Enterprises, when starting on their modernisation journey, often imagine that they will simplify their environment. The reality for many, however, is that adoption of technologies such as cloud adds additional technologies and capabilities, drives divergence in operating models, often splits business processes across multiple tech stacks in different landing zones and, overall, adds significant complexity to the enterprise estate.

You must help make sense of this new complexity, and be able to tame it through judicious use of both old and new technologies coupled with “hybrid” processes that address the needs of both the legacy and the new platform environments. You will have knowledge of both the traditional enterprise landscape, as well as an appreciation of the major cloud platforms and the opportunities, capabilities and pitfalls they present. You will be responsible for helping KPMG to clarify client problems and assist the development of logical and implementable solutions to those problems through robust analysis.
