About Radian Arc
Radian Arc, now part of InferX, Submer's AI cloud and GPU infrastructure platform, provides an infrastructure-as-a-service (IaaS) platform for running cloud gaming, artificial intelligence and machine learning applications inside telecommunication carrier networks. Our teams across the USA, Australia, Central Europe, Malaysia, Singapore and Japan offer telecom operators a GPU-based edge computing platform without the need for capital expenditure, facilitating low latency and improved economics for value-added services and the monetization of 5G investments.
What impact you will have
Mission: Design and build the observability platform that powers visibility, reliability, and performance insights for large-scale GPU cloud infrastructure as well as smaller edge deployments.
This role is responsible for designing and implementing key parts of the observability architecture across the platform, enabling engineering, operations, and customers to understand system behavior in real time across distributed AI workloads, GPU clusters, networking fabrics, storage systems, and edge inference environments.
You will design and operate low-latency, high-scale telemetry pipelines that collect, process, and analyze metrics, logs, and traces from infrastructure running across core datacenter clusters and smaller edge deployments. The platform you build will support internal operations, automated reliability mechanisms, and customer-facing observability experiences.
As a senior engineer, you will lead delivery of major observability initiatives, contribute to the evolution of telemetry standards and SLO implementation, and work with other teams to ensure observability is effectively integrated into the platform architecture from infrastructure to application layers.
You will collaborate closely with infrastructure, networking, storage, and platform engineering teams to provide clear visibility into performance bottlenecks, infrastructure degradation, and distributed workload behavior across both hyperscale GPU environments and smaller edge installations.
This role contributes directly to improving platform reliability by analyzing production telemetry, identifying systemic issues, and driving improvements in performance, efficiency, and operational stability across the stack.
