In this role, you will own the platform foundation, including infrastructure, the Kubernetes cluster for platform services, CI/CD pipelines, identity management, networking, and security.

Location:

Quantori is an international team: we have colleagues who work not only from office but also remotely from all over the world.

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.
• Implement encryption, key management, least-privilege access and audit logging, and support the client's security review.

What we expect:

• 5+ years of experience in DevOps, Platform, or Cloud Engineering, including ownership of production environments.
• Strong hands-on experience with AWS (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 Prometheus and Grafana.
• Experience with SSO integration (OIDC/SAML) using Keycloak and Microsoft Entra ID.
• 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.

Nice to have:

• Experience with HPC environments: Slurm, AWS ParallelCluster, Open OnDemand.
• Experience with Argo Workflows.
• Experience with hybrid storage and data transfer: NetApp ONTAP, AWS DataSync, rclone.
• Experience in pharma, life sciences, or other regulated industries.
• AWS certifications.

We offer:

• Competitive compensation
• Remote or office work
• Flexible working hours
• Healthcare benefits: medical insurance and paid sick leave
• Continuous education, mentoring, and professional development programs
• A team with an excellent tech expertise
• Certifications paid by the company
