Job description

The engineer will develop and execute host test procedures, characterize and qualify host designs, and help ensure product compliance with internal specifications and industry
standards. The work spans multiple Cisco hardware platforms and optical interfaces from 1 Gbps to 224 Gbps per lane, including DAC, multimode, single-mode, CPO, LPO, and LRO
solutions.
Responsibilities

  • Review engineering specifications and develop test strategies for new products.
  • Integrate test equipment and build test systems and environments.
  • Use automation to implement test strategies and improve efficiency.
  • Test products against internal specifications and industry standards.
  • Mitigate issues, drive them to closure, and support root cause analysis for field issues and customer escalations.
  • Document test plans, procedures, and reports.
  • Collaborate with system designers, signal integrity, software and diagnostics, customer escalation teams, and external vendors.

Minimum qualifications

  • Bachelor’s degree in electrical or computer engineering with at least 2 years of relevant experience, or a master’s degree in either field.
  • Experience with electrical or optical test and measurement equipment, such as oscilloscopes with CDR, network or spectrum analyzers, noise generators, or traffic generators.
  • Experience with high-speed SERDES or signal integrity.

Preferred qualifications

  • Test automation experience with Python, C/C++, or MATLAB.
  • Knowledge of optical transceiver theory, functional blocks, form factors (SFP, QSFP, OSFP, QSFP-DD), and optical signal measurement.
  • Experience with troubleshooting, diagnostics, instrument control, and automated measurement scripting.
  • Experience developing physical-layer evaluation methods for hardware and optics based on product requirements.
  • Familiarity with hardware subsystems, including CPUs or microcontrollers, LVDS, clocking, power, schematics, and board layout.
  • Familiarity with IEEE 802.3, OIF/CEI, MSA, or SFF-8431 standards.
  • Experience with AI and agent frameworks such as Pydantic/PydanticAI, LangGraph, LangChain, OpenAI Agents SDK, AutoGen, CrewAI, MCP, tool calling, or LLM orchestration.
  • Experience with instrument interfaces and automation, such as SCPI, VISA/PyVISA, NI-VISA, LabVIEW, IVI drivers, serial/RS-232, TCP/IP, or automated test equipment.
  • Python experience, including asyncio, multithreading, multiprocessing, PySide6, PyQt, or Qt.
