About The Position

We are seeking a highly skilled System Application Engineer (Hardware) to support next-generation AI networking platforms and high-speed optical interconnects. In this role, you will work closely with customers deploying 800G and 1.6T optical transceivers on 51.2T-class and emerging switch architectures, with a strong emphasis on hardware bring-up, lab validation, interoperability testing, and system-level debug. The ideal candidate brings deep experience with optical module operation, DSP tuning, board- and system-level validation, and high-speed link bring-up, thriving at the intersection of hardware engineering, systems integration, and customer-facing applications.

Requirements

• Bachelor’s degree or higher in Electrical Engineering, Computer Engineering, Physics, or a related field.
• Strong understanding of optical transceivers, including module architectures, control interfaces, configuration protocols, and performance metrics.
• Extensive hands-on experience with DSP tuning, optical transceiver configuration, and high-speed link bring-up and debug.
• Deep familiarity with AI networking switch architecture, host electrical interfaces, and system-level integration of optical modules.
• Hands-on experience with lab equipment such as oscilloscopes, BERTs, VNAs, protocol analyzers, or similar tools used for hardware validation.
• Working knowledge of signal integrity, power integrity, thermal considerations, and hardware validation methodologies for high-speed systems.
• Excellent analytical, communication, and customer-facing skills, with the ability to translate complex hardware and system issues into actionable solutions.
• Ability to work independently in fast-paced environments and collaborate effectively across dispersed, cross-functional teams.

Nice To Haves

• Experience working with 800G modules, 1.6T architectures, or 51.2T switches is highly desirable.
• Prior experience with leading optical-transceiver or networking-system companies is a strong plus.

Responsibilities

• Lead hardware-focused system integration for 51.2T and next-gen switches, including optical module bring-up, lab validation, and performance verification for 800G/1.6T transceivers.
• Serve as the primary technical interface for customers, translating system requirements into practical hardware validation plans and deployment guidance.
• Debug complex interoperability issues spanning optical modules, DSP settings, host interfaces, switch platforms, and Layer 1 link behavior.
• Execute board- and system-level testing using lab equipment such as oscilloscopes, BERTs, VNAs, and protocol analyzers to characterize link performance and root-cause failures.
• Collaborate across optical, hardware, signal integrity, thermal, mechanical, and software teams to ensure robust integration of optical modules into AI networking environments.
• Review schematics, layouts, and system configurations to identify signal integrity, power integrity, and integration risks during bring-up and qualification.
• Develop and maintain test procedures, characterization reports, application notes, and supporting scripts or tools to improve validation efficiency and customer support.
• Stay current on industry standards and emerging technologies in AI networking, optical transceivers, module management, and high-speed electrical/optical interfaces.

Benefits

• Competitive salary and significant equity compensation in a rapidly growing, well-funded startup.
• Comprehensive health, dental, and vision insurance.
• Flexible time off policy.
• Direct impact on groundbreaking technology shaping the future of AI and data centers.
• Opportunity to work with a highly experienced and collaborative team.
• Dynamic and innovative work environment
• Opportunity for rapid career growth
