Quantori is seeking a Senior Platform Engineer to build a hybrid HPC platform across AWS and on-premises environments for a global agricultural science company. You will own the platform foundation, including infrastructure, the Kubernetes cluster for platform services, CI/CD pipelines, identity management, networking, and security.

You will work across teams to ensure reproducible environments, implement secure access controls, and monitor and scale automation across compute pools and services.

Qualifications

• 5+ years of experience in DevOps, Platform, or Cloud Engineering with production ownership.
• Strong hands-on AWS experience (VPC, IAM, EKS, EC2, S3, KMS) and Terraform.
• Strong Linux administration skills and Ansible experience.
• Production experience with Kubernetes, Helm, and Argo CD.
• Experience building CI/CD pipelines with GitLab CI or GitHub Actions.

• Experience with HashiCorp Vault for secrets management.
• Solid networking knowledge: routing, DNS, firewalls, site-to-site IPSec VPN and hybrid cloud connectivity.
• Python and Bash scripting for automation.
• Ability to work independently and communicate directly with client IT, network and security teams.

Responsibilities

• Provision AWS infrastructure with Terraform and configure Linux hosts in AWS and the external data center with Ansible, so every environment can be rebuilt from code.
• Build and run a Kubernetes cluster for shared platform services (observability, Keycloak, HashiCorp Vault, web applications), delivered through GitOps with Argo CD and Helm.
• Build and maintain GitLab CI pipelines for infrastructure and platform services.
• Integrate corporate SSO through Microsoft Entra ID and keep user and group IDs consistent across all sites and compute pools.
• Set up monitoring and alerting across compute pools and platform services with Prometheus and Grafana.
