Engineering Manager

About this role

About the role Radiant exists to redefine how AI infrastructure is built and operated at scale. We are creating a vertically integrated AI platform that brings together physical infrastructure, control planes, and cloud-native software to deliver abundance, control, and sovereignty in a world constrained by traditional hyperscaler models. Our vision is to enable organisations to build, train, and deploy AI at national and global scale without surrendering control over performance, cost, or locality.

This requires engineering systems that operate across software, hardware, and physical environments, and that remain reliable as scale and complexity increase. We are scaling our engineering organisation now. Most of our engineering manager seats are open. You join, shape how the teams work, and grow with them. As an Engineering Manager, you lead a team building and operating core parts of Radiant's cloud platform. You combine people leadership, technical judgement, delivery ownership and cross-functional collaboration.

You work closely with product, infrastructure, SRE, security and other engineering teams. This is a hands-on leadership role. It focuses on building strong teams, delivering reliable platform capabilities, and creating an environment where engineers do their best work. The streams We run engineering as ten streams in three groups. Each stream is a full team of about nine people: principal, senior and mid-level software engineers, an SDET, a DevOps engineer and a platform engineer.

Each stream has its own engineering manager. Infrastructure: Compute, Network, Storage, Cluster Platform: Cloud, Infra, Observability, Security AI: Training, Inference You do not apply for a single stream. We hire strong managers first. Then we agree your stream with you, based on your strengths and interests. Your first stream is a starting point, not a fixed track. Moves between streams are normal here. Key responsibilities You lead one stream end to end: people, delivery and production.

Lead, coach and develop a team of about nine engineers across platform, infrastructure and distributed systems. Own team execution across planning, prioritisation, delivery, quality and operational readiness. Partner with product to turn priorities into clear technical plans and achievable milestones. Provide technical leadership on architecture, reliability, scalability and engineering trade-offs. Set strong engineering practices for design, testing, observability, documentation and incident learning.
