In Office Senior EMEA Materials Senior DevOps Engineer Go YAML Helm Python Kubernetes

Requirements

• 5–8 years of experience in DevOps, SRE, or Platform Engineering roles. • Kubernetes: Deep hands-on experience operating K8s in production. Cluster lifecycle, troubleshooting, networking, storage, RBAC. Experience with Cluster API, bare metal provisioning, or multi-cluster management is a strong plus. • Kubernetes: • Observability: Production experience with Prometheus, Grafana, and alerting. Familiarity with Mimir, Loki, Tempo, or Thanos for scaled metrics, logs, and traces. Understanding of OpenTelemetry (collectors, exporters, instrumentation). • Observability: • GitOps and CI/CD: Experience with ArgoCD, Flux, or similar GitOps tools. Building and maintaining CI/CD pipelines (GitLab CI, GitHub Actions, or equivalent). Artifact management (Artifactory, Nexus, or similar). • GitOps and CI/CD: • Infrastructure as Code: Terraform and/or Ansible for provisioning and configuration management. • Infrastructure as Code: • Linux systems: Strong fundamentals — systemd, networking, storage, performance troubleshooting. • Linux systems: • Programming: Go or Python for automation, tooling, and scripting. Comfortable reading and writing YAML and Helm charts. • Programming: • Communication: Ability to work directly with trading desks and development teams who depend on the platforms you build. You'll be explaining K8s concepts to people who aren't K8s experts. • Communication: • Experience working at a trading firm — understanding the urgency and reliability requirements of systems that support P&L-impacting workloads. • Experience with Kubeflow, Airflow, or ML pipeline orchestration. • Experience with advanced Kubernetes networking (CNI plugins, network policies, service mesh). • Experience with Kafka or event streaming platforms. • Experience operating on-prem infrastructure (not just cloud) — bare metal servers, IPAM, storage systems. • Thoughtful use of AI coding assistants and interest in AI-assisted operational tooling.

Responsibilities

• Kubernetes platform operations and evolution: Cluster lifecycle management via Cluster API, fleet-wide upgrades, bare metal provisioning, CNI networking, storage, autoscaling, and disaster recovery planning. • Kubernetes platform operations and evolution: • Observability: Operate and scale our on-prem observability stack — Mimir (metrics), Loki (logs), Tempo (traces), Grafana (dashboards), OpenTelemetry Collector fleet, and Alertmanager. Drive adoption by onboarding teams, building dashboards, tuning alerts, and scaling ingestion for growing workloads. • Observability: • CI/CD and GitOps: GitLab pipelines, ArgoCD for Kubernetes deployments, Artifactory for artifact management. Build reusable CI components, improve secrets integration, and support trading desks onboarding to the platform. • CI/CD and GitOps: • Infrastructure automation and tooling: Build and maintain automation for provisioning, configuration management, and self-service tooling that enables teams across the firm to move faster without depending on DevOps for every change. • Infrastructure automation and tooling: • Platform adoption and support: Work directly with trading desks and development teams to onboard them to the platforms we build. Write runbooks, contribute to documentation, and help build a sustainable support model as the platform scales. • Platform adoption and support:

Benefits

• Ownership, not tickets. This is a growing team that built and owns the entire platform. You'll have direct impact on infrastructure that trading desks depend on daily. • Ownership, not tickets. • Modern stack, real scale. Kubernetes at scale, a full observability platform, GitOps everywhere — all on-prem in a high-performance trading environment. • Modern stack, real scale. • Greenfield opportunities. Bare metal K8s, advanced observability, automated dependency mapping, AI infrastructure — there's no shortage of interesting projects. • Greenfield opportunities. • Small team, big impact. You won't get lost in a 50-person platform org. Every engineer on this team shapes the direction of the platform. • Small team, big impact.
