• Maintain and support core infrastructure systems with deep knowledge of Linux (Debian/Ubuntu preferred). • Work close to the metal: BIOS, IPMI, RAID setups, and hardware-level diagnostics are part of your comfort zone. • Design and maintain scalable networks using VLANs, L2/L3 routing, VPNs, and especially UniFi equipment. • Automate infrastructure provisioning and operations with Ansible, Bash/Python, and Git-based workflows. • Set up and manage observability stacks, including Prometheus/Grafana for metrics and Graylog, ELK, or Loki for log centralization. • Build tooling for server discovery, config auto-generation, automated OS deployments, PXE/Preseed/Cloud-init, and strong MAAS-based provisioning. • Integrate and/or develop internal APIs for tracking compute and GPU resource allocation, as well as external APIs (billing, monitoring, OpenStack, etc.). • Deploy and maintain virtualization and orchestration systems such as OpenStack (preferably with Kolla-Ansible), Proxmox VE, or VMware ESXi. • Support container-based workloads and isolate services efficiently.

• Support system reliability and operability, contributing to monitoring, observability, and infrastructure improvements. • Work with containerised and cloud-based systems, including Docker, Nix, and AWS (e.g. ECS and Fargate). • Develop Infrastructure-as-Code in Terraform, and contribute to code across all the software stack: Nix, scripting (Nu, bash, hell), Haskell, and even a bit of Python and TypeScript. • Participate in incident response and help improve on-call, alerting, and incident management practices. • Communicate effectively in a distributed team, taking ownership and supporting collaboration and continuous improvement.

• Lead a team of DevOps engineers, including performance management, growth planning, and career development • Own the DevOps team roadmap in partnership with the Director of Platform Engineering, including quarterly priorities and capacity planning • Drive technical decisions and architecture reviews for CI/CD, infrastructure automation, and platform tooling • Collaborate with engineering, data platform, data governance, and ITOps leadership on cross-functional initiatives and shared standards • Coach engineers through code review, design feedback, and incident retrospectives • Represent the team in executive forums, including roadmap reviews, FinOps reporting, and architecture councils • Partner with the Director of Platform Engineering on AI tooling governance, including standardization on approved platforms, usage policy, and measuring engineering productivity impact • Design, build, and maintain CI/CD pipelines using GitHub Actions, including reusable workflows, self-hosted runners, and security controls • Implement and operate infrastructure as code using Terraform across multi-account AWS environments • Manage Kubernetes (EKS) clusters, including ArgoCD-based GitOps delivery, ingress, observability, and security policies • Operate secrets management with HashiCorp Vault, including dynamic credentials, JWT/OIDC auth, and External Secrets Operator integration • Build and maintain observability tooling with Grafana, OpenTelemetry, and Kubernetes-native monitoring stacks • Lead incident response and post-incident reviews, including authoring runbooks and reliability improvements • Implement security controls, governance processes, and compliance validation across the platform • Contribute to AWS network architecture, including PrivateLink, VPCs, and cross-account access patterns

• Monitor, support, and maintain production applications to ensure system availability, reliability, and performance • Review application, server, and system logs to proactively identify, troubleshoot, and resolve issues • Perform root cause analysis and implement corrective actions to prevent recurring incidents • Establish operational monitoring, alerting, and support procedures • Manage and maintain Microsoft SQL Server environments supporting enterprise applications • Lead and manage application deployments across Development, Test, Staging, and Production environments • Support an Agile, Lean, and SAFe-based environment utilizing DevSecOps, CI/CD, and related methodologies • Collaborate with development teams to improve application performance, maintainability, and deployment efficiency • Support JavaScript-based application development efforts as needed
