You'll own the backbone of Onebrief’s COTS deployments: automate, secure, and scale the platform so product teams can move fast without breaking trust.
Building and automating the platform: Design, provision, and manage cloud and on‑prem environments with Terraform and Ansible; operate secure, resilient Kubernetes clusters for multi‑level deployments.
Designing and evolving CI/CD: Reduce lead time and maintain strict gates and environment parity by improving pipelines in GitLab CI/CD, Jenkins, and GitHub Actions.
