To succeed, you will bring hands‑on experience in platform engineering or DevSecOps, with strong knowledge of cloud platforms, IaC, automation tooling, and secure development practices. You should be comfortable working across cross‑functional teams, contributing to continuous improvement, and supporting mission‑critical environments.
