What you'll do
- Lead technical engagement with hyperscale AI/cloud networking infrastructure, qualification, and sourcing teams to align product configuration, performance targets, telemetry needs, and sample plans. - Drive shipment readiness by coordinating demo hardware or EVB, reference firmware, interoperability coverage, tolerance testing, corner-condition calibration, and proactive system-level verification. - Own cross-functional issue resolution across firmware, system integration, CMIS interpretation, power and thermal limits, optical performance, telemetry, and manufacturing. - Coordinate with switch, NIC, and system vendors and internal product lines to eliminate interoperability blockers and optimize first-pass qualification success. - Provide executive updates, risk registers, and trade-off recommendations covering schedule, capacity, yield, BOM diversity, and customer commitments. - Support bring-up, qualification, and ramp through regular onsite and offsite reviews and hands-on technical support.
What you'll need
- B.S. or M.S. in Electrical Engineering, Physics, Optics, Computer Engineering, or a related field. - 7+ years of experience in technical marketing, customer engineering, systems engineering, or technical program management for optical transceivers, networking, or datacenter hardware. - Working knowledge of optical module qualification, firmware and system bring-up, CMIS, telemetry or DDM, power and thermal trade-offs, and switch or NIC interoperability. - Demonstrated ability to lead cross-functional teams across R&D, operations, quality, and external partners to resolve technical issues.
Nice to have
- Experience supporting 800G or 1.6T qualification or similar high-speed optical products with hyperscale customers.
