Join a senior team of DBAs and SREs to scale and tune distributed MariaDB environments, strengthen HA and disaster-recovery, reduce manual work via automation and IaC (Terraform/GitOps), improve observability and security, and participate in on-call rotations. Positions listed for multiple European countries and several other locations.

Join NVIDIA's DGX Cloud team to build, implement and support operational and reliability aspects of large-scale Kubernetes clusters focused on performance at scale. The role requires defining SLOs/SLIs, operating GPU workloads across AWS/GCP/Azure/OCI and private clouds, building observability stacks, automating infrastructure, participating in on-call rotation, and leading incident triage; 10+ years of production operations experience and expertise in Kubernetes, Linux, cloud platforms, and SRE practices are required.

Role involves architecting, deploying, and tuning large-scale HPC and AI clusters (CPU/GPU), managing job scheduling and orchestration (e.g., Slurm, Kubernetes), developing CI/CD pipelines and automation, deploying monitoring/logging/alerting, troubleshooting from bare metal to application level, and supporting R&D and POCs. Requires strong Linux/Windows, networking, storage, scripting, and virtualization knowledge.

Wikimedia Foundation is hiring a Senior Site Reliability Engineer for Wikimedia Enterprise to design, develop, and maintain reliable, scalable infrastructure for high-volume API services. Responsibilities include defining SLOs/SLIs, building observability, running Kubernetes and cloud infrastructure, implementing CI/CD/GitOps (e.g., GitLab, ArgoCD), incident response and on-call duties, and collaborating with distributed teams. Strong SRE, cloud, IaC, observability, and automation skills are required.

Join Wikimedia Foundation as a remote Senior Site Reliability Engineer focused on data persistence. Responsibilities include operating and automating public-facing infrastructure (deployment, configuration, troubleshooting), using tools like Puppet and Kubernetes, collaborating with product teams, participating in a 24/7 on-call rotation and incident response, and mentoring peers. Requires 6+ years SRE/Operations/DevOps experience and strong English; preferred experience includes Prometheus/Grafana, Ceph/OpenStack Swift, distributed storage/databases, and LAMP technologies.

Join a senior team of DBAs, SREs, and platform engineers to scale PostgreSQL and vector search infrastructure, strengthen HA/DR and backup practices, build automation and GitOps workflows, improve observability and security, and collaborate with service and AI teams. Requires 5+ years operating PostgreSQL in high-volume production environments.

Role involves in-depth performance characterization and analysis on large multi-GPU/multi-node clusters, studying HW/SW interactions, implementing micro-benchmarks, triaging customer performance issues, and building tools to visualize performance data. Requires M.S. or equivalent (or PhD), 3+ years of parallel programming and communication runtime experience (e.g., MPI, NCCL, UCX, NVSHMEM), proficiency in C/C++ and a scripting language (preferably Python), and familiarity with containers, cloud provisioning and schedulers (Kubernetes, SLURM, Ansible, Docker).
