Job Description

The Staff Test Engineering will be responsible for the entire test strategy and execution for a portfolio of Battery Management System (BMS) products. Oversee the development of test programs and automated test equipment (ATE) for characterization, qualification, and high-volume production of integrated circuits (ICs) used in lithium-ion battery packs. This role requires technical depth in mixed-signal and SOC IC testing and strong leadership to drive design for test, continuous improvement, product quality, and time-to-market.

Key responsibilities

Work in a team of test engineers fostering a culture of ownership, innovation, and technical excellence.
Work with Design team in defining DFT (Design for Test).
Review and define manufacturability flow and achieve best in class cost.
Provide technical guidance and support to junior engineers, ensuring skill development and adherence to best practices.

Test strategy and execution

Define and implement comprehensive test strategies for new BMS IC products, covering all phases from new product introduction (NPI) to high-volume manufacturing. release
Oversee the design, development, and debugging of automated test programs and hardware interfaces for ATE platforms.
Ensure that test coverage is robust and sufficient to guarantee the performance, reliability, and safety of product, including key functions like voltage/current monitoring, state-of-charge calculation, and cell balancing.
Analyze test data to monitor product yield, identify trends, and drive root-cause analysis for failures in collaboration with design, process, and manufacturing teams.

Cross-functional collaboration

Work closely with design, applications, and validation engineering teams to provide Design-for-Test (DFT) feedback and ensure a smooth transition from design to production.
Interface with foundry and outsourced semiconductor assembly and test (OSAT) partners to manage test solutions and address issues for high-volume manufacturing.
Collaborate with the quality and reliability teams to ensure all testing processes comply with industry standards (e.g., ISO 26262, IEC, AEC-Q100) and regulatory requirements.

Process improvement

Drive continuous improvement initiatives to enhance test efficiency, optimize cycle time, and costs.
Evaluate and deploy new test equipment, technologies, and methodologies to improve test capabilities for new and product requirement.
Develop and maintain comprehensive test documentation, including plans, procedures, and reports.

Qualifications

Education: Bachelor's or Master's degree in Electrical Engineering.
Experience:
- 10+ years of experience in semiconductor test engineering, with a focus on mixed-signal and analog ICs.
- 3+ years of experience in a technical leadership or management role.
- Proven experience with test solutions for high-performance analog, SOC and mixed-signal products.
- Experience with battery technology and Battery Management Systems is highly preferred.
Skills:
- Deep understanding of semiconductor device physics and analog/digital circuit design.
- Proficiency in test automation programming languages such as Python, VBA, C/C++, or MATLAB.
- Strong knowledge of industry-standard Automated Test Equipment (ATE), such as Chroma, Advantest, Teradyne, or Cohu.
- Experience with statistic and data analysis tools.
- Knowledge of standard communication protocols used in BMS (e.g., I2C, SPI, SMBus, CAN).
Attributes:
- Excellent leadership, communication, and interpersonal skills.
- Exceptional problem-solving and analytical abilities.
- Ability to balance technical details with business requirement.
