• 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.

• Virtual Platform Architecture (Diagnostics / NVM / Network) Own diagnostic access in L3/L4 CoSim and related pipelines. Robust handling of RIDs/DIDs and associated diagnostic data flows. DoIP flows in CoSim across virtual ECUs and networks. Provide explicit diagnostic access methods and patterns for test and integration teams. Support behavior per configuration/variant. 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. 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.

High‑level “what changed / what was tested / under which configs” overviews for stakeholders. Centrals/Confluence), and ensure it remains aligned with actual tooling, flows, and pipelines.





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. Ensure traceability and reporting capture key HV/LV and charging metrics and scenarios so stakeholders can understand coverage, residual risk, and readiness for programs.
