Optical Alignment Engineer - Submicron Precision

Molex; Fremont (CA); On-site; USD 180,000 - 250,000; Full time

Job summary

Molex seeks a Senior Optical Alignment Engineer to lead optical coupling of photonic components to laser diodes for advanced packages (e.g., CPO, ELSFP). The role owns alignment equipment and processes to achieve sub-micron stability for long-term reliability, and partners with R&D, design, manufacturing, suppliers, and customers to meet optical, mechanical, and Telcordia reliability requirements.

You will provide technical leadership to design optical assemblies for coupling III-V laser diodes

Qualifications

• PhD in Optics, Photonics, Mechanical Engineering, or a closely related field.

Responsibilities

• Provide technical leadership to design novel optical assemblies for coupling III-V laser diodes with high efficiency.
• Design fiber mounts/assemblies including fiber lens, lenses, PICs, SOA, VBG; specify requirements for optical alignment equipment.
• Develop processes for submicron alignment (x, y, z, f) and solder/epoxy attachment of components.
• Partner with R&D and operations to ensure manufacturable, high-yield assembly flows.
• Define and oversee pre-qualification testing to verify submicron optical stability for Telcordia qualification.
• Support failure analysis investigations and corrective actions related to optical misalignment.
• Work with laser diode experts to create optimized optical designs for high coupling efficiency.
