Key Responsibilities: Develop and maintain semi-automated test systems for optical and electronic components for R&D. Support the assembly and troubleshooting of fiber optic modules, including root cause analysis of failures during prototyping and production. Interface with and program I2C-based devices for configuration and diagnostics. Operate and interpret data from test instruments including power meters, optical spectrum analyzers, oscilloscopes, optical scope, BERTs, and high-speed signal analyzers. Assist in the design and validation of high-speed PCBs, including signal integrity review and testing. Work with FPGA engineers to test and validate firmware functionality during development and integration phases. Collaborate closely with R&D, NPI, and manufacturing teams to ensure smooth transfer of new designs into production. Create and maintain documentation including test procedures, work instructions, and technical reports. Support continuous improvement initiatives in both product design and test processes. Required Qualifications: Bachelor's or Master's degree in Electrical Engineering, Optical Engineering, or a related field OR Diploma in electronics with > 5 years hands on experience 3-5 years of experience in test engineering, preferably in fiber optics or high-speed electronics. Proficient in Python for test automation and data processing. Strong understanding of I2C communication, including debugging and register mapping. Hands-on experience with optical and electronic test equipment. Exposure to high-speed PCB design (signal integrity, layout constraints, impedance control). Basic familiarity with FPGA hardware and firmware, including understanding of interfaces and debug processes. Experience supporting manufacturing or assembly processes in a technical role. Excellent problem solving and analytical skills Very strong in cross-functional collaboration and communication skills Preferred Technical Skills: Experience with high-speed optical transceivers (QSFP/SFP), PAM4, or embedded optics. Familiarity with test data analysis tools (e.g., MATLAB, Excel, or custom dashboards). Knowledge of communication protocols beyond I2C (SPI, UART, MDIO). Exposure to PCB design tools (Altium, Cadence) and simulation software. Experience with version control and test data management systems. Exposure to high-speed PCB design (signal integrity, layout constraints, impedance control). Basic familiarity with FPGA hardware and firmware, including understanding of interfaces and debug processes.
