About the role
What You'll Do
As a Software Engineer - Network, you will help build the software that runs our cluster networks: the fabric connecting thousands of GPUs, and the Managed Networks our customers rely on.
You'll work alongside senior engineers on the Network team, owning features end to end and growing your expertise in high-performance networking.
Key Responsibilities
Build and maintain services that configure, monitor, and automate our network fabric.
Turn manual network operations into reliable, tested software.
Own features from design through production, with support from senior engineers.
Join the team's on-call rotation as you ramp up.
Contribute to code review and team practices.
Your Profile
Experience building production software, ideally in Go or similar.
Solid networking fundamentals: TCP/IP, routing, switching.
Experience with APIs and distributed services.
Comfortable working in Linux.
Curious, and keen to learn high-performance networking.
What You Bring
Curiosity: Want to understand how the network works, all the way down.
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.
Qualities 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.
Why 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.
Company 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.
