• Collaborating with infrastructure, networking, and application teams to ensure security is embedded across operations
• Supporting after‑hours incident response on rotation as part of a 24/7 model
• Documenting processes, standard procedures, and learnings to strengthen how we operate long‑term

Requirements:
