Jobtailor; Fremont (CA); On-site; USD 140,000 - 210,000; Full time

Job summary

Jobtailor is seeking a hardware engineer to standardize XDVT test coverage for 800G, 1.6T, and future transceivers. You will define coverage, streamline submission and data reporting, and coordinate XDVT activities across R&D sites.

You will work with switch and DSP vendors for co-debugging on challenging link flap issues, and help develop tuning algorithms for Switch-based setups. Travel to other sites may be required.

Qualifications

• BS EE with 9+ years or MS EE with 7+ years required.
• Proficient in Python programming.
• Experience in optical transceiver characterization.
• Familiar with Switch OS such as Sonic by MSFT, Cumulus by Nvidia and VEOS by Arista.
• Strong data analysis using SQL, JMP, MS Excel.
• Hands-on experience with optical test instruments (DCA, OSA, BERT).

Responsibilities

• Standardize XDVT test coverage for 800G/1.6T and future transceivers.
• Coordinate global XDVT activities with R&D sites.
• Assist design/QA teams with evaluation and debugging on switches.
• Interface with switch and DSP vendors for co-debugging on link flap issues.
• Co-develop tuning algorithms for Switch-based setups (LPO/LRO).
• Establish switch-based knowledge base and best practices.

Job description

Responsibilities

• Assist in the standardization and implementation of Switch‑based DVT (XDVT) test coverage for all new 800G, 1.6T and future 3.2T optical transceiver products. This includes continuously defining the new test coverage and streamlining the XDVT submission, verification and data reporting process.
• Coordinate on the global XDVT activities, and assist/advise on the XDVT failure analysis working closely with different design teams from all R/D sites.
• Assist module design team/QA team for urgent optical transceiver evaluation, optimization and debugging on switches.
• Be able to directly interface with Switch‑vendor and DSP vendor for co‑debugging on the very challenging link flap issues as part of joint efforts by cross‑functional teams.
• Co‑develop the special module tuning/optimization algorithm on Switch‑based setup for LPO and LRO products by collaborating with design teams, customers and/or switch vendors.
• Establish the Switch‑based knowledge base in three areas: Switch study/characterization as part of design guidance; Switch‑based product evaluation/optimization methodologies and lessons learned; Issues found on customer switch systems: Lesson learned, corrective actions and suggested design improvement.
• Work closely with Switch test engineer to bring up the new types of switches and have regular interaction with various switch vendors for co‑debugging and feature request.
• Need light travel to other sites to facilitate the implementation of the Switch‑based test platform and standardize the XDVT execution.

Requirements

• B.S. EE degree with 9‑year experience or M.S. EE degree with 7‑year experience required.
• Strong programming skills with Python are preferred.
• Familiar with optical transceiver product characterization, validation and failure analysis in Switch‑based system.
• Familiar with or capable of quick learning on Switch OS, such as Sonic by MSFT, Cumulus by Nvidia and VEOS by Arista.
• Experience in link performance optimization on Switch rack system in data center is a Plus.
• Basic knowledge in IEEE standard in terms of test specs and test methodologies.
• Solid knowledge in PCBA, RF and Fiber optics is highly preferred.
• Strong laboratory optical and electrical measurement skills required.
• Hands‑on experience in optical test instruments, such as DCA, OSA, BERT, etc., is a Must.
• Strong data analysis skills with SQL, JMP, MS Excel.
• Strong skills in communication, presentation and documentation.
