Design and implement internal software and data-collection tools for eHDD validation. Build ETL pipelines, web apps, analytics/ML models, and tooling that interface with firmware and low-level system layers. Work across Windows/Linux environments, databases, and distributed systems to automate tests, analyze servo-mechanical behavior, and accelerate HDD product development.

Lead development of Python-based tools and automation frameworks for optical transceiver validation. Automate test execution, instrument control, data collection/analysis, CMIS and EEPROM verification, and support qualification of PAM4, LPO/LRO, and coherent optics for 1.6T and 12.8T platforms.

Design and build scalable automation, testing, and infrastructure for NVIDIA deep learning libraries across platforms. Develop full-stack tools from UIs to cluster and database layers, configure CI/CD, and advance industry-standard tooling to improve build, test, integration, and release workflows.

Develop, integrate, debug, and test Cisco Silicon One software and datapath applications. Collaborate with hardware, systems, partners, and customers on networking protocols, system integration, and diagnostics; add features, tests, and documentation to support product quality and customer deployment.

Design and implement DPU-based packet-processing pipelines and SDK integrations. Build firewall, ACL, NAT, tunneling, load-balancing, telemetry and host offload features. Develop across firmware/SDK, host drivers, Arm services, and user-space control. Debug across host/DPU/firmware/kernel boundaries, validate performance and scale, own features end-to-end, and contribute to reviews, documentation, and mentoring.

Lead design and implementation of Switch Abstraction Interface (SAI) software for network switches, align SONiC models with SAI goals, drive architecture, optimize performance and serviceability, represent Cisco in the SAI open-source community, and mentor engineers while collaborating with hardware teams.

Lead development and migration to a workflow-as-code management plane (Temporal) to provision and operate a global fleet (100k+). Build idempotent, replay-safe workflows, orchestration-ready platform APIs, AI/ML-driven SRE features, and deep telemetry for explainable, auditable fleet operations.

The Senior Distributed Storage System Engineer will lead project teams, design software systems, mentor staff, and drive innovation in solutions design.
