About Radiant
AI infrastructure company running dense, large-scale GPU and CPU compute, including the latest NVIDIA architectures, for AI training, deployment and scaling. Product is moving from generalist PMs to a vertical model where each PM owns a dedicated engineering track. Startup pace, with speed favoured over structure.
Role responsibilities
Owns the hardware and infrastructure lifecycle: what happens from new kit arriving in a DC to it running in the platform • Coordinates across support, customer, DC ops and platform teams • Owns strategy, roadmap and delivery for internal tooling, CMDB, service catalogues, operational workflows and third-party tool connections • Sets up reliable sources of truth for infrastructure, services, customers, environments, ownership and configuration • Works with SRE, infrastructure, security and support to cut operational friction and improve self-service • Build vs buy calls on third-party tooling
Team structure
Owns a dedicated engineering track under the new vertical PM model • Works right alongside engineers and is expected to challenge architecture and understand how things are built
Reporting lines
Reports to the CPO • Long-term path to Group PM for the function • To confirm: Is the CPO Sofi, and who are the key engineering peers for this track?
Essential skills & experience
Subject matter expert in hardware and infrastructure lifecycle, not a generalist PM • Strongly technical, ideally an engineering background (easier to coach PM skills than technical depth) • Experience coordinating across support, customer, DC ops and platform teams • Background in an organisation running significant on-prem infrastructure: hyperscalers, hedge funds, London Metal Exchange or similar • Technical fluency across APIs, Kubernetes and cloud, inventory and dependency data, automation, observability and security • Principal level: too senior or detached from hands-on work won't fit (e.g. an SVP at Amazon) • Actively enjoys ambiguity and speed rather than tolerating it
Desirable skills & experience
AI-specific experience not required • NetBox, ServiceNow, Terraform, Grafana, Jira or similar • Distributed systems concepts (retries, idempotency, eventual consistency, failure handling) • Open to people who've stepped back from a Head or Lead role to build a function from scratch • Red flags: more than one job lasting under a year, no technical background, too far removed from hands-on technical work
Salary
Base from £100,000 at principal level • Total package into the £200,000 range including bonus and backdated equity • Flexible for the right profile: find the person first, then make it work • To confirm: Is the bonus 30% of base?
Benefits
25 days annual leave • Dedicated learning time • Private medical insurance via Bupa • Cycle to work scheme • Gympass subscription • Company shares programme • Enhanced parental pay and…
