Responsibilities

• Develop automated testing for power supply electrical performance and protection.
• Develop production tests solutions for power supplies, AC/DC and DC/DC converter products incorporating digital control, microcontrollers and communications interfaces.
• Support debugging of hardware, firmware, communication, and test-system issues.
• Work with PCB, mechanical, and external suppliers to develop robust and reliable test fixtures.
• Design and develop production test jigs, fixtures, interface boards, cable harnesses and test adapters as per electrical and mechanical requirements.
• Ensure electrical and operator safety, ESD protection, grounding, shielding, contacts resistance and connector durability.
• Provide technical leadership in resolving production test failures and manufacturing issues.
• Perform failure analysis and root‑cause investigation to identify product, test‑system, fixture, software/test‑program, process, or operator‑related issues, and implement corrective actions.
• Analyse test data, yield, false failures, and test escapes to improve quality.
• Develop test specifications, methods, limits, procedures, test coverage and training materials.
• Define appropriate test limits based on product specifications, measurement capability, process variation and statistical data.
• Optimize test coverage, test time, cost and reliability.
• Work closely with design engineers and manufacturing team to define Design for Testability (DFT) requirements and production test strategies for new products.
• Qualify and release ATE systems, fixtures, and test software.
• Support production ramp‑up and transfer test systems to manufacturing sites.
• Act as the technical owner for assigned production test systems.
• Drive continuous improvements in automation, test coverage, test time, reliability, and manufacturing efficiency.
• Evaluate new test technologies and work with external suppliers.
• Develop ATE systems and automated production test programs.
• Integrate instruments such as AC sources, electronic loads, DMMs, oscilloscopes, and DAQ systems.
• Develop test software using LabVIEW, Python, C/C++, and instrument communication protocols using SCPI, Ethernet, USB, RS-232/485, CAN, I²C, SPI, UART, etc.
