• As a MACsec Testing and Debugging Engineer, you will be responsible for validating and troubleshooting the MACsec implementation on our industrial products. You will design and execute test plans and perform in-depth debugging all reported issues. This role requires collaboration with cross-functional teams, including hardware and software engineers, to identify and resolve complex issues.

Key responsibilities

• Test plan development: Review current Test plan and create/maintain additional test plans and test cases for MACsec functionality, including performance, security, and interoperability.
• Test environment setup: Configure test setups using HIL and test benches to simulate product use case.
• Functional testing: Validate proper MACsec functionality, including encryption and decryption, frame integrity checks (ICV), and secure key exchanges using the MKA protocol.
• Performance and stress testing: Benchmark MACsec performance under various conditions, such as high-speed traffic (e.g., 100G, 800GE), mixed traffic types (e.g., MACsec and non-MACsec), and different frame sizes.
• Security vulnerability testing: Develop and execute negative test cases to validate MACsec robustness against attacks, malformed packets, and other error conditions.
• Debugging and root cause analysis: Utilize network analyzers (like Wireshark), traffic generators, and internal logging to debug and analyze failures in the MACsec protocol.
• Issue reporting and tracking: Identify, report, and track software and hardware defects in a bug-tracking system, providing detailed and reproducible steps.
• Automation: Create and maintain automated test scripts to improve testing efficiency and coverage.
• Documentation: Document test results, debug findings, and best practices for future reference.

Qualifications

• Experience: 5+ years of experience in industrial connectivity devices development and testing for cybersecurity , with specific experience in MACsec (IEEE 802.1AE) and MKA (IEEE 802.1X).
• Technical skills:
• OS: Experience with Linux-based embedded systems.
• Programming: Experience in C & C++ development, Strong scripting skills (e.g., Python) for test automation
• Problem-solving: Excellent analytical and debugging skills with a systematic approach to root cause analysis.
• Communication: Strong written and verbal communication skills to effectively collaborate with engineers and stakeholders.

Education:

• Bachelor's degree in computer science, Electrical Engineering, or a related field.
