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.
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. 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.
Modern stack, real scale: Kubernetes at scale, a full observability platform, GitOps everywhere - all on-prem in a high-performance trading environment. Greenfield opportunities. Bare metal K8s, advanced observability, automated dependency mapping, AI infrastructure - there's no shortage of interesting projects. 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.
Responsibilities:
- 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.
- 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).
- 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).
- Infrastructure as Code: Terraform and/or Ansible for provisioning and configuration management.
- Linux systems: Strong fundamentals - systemd, networking, storage, performance troubleshooting.
- Programming: Go or Python for automation, tooling, and scripting. Comfortable reading and writing YAML and Helm charts.
- 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.
Qualifications:
- Preferred Skills: 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.
