## Description

We are seeking a highly skilled System Application Engineer (Software) 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 software integration, API-level control, automation, and system-level debugging. The ideal candidate brings deep experience with switch OS/SDKs, DSP and module configuration tools, embedded software workflows, and high-speed link bring-up-thriving at the intersection of software engineering, systems integration, and customer-facing applications., * Lead software-driven system integration for 51.2T and next-gen switches, including API configuration, automation frameworks, and module management for 800G/1.6T optical transceivers.

 * Serve as the primary technical interface for customers, interpreting system requirements and delivering software-supported, end-to-end solutions.
 * Debug complex interoperability issues spanning switch OS/SDKs, DSP firmware, protocol stacks (L1/L2), and optical module control interfaces.
 * Create and run customer demos, software workflows, and validation scripts, including switch bring-up, link diagnostics, and performance verification.
 * Collaborate across software, optical, hardware, thermal, and mechanical engineering teams to ensure clean, scalable integration of optical modules into AI networking environments.
 * Develop scripts, tools, and automation (Python or similar) to accelerate triage, link tuning, and test execution.
 * Stay current on industry standards and emerging technologies in AI networking, module management protocols, and switch software architectures.
