About the role:

The Staff System Architect CoSim Diagnostics NVM Network & Data/Release owns the endtoend architecture for:

• Diagnostic access NVM lifecycle 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 offboard tools (J2534equivalent) 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 HWIOSIM and related components ensuring realistic ECU lifecycle 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 endtoend 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.
  • Highlevel what changed / what was tested / under which configs overviews for stakeholders.
• Own userfacing 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.

Your Skills & Abilities (Qualifications)

• Bachelor of Science degree in Engineering Computer Science or a related technical field (or equivalent practical experience).
• 12 years of experience in software systems or platform engineering including significant work with virtualization SIL/CoSim or complex automotive ECU/tooling ecosystems.
• Strong understanding of automotive diagnostics including:
  • UDS (Unified Diagnostic Services)
  • RIDs/DIDs (Routine/Diagnostic IDs)
  • DoIP (Diagnostics over IP)
• Familiarity with NVM handling and ECU boot sequences
• Experience with network simulation or protocol stacks such as:
  • Ethernet and IPbased communication

• Strong background in data modeling ETL and reporting/BI ideally in an engineering or test context.
• Experience building and maintaining data integrations and dashboards/reports (e.g. Power BI or similar) for execution metrics coverage and health.
• Scripting skills (Python PowerShell or similar) for log processing and API integration.
• Familiarity with Jira CI/CD pipelines and simulation tools logging conventions (e.g. GMSIM dSPACE VEOS ETAS COSYM SOLE Robot Framework or similar).
• Excellent written communication for user documentation and release notes (Markdown Confluence Centrals etc.).
• Proven ability to design evolve and maintain behavioral and data models that are consumed by multiple teams and tools.
• Strong collaboration skills with Pipeline & Execution Plant Modeling CoSim Package/Variant Build & Toolchain Quality/Defect stakeholders and PMO.
