The Opportunity

In Business Consulting, we deliver long-term value to our clients by transforming businesses through the power of exceptional insights, talent and experiences. This opportunity sits within the Business Transformation competency, a multidisciplinary team that helps design and deliver high-impact transformation programmes.

This role provides exposure to a range of industries, with a strong opportunity to contribute to work in the telecommunications sector. You will support organisations as they respond to technological disruption and operating model change, working across strategy, process design and enterprise architecture to deliver tangible business outcomes.

As a Senior Associate, you will support project delivery alongside experienced team members, contributing to business transformation initiatives. The role is well suited to candidates with a foundation in enterprise architecture, business analysis and process design, looking to grow their experience in complex, large-scale transformation environments.

Role Description

As a Senior Associate, you will play a hands-on role in supporting architecture-led transformation initiatives. The role focuses on developing enterprise and solution architecture deliverables, as well as process design artefacts, under the guidance of senior team members.

You will work closely with business and technology stakeholders to understand requirements, analyse current-state processes, and contribute to the design of future-state solutions. This includes translating business needs into structured outputs such as process models, architecture diagrams and supporting documentation.

You will contribute to the development of target operating models, enterprise architecture views and end-to-end business processes, aligned to recognised frameworks and EY’s Transformation approach. As part of multidisciplinary teams, you will support clients in improving processes, enhancing system integration, and enabling scalable digital capabilities.
