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

Role Overview

• Own the end‑to‑end architecture for Diagnostic access, NVM life‑cycle behavior, and network behavior/corruption models in L3/L4 CoSim and related pipelines.
• 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.
• Define and implement diagnostics integration, including: Support for off‑board tools (J2534‑equivalent) into CoSim.
• Design and maintain NVM simulation behavior in CoSim.
• 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 to support TFRP and other tests.
• Ensure network behavior models integrate cleanly with diagnostics and NVM behaviors for end‑to‑end test scenarios.
• 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.

Requirements

• 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 IP-based communication Simulated Ethernet or similar virtual network models.
• Hands-on experience with modeling/scripting to implement behaviors and automation (e.g., Simulink, Python, Robot Framework, or equivalent).
• 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.
• Ability to influence architecture and standards across organizational boundaries and sites.
