ABOUT THE ROLE
As a Senior / Staff Test Automation Engineer you will design, develop, and execute automated test frameworks for complex automotive Electronic Control Units (ECUs) and virtual ECUs (vECUs). This role bridges the gap between low-level firmware and high-level vehicle applications. You will own the end-to-end automation pipeline across Software-in-the-Loop (SIL) and Hardware-in-the-Loop (HIL) environments, which includes building custom HIL testing stations from scratch. Operating within a GNU/Linux ecosystem, you will investigate complex system requirements to develop robust, fail-safe test content for our next-generation Software-Defined Vehicle (SDV) platform.
Responsibilities
- Automation Framework Development: Design, build, and maintain scalable automated test frameworks and scripts for embedded automotive systems using Python and C/C++.
- HIL Bench Generation: Configure and build custom physical HIL test benches from the ground up, integrating real vehicle ECUs with simulated real-time environment models.
- Requirements Investigation: Analyze and interpret technical specifications to author comprehensive automated test suites, actively tracking down gaps in system requirements.
- Multi-Environment Execution: Execute automated test suites across SIL, MIL, and HIL setups.
- Analyze test captures, isolate low-level system failures, and generate detailed engineering reports.
- Protocol Verification: Validate automotive communication networks, network topologies, and diagnostic routing (e.g., CAN-FD, LIN, Automotive Ethernet, UDS, DoIP).
- CI/CD Integration: Integrate automated test loops directly into Git-driven CI/CD pipelines (such as GitLab CI or Jenkins) to support high-frequency regression farm execution.
- Cross-Functional Collaboration: Partner with Firmware, Systems Architecture, Quality, and TPM teams to define test specifications and maintain complete ASPICE-compliant requirement traceability.
QUALIFICATIONS
- Education: Bachelor’s or Master’s degree in Electrical Engineering, Computer Engineering, Computer Science, or a related field.
- Experience: 5+ years (Senior) or 8+ years (Staff) of hands-on experience in test automation for high-integrity embedded systems.
- Programming Mastery: Expert-level proficiency in Python and Bash scripting, alongside a practical reading knowledge of C for code-level debugging.
- Automation Toolchains: Direct experience architecting or heavily extending modern pythonic test frameworks (such as Pytest or OpenHTF).
- Containers: Experience with Docker
PREFERRED QUALIFICATIONS
- Linux Expertise: Advanced user-level comfort navigating, configuring, and scripting within GNU/Linux environments.
- Version Control: Advance user-level with Git and modern branch management strategies.
- Network & Diagnostic Diagnostics: Deep technical understanding of automotive network protocols (CAN, LIN, Ethernet).
