About the role The

Staff System Architect – CoSim Diagnostics, NVM, Network & Data/Release

owns the end‑to‑end architecture for:

Diagnostic access ,

NVM life‑cycle behavior , and

network behavior/corruption models

in

L3/L4 CoSim

and related pipelines, and

The

data model, traceability, dashboards, and documentation

connecting capabilities, packages, configs, tests, and results for the

Virtualization organization .

You will define how these behaviors and data flows are modeled, integrated into pipelines and exposed to test, quality, and program stakeholders, while ensuring alignment with security, safety, and release governance.

Key Responsibilities 1) CoSim & Virtual Platform Architecture (Diagnostics / NVM / Network)

Own

diagnostic access

in L3/L4 CoSim and related pipelines.

Define and implement

diagnostics integration , including:

Support for

off‑board tools

(J2534‑equivalent) into CoSim.

Robust handling of

RIDs/DIDs

and associated diagnostic data flows.

DoIP

flows in CoSim across virtual ECUs and networks.

Provide clear

diagnostic access methods and patterns

for test and integration teams.

Design and maintain

NVM simulation behavior

in CoSim:

Initialize from

provided NVM snapshots .

Save on sleep and

restore on boot .

Support behavior

per configuration/variant .

Own

sleep/wakeup and power mode behavior

in

HWIO_SIM

and related components, ensuring realistic ECU life‑cycle behavior.

Define and document

NVM strategies

for virtual environments and ensure consistent application across programs.

Develop and maintain

network behavior models

for virtual environments, with a focus on

Ethernet/SOME-IP

and

CAN .

Implement

corruption/injection capabilities

(e.g., frame drops, bit flips, latency/jitter, malformed frames) to support

TFRP and other tests .

Ensure network behavior models integrate cleanly with diagnostics and NVM behaviors for end‑to‑end test scenarios.

Define where

diagnostics, NVM, and network features

integrate into:

L3/L4 CoSim pipelines

SOLE/SystemBench

SILART

and related execution environments

Provide clear

APIs, configurations, and integration contracts

so pipelines can reliably configure and consume these capabilities.

Work closely with

Pipeline & Execution ,

Plant Modeling ,

CoSim Package/Variant , and

Build & Toolchain

teams to ensure seamless, reproducible behavior in CI/CD and execution flows.

2) Data / Release, Traceability & Documentation (SILART & Virtualization)

Define and maintain the traceability data model

connecting:

Capabilities → features → packages → variants/configs → test plans → runs → metrics .

Implement and maintain data integrations

to:

Ingest logs/results from

GMSIM ,

SOLE ,

Autobot/BDDbot , etc., into metrics stores (e.g.,

InSPIRE or equivalent ).

Build and support dashboards and reports

(e.g.,

Power BI

or similar) covering:

Execution metrics, coverage, and trends.

Package and variant health for CoSim/SILART.

Standardize release documentation , including:

Markdown

release notes for CoSim packages , wired into

SOLE/portals .

High‑level “ what changed / what was tested / under which configs ” overviews for stakeholders.

Own user‑facing documentation migration and structure

(e.g.,

Centrals/Confluence ), and ensure it remains aligned with actual tooling, flows, and pipelines.

3) HV/LV & Charging Domain

Bring or rapidly build strong

HV/LV and charging system context

so CoSim behaviors and data models reflect how diagnostics, NVM, and network behavior impact HV/LV and charging use cases (e.g., AC/DC charge sessions, power flows, isolation,



contactor behavior, DC/DC operation, safety interlocks).

Apply working knowledge of

Battery Management System (BMS)

behavior, including cell/pack monitoring, balancing, limits, and protections, to shape realistic CoSim behaviors and test scenarios.

Incorporate

state‑of‑charge (SoC) ,

state‑of‑health (SoH) , and related HV battery KPIs into CoSim models, test conditions, and reporting so that coverage reflects real HV system constraints and degradation.

Understand interactions between

HV energy storage ,

LV networks , and

onboard/offboard charging equipment , and how faults or limits propagate across those domains.

Consider relevant

V2X/V2G charging interactions

and communication where applicable, ensuring virtual environments can represent key interface behaviors and failure modes.

Work with

HV/LV and charging feature teams

to ensure CoSim environments support representative scenarios, edge cases, and fault conditions (e.g., failed charge attempts, derating, thermal limits, connector/cable issues, 12V support/limits).

Ensure traceability and reporting capture key

HV/LV and charging metrics and scenarios

so stakeholders can understand coverage, residual risk, and readiness for programs.
