Requirements
• DevOps and platform operations background – significant experience in a platform operations, DevOps or SRE role, with a track record of improving reliability, observability and developer experience in a fast moving engineering environment. • Observability stack expertise – deep familiarity with the Grafana ecosystem, including Loki for log aggregation, Mimir or Prometheus for metrics, and Grafana for dashboarding and alerting. Experience designing observability strategies for distributed systems. • FinOps and cost observability – practical experience implementing cloud cost attribution and reporting across multi cloud or multi tenant environments, including familiarity with tools such as OpenCost, Kubecost or cloud native cost management consoles. • Kubernetes knowledge – solid operational familiarity with Kubernetes, sufficient to deploy, debug and manage platform components and understand how infrastructure decisions affect operational outcomes. • Security awareness – lightweight but genuine experience with security tooling, including policy enforcement (OPA, Kyverno or equivalent), audit logging and vulnerability scanning integrated into delivery pipelines. • Multi cloud familiarity – experience working across more than one cloud provider, with an appreciation for the differences in IAM, networking and cost models. • Software engineering capability – you are comfortable writing scripts and tooling to automate operational tasks. Python is the primary language expected; Golang familiarity is a bonus. Interviews will include a coding element. • Communication and collaboration – you can translate operational data and platform health into clear, actionable insight for engineering teams and leadership. • Ideally • Experience with Terraform or Crossplane for infrastructure provisioning, even if infrastructure ownership sits with a separate team. • Familiarity with GitOps workflows using Argo CD, Flux or equivalent tooling. • Experience with on premises or hybrid infrastructure environments. • Background in ML platform, simulation or HPC operational environments. • Kubernetes certifications such as CKAD or CKA are a welcome indication of structured Kubernetes knowledge. • Exposure to functional programming languages such as Erlang, Elixir or OCaml.
Responsibilities
• Own and evolve the platform monitoring and observability stack, including Grafana, Loki, Mimir and associated alerting and dashboarding practices. • Define and maintain SLO dashboards and alerting policies that give platform and product teams clear visibility into system health. • Lead the adoption and operation of Backstage as the internal developer portal, building and maintaining plugins, service catalogue entries and golden path templates that improve the developer experience across PhysicsX. • Drive FinOps practices across the platform, including cloud cost attribution, showback and chargeback reporting, and cost anomaly detection across multi cloud environments. • Implement and maintain IAM and permissions policies across GCP, Azure and equivalent cloud providers, ensuring least privilege access is enforced consistently. • Contribute to lightweight security practices including audit logging, vulnerability scanning integration in CI pipelines and policy enforcement using tools such as OPA or Kyverno. • Collaborate with Core Infrastructure and Runtime teams to surface operational insights and feed operational learnings back into infrastructure and runtime design. • Drive incident response practices, including runbook creation, post mortem facilitation and reliability improvement initiatives. • Contribute automation and tooling in Python or Golang to reduce toil and improve platform operability.
