About the job
Own and develop the cloud and edge infrastructure platform that supports Mariana Minerals’ engineering, mining, and mineral-processing operations.
What you'll do
- Manage Kubernetes clusters and GitOps delivery across AWS and on-premises sites, including upgrades, scaling, ingress, and DNS.
- Build self-service infrastructure and default observability so engineers can deploy and operate services independently.
- Own cloud costs, identity and secrets management, incident response, and infrastructure for ML and data workloads.
What they ask for
- 8-12+ years building and operating production infrastructure, with hands-on Kubernetes cluster operation, upgrades, and debugging.
- Experience with infrastructure as code (Pulumi, Terraform, or similar) and GitOps-style continuous delivery.
- Track record building platforms adopted by other engineers; practical observability experience with Prometheus, Grafana, and a log aggregation stack.
- Fluency in Python or TypeScript and enough AWS familiarity to make cost and architecture tradeoffs.
Nice to have
- Experience supporting ML or data-intensive workloads, such as GPU scheduling, distributed training, or pipeline orchestration.
- Experience with on-premise or edge infrastructure, industrial networks, or constrained-connectivity environments.
