Senior DevOps Engineer

01What You'll Do

As a Senior DevOps Engineer, you will be embedded in one of our engineering teams, not in a central team, owning how that team builds, tests, ships, and runs its software.

You'll work day to day with the team's software engineers, and closely with platform engineers, SRE, and Infra Ops.

The teams

• Infra

• Network

• Cloud

• Observability

• MLOps

02Key Responsibilities

• Build and run CI/CD pipelines and release processes.

• Automate infrastructure and environments as code.

• Improve monitoring, alerting, and incident response.

• Make it fast and safe for engineers to ship.

• Take part in on-call and incident response.

03Your Profile

• Solid experience in DevOps, platform, or SRE roles.

• Strong CI/CD and infrastructure-as-code experience (e.g. Terraform, Ansible, GitHub Actions).

• Kubernetes and containers in production.

• Scripting or coding skills, ideally in Go or Python.

• Calm and methodical in incidents.

04What You Bring

• Automation instinct: If you do it twice, you automate it.

• Engineering quality: Write clean, tested, maintainable code, and review others' work with care.

• Ownership: Take features from design through production, and stay accountable for how they run.

• Pragmatism: Ship what matters, simply, and improve it from real-world feedback.

• Collaboration: Work openly with product, infrastructure, SRE and customers, and share what you learn.

05Qualities we look for

• 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.

06Why should you join us?

What sets us apart is our blend of modern technology, competitive benefits, and an open, welcoming work culture that enables our people to thrive.

Here are just some of the great things you can expect from us:

• 25 days of annual leave

• A culture that emphasises results over hierarchy, process & ego: we place great emphasis on the quality, ingenuity and creativity of work.

• Open communication, regular feedback: we value smooth collaboration, direct and actionable feedback, and believe that leading with empathy and a growth mindset makes us better together.

• Learning Time: we all have dedicated learning time to focus on new skills, projects or interests that lay outside of your day-to-day job.

• 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

Our process: Talent screen → Hiring Manager → Technical interview (two engineers) → Final.

07Company Overview

Radiant is redefining how AI infrastructure is built.

We design and operate AI-native cloud platforms engineered for sovereignty, performance, and scale. Our infrastructure powers GPU-native workloads, multi-tenant control planes, and high-performance AI systems designed for the most demanding environments.

We are not building a generic cloud. We are building purpose-built AI infrastructure - from powered land, to compute, to software.

As we scale, we're building this organisation from the ground up. We're looking for people who'd rather build the playbook than inherit one - who are comfortable doing the work themselves as well as directing others, and who can adapt as fast as our strategy does. This is a startup model: attitude and adaptability matter more to us than years of experience or the size of the team you've previously managed.
