Job

Our technology development group designs Heat Assisted Magnetic Recording (HAMR) heads for future products. We design integrated optics that delivers light from a laser to a Near-Field Transducer (NFT), and design the plasmonic NFT that focuses the laser light down to a spot size 10’s of nanometers in diameter (10x smaller than the diffraction limit). We also design the magnetic circuit that applies a >2 Tesla, GHz magnetic field within nanometers of the NFT’s optical spot.

This “leading-edge photonic and magnetic integration” designed by our group won the 2026 SPIE Prism Award in the Optical Materials and Components category.

• Help identify and invent concepts that will improve HAMR recording head performance
• Optimize NFT designs to improve performance and reliability
• Work closely with other designers and the wafer process team to build your ideas into real devices, which will require evaluating design/process tradeoffs and optimizations
• Work with other designers and the test team to characterize the new devices, which will require utilizing standard tests and developing novel test methodologies
• Use analytical tools, numerical models and experimental data to improve HAMR understanding and then communicate this new understanding to other teams, such as the product, wafer processing and test teams

• Collaborate effectively with cross-functional teams
• Work independently with minimal supervision
• Strong problem solver with an innovative mindset
• Demonstrate agility and adaptability in a rapidly evolving industry

• Experience with near-field optics, plasmonic, waveguide optics and device physics
• Expertise in integrated optical component design and analysis
• Experience with optical modeling design tools (e.g. COMSOL, Lumerical, RSoft, FDTD)
• Bachelor’s degree in engineering related field (e.g. Electrical, Mechanical, Chemical, Computer Engineering, Materials, Physics, or Information Technology) and 5+ years of experience or master’s degree in the same and 3+ years’ experience or PhD and 0+ years’ experience or equivalent experience and education.

• Experience in failure analysis, data analysis, wafer processing techniques, image analysis, and six sigma tools (e.g. JMP, Python) are a plus
