TL;DR · Optical Hardware Systems Test Engineer

The Optical Hardware Systems Test Engineer joins the ASIC Engineering team to validate and ensure the quality of next-generation networking platforms, including switches, routers, and data center systems. Working in a lab environment, you will lead the bring-up, validation, and characterization of Silicon One ASICs integrated with high-speed optical transceivers and emerging Co-Packaged Optics architectures. You will measure electro-optic channels across 112G/224G PAM4 SerDes links while evaluating eye quality, bit error rates, and link margins. To automate test workflows and control equipment like oscilloscopes, BERTs, and spectrum analyzers, you will develop scripts using Python or C/C++. The role involves solving complex signal integrity issues and performing stress testing across temperature and voltage corners to ensure stability for high-speed networking infrastructure. Key technical domains include Ethernet standards, PCIe, and advanced optical link budgets.

What you'll do

  • Lead the hands-on lab testing, validation, and bring-up of next-generation networking systems and high-speed silicon.
  • Validate 112G/224G PAM4 SerDes channels and advanced optical architectures like Co-Packaged Optics (CPO).
  • Measure and characterize high-speed electro-optic channels to evaluate eye quality, bit error rate, and link margins.
  • Develop and maintain Python or C/C++ scripts to automate test workflows and control lab equipment.
  • Perform system stress testing across temperature, voltage, and traffic corners to ensure link stability.
  • Debug and root-cause complex hardware, signal integrity, and optical link issues during prototype bring-up.
  • Collaborate with multi-functional teams to resolve technical issues from early silicon stages through production release.

What we're looking for

  • Bachelor's degree in Electrical Engineering, Photonics, Computer Engineering, or a related technical field.
  • 7+ years of industry experience with a Bachelor's, 4+ years with a Master's, or 1+ year with a PhD.
  • Hands-on experience in lab bring-up, system-level validation, and hardware testing of high-speed networking systems or electro-optic hardware.
  • Strong understanding of optical transceivers, link budgets, high-speed SerDes (56G/112G+ PAM4), and bit error rate testing.
  • Experience using standard lab instrumentation including VNAs, TDRs, sampling scopes, BERTs, and optical power meters.
  • Familiarity with Co-Packaged Optics (CPO), Near-Packaged Optics (NPO), or Linear Pluggable Optics (LPO) (preferred).
  • Expertise in high-speed interfaces, Ethernet standards (IEEE 802.3 400G/800G), PCIe, and optical transceiver management (preferred).
  • Proficiency in Python for test automation, instrument control, and data analysis (preferred).
