We are seeking a Principal Systems Engineer to lead the development of next-generation optical transceivers for hyperscale data center and AI networking applications. This individual will play a critical role in driving system-level innovation, translating customer and industry requirements into product specifications, and leading cross-functional teams through product development, qualification, and deployment.
The ideal candidate possesses expertise in optical communications, coherent or direct-detect optical systems, DSP architectures, electrical and optical interfaces, and emerging data center networking standards. This role requires both technical leadership and solid collaboration across silicon, optics, packaging, firmware, manufacturing, and customer-facing teams.
As a Principal Systems Engineer, you will define the architecture and technical direction of next-generation optical interconnect solutions, enabling the massive bandwidth demands of AI clusters and hyperscale data centers. Your work will directly influence product strategy, industry standards, and the future of high-speed optical networking.
What will you do? Define system requirements and product architecture for next-generation optical transceivers.
Develop transceiver specifications, link budgets, performance targets, and system trade-off analyses.
Lead architecture decisions involving optical engines, DSPs, laser technologies, packaging, thermal management, and host electrical interfaces.
Evaluate various modulation schemes, lane rates, and optical interconnect architectures to optimize performance, power, cost,



and manufacturability.
Serve as the technical lead transceiver product development, influencing technology roadmaps and strategic investments.
Mentor engineers across systems, optics, hardware, firmware, and validation disciplines.
Drive design reviews and resolve complex cross-functional technical issues.
Represent the company in customer engagements and industry technical discussions.
Optical and Electrical System Analysis, including Define and analyze optical link performance, Link budgets/ Signal-to-noise ratio (SNR)/ BER/FEC performance/ Power consumption, and Reliability margins
Perform system-level modeling and simulation of optical and electrical channels.
Analyze and optimize high-speed interfaces operating at 200G/lane and beyond.
Work closely with DSP and ASIC teams to define equalization, FEC, and signal integrity requirements.
Product Development & Validation, including Collaborate with optics, ASIC, packaging, firmware, and operations teams from concept through production release.
Define validation methodologies and interoperability test plans.
Drive root-cause analysis and corrective actions for system-level performance issues.
Support customer qualifications,



field deployments, and technical escalations.
