Staff Systems Architect – Body Controls Co-Simulation Job at General Motors (Markham)

Job Description

General Motors is transforming how we develop and validate vehicle Body embedded controls and software as we move toward our Zero Crashes, Zero Emissions, Zero Congestion vision. We are seeking a Staff Systems Architect – Body Controls Co‑Simulation to lead the technical architecture of our Body domain Co-Simulation (CoSim) environments within the Virtualization & SIL Integration (VnSI) organization. In this role, you will own the end‑to‑end CoSim architecture for Body controls (vehicle access, cabin thermal, occupant positioning, occupant protection, lighting, visibility, vehicle state, and related functions), define and govern CoSim packages, and lead variant and configuration management across programs and model years. You will partner closely with Software‑in‑the‑Loop (SIL) Simulation Integration Engineers (SIEs) and Dev Leads, System Integration Architects, Software Architects, and SW Quality Architects to ensure our CoSim solutions are scalable, robust, and fully integrated into continuous integration (CI) pipelines for GM’s Software Defined Vehicle (SDV) Architecture.

Job Responsibility

Provide technical and architectural leadership for body controls Co-Simulation across the VnSI Body Domain, setting the long‑term vision and roadmap for CoSim capabilities and infrastructure.
Define and maintain a high‑level CoSim architectural design for body controls, comprehending functional and non‑functional requirements (performance, fidelity, scalability, reusability, maintainability) and aligning with SDV and Mechatronics Infrastructure direction.
Define the variant & configuration management strategy for CoSim packages across programs, regions, model years, and option content (e.g., trim levels, content packages, regulatory variants).
Lead and influence stakeholders (Software, product, program, systems teams) to ensure Body CoSim architecture is understood, adopted, and used consistently across programs.
Collaborate with System Engineers and SIEs to define SIMBOMs (CoSim Bills of Materials) that map program test requirements and feature content into concrete CoSim assets for each configuration.
Establish and maintain standards for CoSim package structure, documentation, versioning, and release notes to ensure traceability and ease of deployment across SIL environments and CI pipelines.
Work with Mechatronics Infrastructure, SDV Network, and Body Controls teams to ensure supplier and internal virtual ECU deliveries integrate cleanly into the CoSim packages and support GM network and diagnostic requirements.
Own the CoSim architecture for RestBus and behavioral modeling, defining how networks, ECUs, and vehicle behaviors are represented in simulation.
Define RestBus architecture patterns for communication networks (CAN/LIN/Ethernet) including signal ownership, gateway behavior, timeouts, diagnostics, wakeup/sleep behavior, and performance budgets.
Ensure CoSim architectural compatibility across SIL, HIL, VEOS, and HPC deployments.
Define CoSim architectural enablers required to support Continuous Integration / Continuous Delivery (CI/CD) for virtual ECUs and CoSim packages, and work with Other System Architects and leadership to implement them incrementally.
Partner with pipeline and tools teams to align CoSim packages with CI quality gates (e.g., build, smoke tests, regression suites, coverage criteria) and ensure failures are actionable by teams.
Support L4 vECU architecture and performance strategies, including event-driven simulation patterns, scheduling strategies, and core partitioning.
Provide architectural guidance and mentoring to SIEs, software developers, and test engineers on CoSim modeling patterns, RestBus design, variant/configuration practices, and SDV concepts.
Contribute to, and in some cases lead, training and lunch‑and‑learn sessions on CoSim architecture, CoSim packaging, configuration management, and CI practices.

Requirements

Bachelor’s degree in Electrical / Computer / Mechatronics Engineering, Computer Science, or related field.
10+ years of relevant experience in embedded software, systems engineering, or controls, with substantial time spent in simulation, SIL/HIL, or Co-Simulation for automotive or similar safety‑critical domains.
Proven experience as a System Architect, Software/System Engineer, or SIL/CoSim technical lead with responsibility for architecture across multiple programs or domains.
Strong understanding of body electronics / body controls (at least one of: vehicle access, cabin thermal, occupant positioning, lighting, visibility, occupant protection, vehicle state) at system and ECU level.
Deep hands‑on experience with SIL or Co-Simulation environments, including integration of virtual ECUs, plant models, and communication models for embedded controllers.
Proficiency with MATLAB / Simulink for plant and/or behavior model development and integration, and familiarity with FMU/FMI and SSP standards.
Strong skills in at least one system or software language used in CoSim tooling (e.g., C/C++, Python) and experience working with automated build / CI tools (e.g., Jenkins, Git, gcc/gdb, Eclipse or similar).
Solid knowledge of automotive communication technologies (CAN, LIN, automotive Ethernet) and experience modeling or configuring network behavior and RestBus in simulation.
Demonstrated ability to lead cross‑functional technical discussions, drive consensus, and make trade‑offs across performance, quality, and delivery.

Nice to have

Master’s degree in Engineering, Computer Science, or related field.
Prior Staff‑level or equivalent experience leading architecture for a complex embedded or simulation system (multiple ECUs, domains, and feature sets).
Experience designing or operating cSIL / continuous integration pipelines for embedded software, including quality gates, promotion strategies, and automated regression selection.
Hands‑on experience designing or leading variant and configuration management strategies for embedded software, CoSim, or test environments (parameter management, rules engines, asset BOMs).
Experience architecting RestBus and ECU behavioral models for body or multi‑domain CoSim, including diagnostics, fault injection, and error handling behavior.
Familiarity with AUTOSAR Layered Software Architecture and integration of AUTOSAR‑based ECUs into CoSim environments.
Experience with cloud‑hosted simulation / virtualization platforms and scaling CoSim execution on shared infrastructure.
Prior experience in the Virtualization & SIL Integration organization or similar virtual development teams is a plus.
Familiarity with performance‑oriented modeling (e.g., event‑driven, L4 abstractions, HPC).
