FPGA Engineer

Headquartered in Sunnyvale, California, Multibeam engages in the design, manufacture, and sales of multi-column electron-beam lithography (MEBL) systems that enable maskless production of integrated circuits (ICs) with on-chip security, rapid prototyping, heterogeneous chiplet integration, silicon photonics, and other emerging applications. Multibeam is led by Silicon Valley Engineering Hall of Famer, Dr. David K. Lam.

At the heart of Multibeam technology is an array of miniature e-beam columns that provide a maskless and high-throughput platform for writing nanoscale IC patterns seamlessly across full wafers. This solves key limitations widely recognized with e-beam lithography, transforming it from a mere R&D curiosity to an incredible fab tool for production. With MEBL systems, device makers can save on lithography costs, safeguard the IC supply chain, and revolutionize microelectronics manufacturing.

We believe the key to our success will be our people. Our best employees love what they do and bring unique backgrounds to our fast-paced, highly collaborative environment. We’re looking to expand our small team with like-minded individuals who want to grow with us.
