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 backend services, APIs, and control plane workflows that power a multi-tenant GPU cloud platform. This role will sit at the core of the product and turns infrastructure capabilities such as provisioning, identity, metering, deployment, and orchestration into reliable platform services consumable by internal teams, customers, and user-facing applications. This role is primarily backend-driven, but also includes delivery of user-facing platform interfaces using TypeScript/JavaScript and AI-assisted frontend development. You will build the platform logic behind the GPUaaS offering. You will work on the control plane that connects cloud infrastructure, workflow orchestration, identity, billing and usage metering, and platform lifecycle operations into a coherent product. You will design and implement backend services in Go, expose clean and secure APIs, and translate infrastructure primitives into product-grade platform capabilities. This includes provisioning flows, image and deployment workflows, service integration, state handling, auditability, and operational reliability across distributed systems. You are comfortable working at the intersection of software engineering and cloud platform design. You understand that backend services in this environment are not only CRUD APIs, but part of a larger orchestration layer coordinating CloudStack, Kubernetes, container runtimes, identity systems, metering, messaging, and observability stacks.
What you’ll do
- Design, implement, and maintain backend platform services in Go.
- Build and evolve control plane APIs for platform and product capabilities.
- Develop durable provisioning and lifecycle workflows using orchestration patterns.
- Build and maintain frontend and control plane UI components using TypeScript/JavaScript.
- Use AI-assisted development tools to accelerate frontend implementation, iteration, and refactoring.
- Integrate infrastructure systems such as CloudStack, Kubernetes, container runtimes, and image management into product APIs.
- Connect platform services with identity, usage metering, billing, and audit systems.
- Model platform state and service interactions across distributed components.
- Build robust integrations with systems such as Temporal, Keycloak, OpenMeter, MongoDB, PostgreSQL, RabbitMQ, Kafka, Redis, and ClickHouse.
- Ensure backend services are secure, observable, testable, and operationally reliable.
- Collaborate closely with DevOps, and infrastructure engineers to deliver end-to-end platform features.
- Contribute to engineering standards, service design patterns, and API quality across the platform.

- Comfortable designing integrations with infrastructure APIs and external platform components.
- Experience with distributed systems, asynchronous workflows, and event‑driven patterns.
- Strong understanding of reliability, state management, idempotency, and failure handling in orchestration-heavy systems.
- Able to translate low‑level infrastructure capabilities into productized platform services.
- Experience with identity, provisioning, metering, billing, or control plane systems is a strong plus.
- Familiarity with Kubernetes and cloud infrastructure concepts is highly desirable.
- Pragmatic, hands‑on, and able to balance speed with maintainability and operational quality.
- Able to independently own major components or features from design through production rollout.
