Define infrastructure standards, operational boundaries, security controls, and deployment patterns across the platform. Work closely with engineering teams to make services easier to deploy, operate, monitor, and debug. Contribute to the long term technical direction of the DevOps department and the infrastructure foundations of ACRA. What we are looking for: Strong experience in infrastructure engineering, platform engineering, DevOps, SRE, or production systems engineering. Deep hands on experience operating Kubernetes in production. Strong understanding of Linux systems, containers, networking, storage, and distributed infrastructure. Strong networking fundamentals, including TCP/IP, DNS, TLS, routing, load balancing, ingress, egress, network policy, and service discovery. Experience with Kubernetes networking, CNI, service mesh, or secure service to service communication. Experience debugging difficult infrastructure issues across clusters, nodes, pods, networks, storage, and workloads. Experience with infrastructure as code and GitOps workflows, especially Terraform, Argo CD, Helm, or Kustomize. Experience building reliable infrastructure for production environments where uptime, security, and operational clarity matter. Comfortable working across cloud, on premise, bare metal, restricted, or customer managed environments. Strong operational judgement, especially around reliability, resilience, failure domains, and production risk. Strong ownership mindset. You can take responsibility for critical systems and improve them over time. Clear communication skills. You can explain complex infrastructure problems to engineering and leadership without adding noise. Comfortable working in a startup environment with ambiguity, changing priorities, and broad technical responsibility. Nice to have: Experience with distributed storage systems, especially Rook Ceph or Ceph. Experience with Cilium, eBPF, cluster mesh, Istio, Envoy, or similar networking and service mesh technologies. Experience with multi cluster Kubernetes environments. Experience operating infrastructure in secure, regulated, sovereign, air gapped, defence, government, fintech, healthcare, critical infrastructure, or customer managed environments. Experience with zero trust architecture, workload isolation, identity aware networking, policy enforcement, or runtime security. Experience with secrets management tools such as Vault, OpenBao, SOPS, Sealed Secrets, External Secrets, or cloud native secret managers. Experience with supply chain security, including image signing, vulnerability scanning, SBOMs, artefact verification, admission control, or policy as code. Experience designing infrastructure where auditability, traceability, and operational evidence are first class requirements. Benefits: Equity - because you have the right to own what you're building. A competitive salary - because we value your unique skills. Employer pension contributions - because you deserve a secure future. Hybrid work setup - because everyone has different needs. Rewarding company retreats and meetups that respect your work/life balance - because we love getting to know each other! Life at Valarian Our culture is built on inclusivity, compassion and flexibility - we want everyone to be empowered to achieve their goals at Valarian. The world is changing, and so is our way of working. If you want to join us in the London office - it's quite nice! - you're welcome to; and if you'd prefer to work remotely, that's fine too. And as we build elegant solutions to simplify the complexities of business collaboration, we also simplify work life: contribute wherever and whenever allows you to be your best self. We trust each other to consistently raise the bar, and we challenge each other to continually reach new heights.
