About the Role

As a Senior/Principal Product Manager - Cluster Platform, you will own the product experience and operational lifecycle for bringing new AI infrastructure clusters onto Radiant’s platform. You’ll work across cluster onboarding, acceptance, validation, provisioning and automation, partnering closely with infrastructure, SRE, networking, storage, platform engineering, operations, and hardware teams. This is a highly technical product role focused on making AI cluster deployment repeatable, measurable, automated, and production-ready at scale.

Responsibilities

Own the strategy, roadmap, and delivery for cluster onboarding, validation, acceptance, and lifecycle management.
Define the end-to-end process for taking new infrastructure from installed hardware to production-ready cluster.
Productise and automate workflows across discovery, provisioning, configuration, testing, benchmarking, acceptance, and handover.
Define cluster readiness and acceptance criteria across compute, GPUs, networking, storage, firmware, software, and reliability.
Partner with engineering to build tooling and automation for cluster deployment, validation, remediation, and lifecycle operations.
Define benchmarking frameworks for GPU performance, network fabric, storage throughput, collective communication, and workload performance.
Build clear visibility into cluster state, readiness, failures, exceptions, and deployment progress.
Identify recurring deployment friction and turn operational processes into scalable platform capabilities.
Drive prioritisation, technical requirements, delivery, adoption, and continuous improvement across the cluster lifecycle.
Define success metrics across time-to-ready, automation coverage, acceptance pass rates, deployment reliability, and cluster performance consistency.

Requirements

Experience owning technical infrastructure, cloud platform, data centre, HPC, or AI infrastructure products.
Strong understanding of the lifecycle involved in deploying and operating large-scale compute or GPU clusters.
Strong technical fluency across compute, networking, storage, orchestration, and automation.
Familiarity with benchmarking and validation tools such as NCCL tests, HPL, MLPerf, GPU diagnostics, network and storage benchmarks, or similar.
Strong understanding of failure handling, repeatability, configuration drift, acceptance testing, and operational automation.
Able to work across hardware, software, infrastructure, and operations teams to drive a single product outcome.
Strong prioritisation, communication, and stakeholder management skills.
Cluster systems thinking: Understand how compute, GPUs, networking, storage, software, and orchestration interact as a complete system.
Product mindset: Turn manual deployment and acceptance processes into repeatable platform capabilities.
Technical fluency: Work credibly with engineering teams across hardware and software layers.
Operational discipline: Care about repeatability, quality gates, validation, and measurable readiness.
Automation mindset: Look for opportunities to eliminate manual steps and reduce deployment variance.
Ownership: Drive clusters from onboarding through acceptance, production readiness, and continuous improvement.
