Job Description

Positron AI is seeking a Senior or Principal Infrastructure Security Engineer to secure and manage the transition from on-prem systems to a hybrid-cloud environment on GCP. This role focuses on identity and access controls, secure developer infrastructure, secrets and artifact protection, and detection and response capabilities for critical systems.

Identity Platform and Access Control

Define, implement, and operate the identity platform, including Auth0 and role-based access control (RBAC) across internal systems and cloud environments.
Establish least-privilege access policies and lifecycle processes for users, service accounts, and machine identities.

PKI and Certificate Lifecycle

Design and manage public key infrastructure (PKI), including certificate issuance, rotation, and revocation.

Hybrid-Cloud Migration and Secure Infrastructure

Lead the migration of on-prem workloads to a secure hybrid-cloud environment on GCP.
Design and enforce network segmentation between on-prem, cloud, and critical infrastructure environments.
Build and maintain cloud infrastructure for developers using infrastructure as code with Terraform and Ansible.

Developer Tooling, Artifacts, and Secrets Management

Deploy and maintain artifact storage and other core developer tooling with security built in from the start.
Own secrets management across environments, ensuring credentials and keys are stored, accessed, and rotated safely.

Detection, SIEM, and Incident Response

Select, deploy, and operate a SIEM solution covering critical infrastructure.
Build and lead incident response processes, covering detection and triage through remediation and post-incident review.

Required Qualifications

Expertise in identity and access management, including SSO, RBAC, and identity platforms such as Auth0, Okta, or similar.
Experience with Kubernetes, including managed or proprietary Kubernetes distributions.
Hands-on experience building and managing infrastructure as code with Terraform and Ansible.
Production experience with GCP, or with Azure or AWS, with willingness to work in GCP.
Proven experience deploying, tuning, and operating a SIEM solution.
Experience with PKI, including certificate management and lifecycle automation.
Demonstrated incident response experience, including leading investigations and remediation.
Experience deploying and maintaining artifact storage and secrets management systems.
Understanding of network segmentation and secure network design across on-prem and cloud environments.

What Success Looks Like

Within the first three to six months, define and stand up the identity foundation with Auth0 and RBAC in place across key systems.
