Senior Optical Test Engineer - Optical Transceivers
Acceler8 Talent 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. They are seeking a Senior Optical Test Engineer to lead the qualification, validation, and system-level testing of high-speed optical modules 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
Qualification
Required
B.S. or M.S. in Electrical Engineering, Optical Engineering, Physics, or a related field
5+ years of experience testing optical modules or electrical/optical systems
Hands-on experience in high-speed optical transmission testing, including fiber links, and state of the art test equipment: BERT, oscilloscope, DCA, power meters, OSA, thermal chambers
Strong Python scripting skills for lab automation and programming languages for data collection and analysis
Familiarity with CMIS, MDIO, or I²C interfaces
Understanding of high-speed protocols such as Ethernet, PCIe, or SerDes
Industry experience working with 400G/800G/1.6T pluggable modules (QSFP-DD, OSFP)
Knowledge of IEEE 802.3 Ethernet, MSA or OIF standards including CMIS
Experience validating hardware in datacenter or AI cluster environments
Familiarity with environmental and reliability testing (temperature cycling, HTOL, etc.)
