The role
This is a defence AI company. Their mission is to protect democracies, building critical technology that ensures open societies can make sovereign decisions. They're solving some of the hardest real-time AI problems in high-security, on-premise environments, backed by significant funding from leading investors and growing rapidly with hundreds of engineers across Europe from top-tier tech companies.
You'll own the infrastructure that makes this mission possible. This isn't just another cloud ops role; you'll design and build cloud-native platforms on-premises – secure, multi-tenant Kubernetes clusters with zero-trust networking and policy-as-code governance. You'll develop the automation that allows development teams to operate services at scale, ensuring reliability and compliance in environments where the stakes are exceptionally high.

Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
