radiant - Senior/Principal Product Manager - Cluster Platform
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: GPU servers, bare metal, provisioning, firmware, hardware validation • Networking: high-performance fabrics, RDMA, InfiniBand/Ethernet, topology • Storage: distributed storage, throughput, latency, data paths • Orchestration: Kubernetes, Slurm, containers, schedulers • Automation: infrastructure-as-code, configuration management, workflow engines • Observability: telemetry, health checks, diagnostics, performance monitoring • 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. • Set the standard: Every single day, you spot opportunities to constructively shake things up • Inspire the change: There’s no blueprint for the future. You’ll embrace challenges and change • You’re real and you’re true to yourself: We cherish and celebrate diversity so you’ll feel right at home whoever you are and whoever you’re talking to, you treat everyone the same.
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. • Health & Wellbeing: we want everyone to feel healthy and happy, so we offer private medical insurance via Bupa. • Cycle to Work Scheme: we're committed to building a sustainable business, so we encourage cycling to work. • Gympass subscription to a variety of gyms and wellbeing apps • Participation in the company shares program • Enhanced parental pay & leave
