SAP Security & Implementation Engineer £700 per day | Hybrid | Contract | Inside IR35 This isn’t a “keep the lights on” SAP role. You’re stepping into a live S/4HANA programme where security still needs shaping properly, not just maintained. The environment is complex, high-risk, and very real.

There’s still space to shape things properly, and your work will actually stick. It’s a live programme, still evolving, where security isn’t an afterthought, and your input will genuinely influence how it’s built.
