Job description

Sr Optical Alignment Engineer - Advanced Opto-Electronics

Location(s)

Molex possesses a rich heritage in the optical industry, delivering high-performance, field-proven optical solutions spanning components, modules, and fully integrated line cards. We provide cutting-edge wavelength management and amplifier technologies, supported by deep optical, mechanical, electrical, and software integration capabilities. These strengths enable Molex to serve the evolving needs of high-density, high-bandwidth, and flexible optical networks.

The Senior Optical Alignment Engineer will lead the strategy and implementation of optical coupling of photonic components to laser diodes for advanced packages (e.g., CPO, ELSFP). This role is responsible for alignment equipment and processes to achieve sub-micron stability for long-term reliability. The position requires close collaboration with R&D and product design teams, manufacturing, suppliers, and customers to ensure laser components meet stringent optical, mechanical, and Telcordia reliability requirements.

What You Will Do

• Provide technical leadership to design novel optical assemblies for coupling III-V laser diodes with high efficiency
• Design corresponding fiber mounts/assembly that includes components (e.g., fiber lens, lenses, PICs, SOA, VBG); Specify requirements for optical alignment equipment
• Develop processes for submicron alignment (x, y, z, f), solder or epoxy attach of components (e.g., laser diode, ceramic mounts)
• Partner with R&D and operation teams to ensure alignment equipment/processes are compatible with 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 associated with optical misalignment, working with internal teams, suppliers, and customers
• Work intimately with laser diode experts to create optimized optical designs for high coupling efficiency

Who You Are (Basic Qualifications)

• PhD in Optics, Photonics, Mechanical Engineering, or a closely related field
• 10+ years of industry R&D experience developing optoelectronic packages transferred to manufacturing environments
• Hands-on experience specifying the design of optical alignment equipment to achieve submicron tolerances
• Experience running Optics software package/s (e.g., Zemax) to optimize optical designs
• Knowledgeable of various optical components specifications (e.g., laser diodes, gratings, mirrors, lenses, PIC, SOA)
• Experience with stable attachment methods (e.g., glass frit, solder, epoxy)
• Experience with qualification methodologies (e.g., GR-468), reliability testing, and statistical analysis tools
• Experience with optical-packaging failure modes, with a demonstrated track record in failure mode analysis and resolution
• Experience with New Product Introduction (NPI) methodology: design, verification, qualification, release to manufacturing
• Experience effectively communicating with suppliers, customers, and cross-functional internal teams

For this role, we anticipate paying $180,000- $250,000 per year. This role is eligible for variable pay, issued as a monetary bonus or in another form.
