Upscale AI is a Santa Clara–based startup building synchronized AI-cluster networking that integrates GPUs, accelerators, storage and networking.
Why join Upscale AI Upscale AI is building the high-performance infrastructure powering the next generation of artificial intelligence. Backed by over $300M in funding and rapid global adoption, we are scaling systems designed for the world’s most demanding AI workloads. We focus on first-principles engineering across silicon, systems, and networking—where performance, scale, and execution are critical. Our team is talent-dense and high-performing. We value ownership, technical rigor, and speed, and we offer the opportunity to work on foundational problems with immediate, real-world impact. If you’re looking to do high-impact work, move fast, and help define the infrastructure behind the future of AI—Upscale AI is where you can produce meaningful work at the frontier—and operate at a high standard. We are seeking a highly skilled gNMI Engineer with strong expertise in SONiC (Software for Open Networking in the Cloud), network programmability, telemetry, and automation. The ideal candidate will be responsible for developing, integrating, and maintaining gNMI-based management and telemetry solutions for SONiC-enabled network devices. The role requires good understanding of YANG models, OpenConfig, gRPC/gNMI protocols, and modern datacentre networking technologies. The engineer will work closely with SONiC developers, automation teams, and cloud infrastructure teams to build scalable network management and observability solutions. What will you do ? • Design and implement gNMI-based configuration and telemetry solutions for SONiC switches. Maintain gNMI clients, servers, and related services. • Integrate SONiC management interfaces with OpenConfig and vendor-specific YANG models. • Enhance manageability solutions using gNMI Subscribe, Get, Set, and Capabilities operations. Implement streaming telemetry solutions using: gNMI and OpenConfig • Support integration of SONiC with data center orchestration platforms. • Troubleshoot and optimize gRPC/gNMI communication for large-scale deployments. • Contribute to SONiC management framework enhancements. • Develop automation frameworks using: Python, Go (Golang) • Debug protocol-level issues involving: gRPC, gNMI, OpenConfig, YANG, perform packet captures and protocol analysis. • Resolve scalability and performance issues in telemetry systems.
