The Opportunity:

Adecco is partnering with a global leading photonics company in searching for a Senior Optical Transceiver R&D Engineer to join their growing R&D team. This position will own the design, characterization, and qualification of advanced optical transceiver reference designs. You will work across firmware, DSP, optics, and hardware to ensure our QSFP/OSFP-based transceivers meet performance and interoperability requirements.


The Job:

• 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

The Talent:

• Bachelor's or Master's degree in Electrical Engineering, Physics, or a related field
• 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
• 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

Next Steps:

• Prepare your updated resume (please include your current salary package with a full breakdown such as base, incentives, annual wage supplement, etc.) and expected package.
• Apply through this application or send your resume to ••••@adecco.com in MS Word Copy. We'd love to hear from you!
