physical end-to-end network verification benches.

The role will focus both on functional verification, and its automation, as well as nonfunctional performance metrics such as temporal behavior. The role will cross-collaborate with teams working on embedded software, system specifications, virtual models, test automation infrastructure, and architecture analysis.

What You'll Do (Responsibilities):

• Deploy test automation across physical and virtual test assets, ranging from single-controller benches to complete network benches and models
• Develop solutions for assessment of temporal behavior for a network under test, including performance measurements for single-controller benches, transaction-level models of mixed full-duplex and bus-based automotive Ethernet networks, and precise measurement and regression test of latencies on virtual network models and physical network benches
• Develop test automation for validation of core elements across a full-stack Ethernet solution
• Integrate released software builds and system design artifacts with various network test infrastructure assets (virtual and physical) to increase fidelity of end-to-end network health assessment and to expand our CI/CD test pipeline for system test and regression.
• Perform extensive functional and temporal evaluation of key networking protocols and solutions like gPTP, redundant gPTP, traffic shaping, and redundant communication.
• Evaluate new hardware and software solutions to support technology insertion into next-generation architectures. Examples include, but are not limited to, Differentiated Services in 10BASE-T1S networks, networking IP in MCUs/SoCs, and new RCP (Open Alliance TC18) solutions.

Your Skills & Abilities (Required Qualifications):

• Bachelor's degree in Systems Engineering, Computer Engineering, Electrical Engineering, Computer Science, or relevant discipline.
• Three or more years of experience developing software and validating networks using programming languages such as Python, Rust or C++.
• Knowledge of computer networking protocols, network architecture, and communication standards, including automotive Ethernet technologies and networking stacks like TCP/IP and SOME/IP.
• Knowledge of and experience with software development lifecycle and testing methodologies, network trouble-shooting. simulation and analysis tools, and programming languages.
• Evidence of ability to master new technical areas.

People Skills:

• Strong analytical and problem-solving skills, with ability to see the big-picture perspective.
• Strong communication skills with the ability to, for a wide variety of audiences, adapt the explanation of complex technical concepts.
• Strong teamwork skills to collaborate effectively with peers, cross-functional teams, and stakeholders.

What Will Give You A Competitive Edge (Preferred Qualifications):

• Masters degree in Systems Engineering, Computer Engineering, Electrical Engineering, Computer Science, or relevant discipline.
• Experience with automotive Ethernet switches and networks based on 100/1000BASE-T1 and 10BASE-T1S.
• Advanced knowledge of the internals of the data-link layer components (for example, switch internals and communication software stack).
• Demonstrated experience developing tests for and debugging a complete Ethernet software stack (examples include gPTP, data-link layer prioritization, UDP, TCP/IP, SOME/IP, SOME/IP Service Discovery, DDS, and DoIP).
• Development and use of virtual models for test and validation of embedded software
• Knowledge and end-to-end awareness of the hardware and software components (PHYs, switches, hardware interfaces, connectors, cables, software stack, protocols) that make up a network in the automotive domain. Advanced knowledge of internals of Ethernet switch behavior.
