Description

Overview Connecting clients to markets – and talent to opportunity.With 4,500+ employees and over 300,000 commercial, institutional, payments, and retail clients, we operate from more than 70 offices spread across six continents. As a Fortune 100, Nasdaq-listed provider, we connect clients to the global markets – focusing on innovation, human connection, and providing world-class products and services to all types of investors.Whether you want to forge a career connecting our retail clients to potential trading opportunities, or ingrain yourself in the world of institutional investing, StoneX Group is made up of four business segments that offer endless potential for progression and growth. Responsibilities Position Purpose: Join the Automation & Containers team to build, run, and continuously improve our Kubernetes-based platform. You’ll handle the usual operational support while driving platform evolution -scalability, performance, automation, and a great developer experience—so delivery is fast, secure, and auditable by default. Primary duties will include: Operate and evolve Kubernetes (Rancher/RKE2 or AKS): upgrades, scaling, performance tuning, cost/capacity management, backup/restore, and HA patterns. Design automation and golden paths: Terraform modules, Helm/Kustomize templates, reusable GitHub Actions workflows, and self-service onboarding. Implement and maintain GitOps with Argo CD: digest-pinned deployments, policy-as-code, image signing/SBOM, drift detection, safe rollbacks. Harden CI/CD: environment protections, approvals, OIDC-based cloud access, immutable audit trails; keep pipelines fast and compliant. Manage supply chain & registries (ACR): immutability, vulnerability scanning, promotion strategies. Own observability for the platform (Datadog/Prometheus, Graylog/Splunk): SLOs, dashboards, actionable alerts, and capacity hygiene (incl. ephemeral storage/emptyDir). Partner with dev/infra teams on onboarding, troubleshooting, runbooks, and incident response; participate in an on-call rotation. Uphold security & compliance guardrails (RBAC, secrets management, SoD, change controls) without slowing delivery. Qualifications To land this role you will need: 3+ years in Platform/SRE/DevOps roles with production Kubernetes experience. Hands-on with GitOps and modern CI/CD (example: Argo CD, GitHub Actions and/or Azure DevOps). Infrastructure as Code (Terraform), packaging (Helm/Kustomize), and solid Linux/networking fundamentals. Scripting for automation (Bash and/or Python); comfortable with YAML-first workflows. Experience operating logging/metrics/tracing stacks and troubleshooting complex distributed systems. What makes you stand out: Rancher/RKE2 or AKS depth; policy-as-code (Kyverno/Gatekeeper); cosign image signing & SBOM (Syft/CycloneDX). ACR governance, artifact promotion, and immutable tagging; self-hosted runner hardening. Exposure to SOX/SOC-aligned CI/CD controls and evidence practices. Education: Bachelor's degree in Computer Science, or a combination of education and/or equivalent experience. Working environment: Hybrid; our Cracow office is located at Mogilska 35 street. Parking space for employees. #LI-Hybrid #LI-MA1
