We are looking for a Senior Infrastructure Engineer to own and evolve the foundational infrastructure layer behind ACRA.
This is a deep infrastructure role. You will work across Kubernetes, Linux, networking, storage, service-to-service communication, observability, security boundaries, and production operations. You will be responsible for the systems that everything else depends on: clusters, networks, storage layers, ingress and egress paths, runtime infrastructure, deployment foundations, and operational reliability.
Infrastructure is part of the product at Valarian. ACRA only works if the underlying infrastructure is secure, observable, debuggable, resilient, and able to run across cloud, on-premise, bare-metal, sovereign, air-gapped, and customer-managed environments.
We are looking for someone with strong judgement and real production experience. This role values depth, operational correctness, and careful decision-making. You should be comfortable going deep into complex operational problems, understanding failure modes, debugging under pressure, and improving the reliability of the whole platform.
You should be comfortable operating close to the metal: debugging Kubernetes, understanding networking behaviour, reasoning about distributed storage, improving observability, and helping define the infrastructure patterns that ACRA will rely on as it scales.
This is not a generic DevOps support role, cloud administration role, or internal IT role. You will be a critical engineer in the team responsible for the infrastructure foundations of a high-trust platform.
