You’ll work closely with various engineers, product managers, and key vendors to ensure seamless interoperability across Arista’s platforms

What You’ll Do

Arista Networks is seeking an Optics Engineer to join the Optics/Hardware group. The Arista Optics team manages copper and optical interconnection products across all Arista platforms, covering everything from 10G to 1.6T client optics and long-haul coherent optical solutions. The candidate will be actively involved in ODVT testing of optical transceivers within platform environments to ensure system interoperability. This role positions the individual as a subject matter expert, with responsibilities including optics specification development, testing, and analysis.

This is an exciting opportunity for a professional with industry and technical expertise in optics to contribute and lead in the upcoming transition to 1.6T full retimed, LRO, and LPO—the next generation of AI data center networking solutions.

• Lead Optical Design Verification Testing (ODVT) for PAM4-based 50G, 100G, 200G, 400G, 800G, and 1.6T optical transceivers.
• Perform ODVT measurements and characterization of 800G LPO, and 800G/1.6T optical transceivers.
• Write and maintain Python-based code to automate test flows, control lab instruments and log test results at scale.
• Set up and run optical/electrical tests using tools like BERTs, power meters, spectrum analyzers and oscilloscopes.
• Conduct benchmarking of emerging optical technologies to assess performance and compatibility.
• Develop and maintain manufacturing test infrastructure for optical transceiver products.
• Serve as the optics subject matter expert, providing support to internal teams and external customers.
• Create comprehensive test reports, documenting test procedures, equipment used, and results obtained.
