Job description

Role Purpose

As a hands-on Senior Platform Engineer - Lead, you will work within the Infra Delivery APAC team to transform from server-based infrastructure to a modern, AWS/Cloud-native platform. You will lead the design, build, secure, and operate cloud platforms and delivery pipelines; coach DevOps and infrastructure colleagues to uplift skills; and embed a disciplined plan‑build‑test‑release‑deploy‑monitor rhythm across teams. You are comfortable with frequent, incremental testing and deployments and champion a DevOps culture of automation, reliability, and continuous improvement.
