About the Job

Requirements

  • A PhD in Photonics, Optics, Physics, Electrical Engineering, Applied Physics, or a closely related field is required.
  • At least 10 years of experience in photonic device or system development is required.
  • Deep technical expertise in photonic device physics, optical systems, and experimental development is required.
  • Demonstrated leadership of complex, multidisciplinary research and development programs from concept through prototype validation is required.
  • A strong understanding of photonic device design, fabrication, characterization, packaging, and system integration is required.
  • The candidate must be able to make sound technical decisions with incomplete data and resolve difficult first-principles engineering problems.
  • The candidate must have strong written and verbal communication skills, including the ability to influence technical direction across organizational boundaries.
  • A track record of mentoring technical contributors and building alignment among diverse engineering teams is required.

Responsibilities

  • Provide technical leadership for research and development of new photonic devices and systems for data storage and communications.
  • Define technology roadmaps, device architectures, performance targets, and development plans aligned with long-term business and research objectives.
  • Lead concept generation, feasibility assessment, modeling, design, fabrication, characterization, and prototype demonstration activities.
  • Guide technical tradeoff studies across optical performance, electrical drive, thermal behavior, reliability, manufacturability, packaging, and system integration.
  • Collaborate with device, process, test, packaging, electronics, firmware, and system teams to resolve complex cross-disciplinary challenges.
  • Establish experimental strategies and interpret device- and system-level data to accelerate learning and improve technical decisions.
  • Identify external technology trends, research opportunities, intellectual-property opportunities, and strategic partnerships.
  • Mentor engineers and scientists, drive rigorous technical reviews, and raise the organization’s photonics capability.
  • Communicate technical strategy, risks, progress, and recommendations clearly to engineering and business leadership.

Desired Qualifications

  • Experience developing photonic technologies for data storage, optical communications, or adjacent high-volume applications.
  • Expertise in semiconductor lasers, modulators, detectors, integrated photonics, micro-optics, or optical interconnects.
  • Experience bridging device-level innovation with system architecture and product requirements.
  • A strong record of patents, publications, invited presentations, or recognized technical leadership in photonics.
  • Experience working with external research institutions, fabrication partners, suppliers, or strategic technology collaborators.
  • Demonstrated ability to create new technology directions and translate them into executable development programs.

About the Company

Western Digital

Makes hard drives for cloud and AI data centers

Western Digital, which goes by WD, designs and makes hard disk drives, mostly the high-capacity models that cloud and AI data centers use to store huge amounts of data cheaply. In 2013, its HGST unit shipped the first helium-filled hard drives, which fit more disks into each drive and use less power. Its drives store data on stacks of spinning magnetic disks, and the lineup runs from Ultrastar data center drives to WD Red and WD Purple drives for home servers and security cameras. WD makes its money selling these drives to cloud companies, PC makers, and retail shoppers. Western Digital was founded in 1970 and is based in San Jose, California, and in 2025 it spun off its flash memory business as Sandisk.
