At Western Digital, our vision is to power global innovation and push the boundaries of technology to make what you thought was once impossible, possible.
For decades, we’ve been doing just that—our technology helped people put a man on the moon and capture the first-ever picture of a black hole.
From enabling systems to make cities safer and more connected, to powering the data centers behind many of the world’s biggest companies and hyperscale cloud providers, to meeting the massive and ever-growing data storage needs of the AI era, Western Digital is fueling a brighter, smarter future.
Together, we can build the future of data storage.
The Senior Development Engineer will drive the design and optimization of epitaxial stacks for VCSEL and related photonic device structures. The role focuses on translating device‑level requirements into robust epitaxial designs, using advanced semiconductor physics and numerical simulations to guide development and optimize performance, yield, and reliability. This position is ideal for someone with a strong academic and/or R&D background in semiconductor physics and photonic devices who wants to work at the interface of epitaxy, device design, and product development.
optical cavity / mode simulations, carrier transport, thermal behavior) to support architecture decisions.
Interpret measurement and reliability data. Analyze and correlate simulation, epitaxial, and device performance data to identify root causes and optimization paths.
Collaborate in a multi‑disciplinary, international R&D environment, coordinating with colleagues across different locations and time zones (with substantial overlap to EU working hours).
Mentor junior engineers and students in topics such as semiconductor device physics, simulation methodology, and data analysis.
PhD in Materials Science, Physics, Electrical Engineering, or a closely related field.
Solid track record in semiconductor devices, preferably in photonic devices such as lasers, LEDs, or VCSELs.
Deep understanding of semiconductor physics, including:
Strong ability to interpret experimental data (e.g., I‑V, L‑I, spectral, far‑field, lifetime/reliability data) and connect results to physical mechanisms and design choices.
Fluent English (spoken and written), with the ability to write clear technical documentation and present complex topics to a mixed audience.
