Security Journey is hiring a Senior Platform Engineer to help scale and operate the platform behind our secure coding training products used by engineering organizations worldwide.
This is a hands-on role for an engineer who enjoys owning production systems, improving developer experience, and bringing order to fast-moving environments. You’ll help run the daily platform operation while driving long-term improvements in reliability, standardization, automation, and cost efficiency. We are a remote-first company with an office in Apex, NC for optional in-person collaboration.

  • Build internal self-service tooling and engineering guardrails that help developers ship safely and independently.
  • Improve CI/CD workflows using GitHub Actions and GitOps practices with ArgoCD.
  • Drive observability improvements using DataDog, including dashboards, alerting, and incident response readiness.
  • Partner with software engineers, QA, product, and security teams to remove friction and increase delivery velocity.
  • Lead infrastructure changes end-to-end using Terraform and modern IaC practices.
  • Reduce operational toil through automation, standardization, and thoughtful platform design.
  • Participate in an on-call rotation focused on ownership, reliability, and continuous improvement.
