Fiber Optics Test Development and Assembly Support Engineer - Yishun

The ideal candidate is a strong team player with hands-on experience in optical and electronic test systems, test automation (Python), communication protocols (I2C), and working knowledge of high-speed PCB design and FPGA-based systems.

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.
