Senior SRE/DevOps

Project description

We are looking for a Senior Platform / SRE Engineer who brings strong real‑world engineering experience, understands how to operate high‑availability (4‑nines) business‑critical systems, and can drive best‑practice engineering across the team.
You will design, build, optimise, and support reliable, scalable platform components, working closely with engineering teams to ensure smooth delivery, observability, and robust production readiness.
You provide pragmatic technical leadership, suggest improvements based on experience, and always prioritise quality, maintainability, and automation — aligned with enterprise‑grade standards used company-wide.
