Lead Platform Engineer - HPC, Kubernetes

Job Description

We are looking for a Lead Platform Engineer to support a customer that develops and manages several HPC clusters across AWS, CoreWeave, GCP and other providers, operating several thousand GPUs today and scaling 10x. This role is Kubernetes-heavy and requires strong software engineering skills to operate multi-cloud platform infrastructure where misconfigurations or failed upgrades cost thousands of GPU-hours, and at this scale, new kinds of failure come up routinely.

Feel free to work remotely from anywhere across Latvia or connect with colleagues at our Riga office.

• Operate Kubernetes platforms (EKS, CKS, GKE) at significant scale, including cluster lifecycle, node pool management, networking policy, and stability during rapid growth
• Provision HPC infrastructure through CI/CD across AWS, CoreWeave, GCP and OCI, with more providers coming
• Manage job scheduling to allocate GPU compute across training and inference workloads
• Define and maintain SLIs/SLOs
• Build monitoring and alerting systems
• Take part in incident response and write post-incident reviews
• Build tooling and automation in production-quality code
• Coordinate daily with the Networking, Storage, Security and AI/ML platform teams

Requirements

• 5+ years of experience in infrastructure engineering, cloud platforms or HPC
• Expertise in Kubernetes at meaningful scale, including node pool sizing, scheduler debugging, CNI troubleshooting, and rolling upgrades across large fleets
• Proficiency in advanced Python with experience writing production-grade tools, not only scripts
• Proficiency in Terraform, writing and reviewing infrastructure as code daily
• Working knowledge of AWS, including EC2, S3, EFS and FSx for Lustre
