Senior Optical Process and Manufacturing Engineer

Arista Networks is seeking a skilled and driven Senior Optical Process and Manufacturing Engineer to support the transition of next-generation optical interconnects — including 800G and 1.6T transceiver modules — from R&D into high-volume production. In this role, you will work closely with hardware architects, design engineers, contract manufacturers (CMs), and component vendors to develop robust, scalable, and cost-effective assembly and test processes. Your work will be essential in ensuring performance, yield, and manufacturability targets are consistently met or exceeded for Arista’s industry-leading optical transceivers.

You’ll be part of a highly cross-functional team, helping define manufacturing flows, debug issues, manage process qualifications, and support production ramp-up for advanced optical modules and engines, including chiplet-based and co-packaged designs.

• Develop and qualify assembly and test processes for optical interconnects, high-density optical engines, and transceiver modules, including fiber attach, active/passive alignment, and high-precision optical integration.
• Drive process development for wire-bonding and flip-chip assemblies used in optical engines and chiplet packaging.
• Collaborate with design teams on DFX (Design for Manufacturing, Test, and Yield) to ensure smooth product transition into mass production.
• Work closely with CMs and vendors to define process controls, tooling, fixtures, and automated test solutions.
• Drive yield improvement, root cause analysis, and continuous process optimization from pilot to production builds.
• Support optical epoxy dispensing, underfill, MPO connector assembly, and other complex packaging processes.
• Create and manage process documentation such as PFMEA, control plans, work instructions, and test specifications.
• Analyze production and reliability data to identify trends, improve process performance, and mitigate risks.
• Participate in supplier and CM audits, qualifications, and equipment/process validation.
• Collaborate with supply chain and quality teams on material selection, incoming inspection, and vendor management.
• Work with design, test, and reliability teams to ensure module quality, cost, and performance meet Arista’s standards.
