Key Responsibilities
- Define and execute test plans for optical transceivers (IMDD and/or coherent)
- Characterize transceiver performance for 1.6T modules - BER, eye diagrams, SNR, OSNR, TDECQ, OER, OMA, receiver sensitivity, latency, and more
- Validate TFLN modulator-based transceivers across electrical, optical, and thermal domains
- Bring up and debug QSFP/OSFP transceiver modules
- Collaborate with firmware and DSP teams to tune system performance
- Support compliance testing (IEEE, OIF, CMIS)
- Analyze failures, drive root-cause resolution, and recommend design improvements
Required Qualifications
- Bachelor's or Master's degree in Electrical Engineering, Physics, or a related field
- 5 to 12+ years of relevant experience in high-speed optical transceiver testing and/or design ( 400 Gbps)
- Experience with Datacom and/or Telecom transceivers
- Hands-on experience with QSFP and OSFP form factors
- Solid understanding of PAM4, TDECQ, BER, OSNR, jitter, eye diagrams, and receiver sensitivity
- Proficiency with lab equipment - oscilloscope, DCA, BERT, OSA, VNA, etc.
- Strong debugging skills and a methodical approach to troubleshooting
- Clear communicator, able to articulate issues and solutions across teams
Preferred Qualifications
- Experience with TFLN, silicon photonics, or other advanced modulator technologies
- Familiarity with PAM4, coherent detection, and DSP-based systems
- Experience with thermal and reliability testing
- Experience building semi-automated test systems
- Familiarity with the OSFP/QSFP MSA specifications
Key Skills
