Nice-to-have
Acceler8Talent is proud to partner with a well-funded, VC-backed AI/networking hardware startup in the SF Bay area that’s redefining infrastructure for the world’s largest hyperscalers. Operating under a Joint Development Model (JDM), this company co-develops highly customized networking hardware, optics, and software solutions tailored to the evolving needs of large-scale AI workloads in data centers.
With over $110M in funding and rapid expansion underway, they're now looking to hire a Senior Optical Test Engineer to lead the qualification, validation, and system-level testing of high-speed optical modules (e.g., 400G, 800G, 1.6T) used in advanced datacenter and AI networking environments.
Responsibilities
Lab Bring-Up and Test Automation: Setup and maintain test environments using BERTs, power meters, oscilloscopes, and traffic generators. Automate workflows using Python.
Optical Module Qualification: Test and characterize transceivers across temperature, voltage, and traffic conditions to ensure performance and compliance.
System-Level Validation: Validate module performance in switch ASIC systems and AI networking setups. Capture metrics like BER, power consumption, thermal stability, and link reliability under stress.
Debug and Analysis: Troubleshoot performance issues such as signal integrity degradation, module misbehavior, or unexpected power/thermal behavior. Collaborate with cross-functional teams for root-cause analysis.
Requirements
B. S. or M.S. in Electrical Engineering, Optical Engineering, Physics, or a related field
