Key Responsibilities Develop end-to-end firmware test plans covering unit, integration, and system test stages, aligned with industry standards and product requirements.

Design detailed test cases for critical firmware functions, including boundary condition testing, fault injection (e.g., overvoltage, overcurrent), and long-term stability verification.

Develop and optimize test tools for firmware validation, such as Python-based automated scripts (using pytest framework), hardware interface tools (e.g., connecting to oscilloscopes, power analyzers), and log parsing tools for result analysis.

Execute high-quality manual tests with clear traceability, documenting test steps, data, and deviations in compliance with internal test protocols.

Collaborate with the firmware automation test team to analyze test results (e.g., failure patterns, coverage gaps), and track issues in Jira with timely reports to designers (including root-cause hypotheses).

Contribute to lab safety improvement initiatives, such as updating safety protocols for high-voltage test environments and conducting regular safety training for team members.

Continuously optimize test specs, methodologies, and procedures (e.g., reducing test cycle time by 10% through improved case prioritization) based on project feedback and industry best practices.

Participate in lab development, including commissioning of new test equipment (e.g., power supplies, communication analyzers) and calibration of existing tools to ensure measurement accuracy. 资格 Qualifications Bachelor’s degree or higher in Electrical Engineering, Automation Engineering, Computer Engineering, or related fields. 3+ years of hands-on firmware test experience in power electronics, control systems, or embedded systems, with a track record of validating firmware for power converters.

Proficiency in programming: Python for developing automated test scripts (e.g., integrating with CANoe/CANalyzer for communication testing). C/C++ to read firmware source code and design test cases targeting core logic (e.g., control algorithms).

Experience: with communication protocols, including: Designing test cases for CAN (2.0A/B), RS485 (Modbus RTU/TCP), Ethernet (TCP/IP), UART, and SPI.

Troubleshooting communication issues (e.g., packet loss, latency, protocol mismatches) using tools like Wireshark or CANalyzer.

Fluent in English (written and verbal) with the ability to draft English test reports and collaborate with international teams.

Proven ability to independently solve complex problems, such as: Diagnosing firmware crashes via log analysis and hardware signal debugging (e.g., using oscilloscopes to trace voltage spikes).

Resolving compatibility issues between test equipment and DUT in high-voltage environments.

Excellent teamwork and communication skills with an open and inclusive heart.

Ability to work under pressure in fast-paced project cycles, with strong attention to detail and a proactive approach to problem-solving.

Preferred:

Experience: in testing firmware for Power Electronic Converters (BESS, PV inverters, UPS, APF, EV Chargers). 时间表: 全职 请求编号: 009K0G
