With more than 30 years of combined experience in the field of optoelectronics our OSI Optoelectronics (OSIO) division is a diversified manufacturer of standard and custom photodiodes and optical sensors for use in aerospace, defense, commercial and medical applications. We are one of the largest global manufacturers of optoelectronic devices, delivering engineering design support and manufacturing capabilities that include products for use in the defense, aerospace, medical, and industrial markets, among others. We utilize our world‑class manufacturing facilities in the U.S., India and Malaysia to continue to put forth excellent engineering solutions aligned with efficient manufacturing to meet high‑volume production requirements. OSIO Optoelectronics is seeking a Test Engineer to join the team. This individual will be responsible for developing and implementing wafer probe and final test solutions for bipolar transistor, MOSFET and diode semiconductors. They will design, develop and troubleshoot test fixtures to execute MIL-STD-750 and MIL-STD-883 Test Methods. In addition, they will perform analysis of lot data to determine Delta parameters and Three Sigma calculations. Responsibilities Performs DC and AC bench measurements of semiconductors using various equipment like Lorlin or TESEC semiconductor testers, Spectrum analyzer, Oscilloscope and Pulse generator. Documentation of test methodology, operating instructions, qualification protocols, and development of test procedure documents to support standardized testing and training. Perform data analysis from lot measurements to evaluate trends, establish baseline performance, calculate delta parameters and three sigma limits, and identify abnormal variation affecting yield, quality, or reliability. Design and develop test hardware (e.g., interface boards, sockets, fixtures) and software for DC and AC measurements (e.g., switching time, hfe, leakage). Perform and debug test programs, tester hardware, and bench setups for accurate measurements. Selection and qualification of vendors for parts and materials to be used in test hardware. Work closely with Wafer Fab, Assembly, and Test teams to find solutions to production issues including identifying root causes and implementing corrective actions. Support failure analysis and investigation of failed parts and materials. Uphold the company’s core values of Integrity, Innovation, Accountability, and Teamwork. Demonstrate behavior consistent with the company’s Code of Ethics and Conduct. It is the responsibility of every employee to report to their manager or a member of senior management any quality problems or defects in order for corrective action to be implemented and to avoid recurrence of the problem.
