About the role

We are seeking a highly skilled System Application Engineer (Software) to support next-generation AI networking platforms and high-speed optical interconnects, focusing on software integration, API-level control, automation, and system-level debugging for 800G and 1.6T transceivers on 51.2T-class architectures.

Responsibilities

  • 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.

Qualifications

  • Bachelor’s degree or higher in Electrical Engineering, Computer Engineering, Computer Science, or related field.
  • Strong understanding of optical transceivers, including control interfaces, configuration protocols, and performance metrics.
  • Extensive hands-on experience with DSP configuration tools, module firmware interaction, and high-speed link debugging.
  • Deep familiarity with AI networking switch software, including OS/SDK configuration, management protocols, and Layer 1/Layer 2 behavior.
  • 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.
  • Strong proficiency with Python or similar scripting languages for automation, debug, and system-level validation.
  • Excellent analytical, communication, and customer-facing skills, with the ability to translate complex software/system issues into actionable solutions.
  • Ability to work independently in fast-paced environments and collaborate effectively across dispersed, cross-functional teams.
