Optical Design Sr. Engineer
Confirmed on the employer's own hiring board on Oct 22, 2026. First seen by Alion on Oct 13, 2026.
About our group:
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.
About the role - you will:
- 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
About you:
- 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
Your experience includes:
- 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 (i.e. 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.
You might also have:
- Experience in failure analysis, data analysis, wafer processing techniques, image analysis, and six sigma tools (e.g. JMP, Python) are a plus
