As Principal Engineer - Integration Services, you will establish and lead the Integration Services capability across Internal Products.

You will own the technical direction, engineering capability, people leadership, delivery and operational performance of shared integration and engineering services.

A key part of the role will be defining what should become a reusable Internal Products capability and what should remain owned within individual domains. You will establish common integration approaches, reusable services and engineering patterns that reduce duplication and make it easier for teams to connect systems safely and reliably.

You will provide senior technical leadership across major transformation programmes, including the Commercial Technology Programme, ensuring integration decisions made within individual programmes contribute to a coherent and sustainable technology estate.

You will also build and develop the team itself, establishing the engineering capability, operating model and ways of working required for a successful shared service organisation.

You are an experienced Principal Engineer or senior engineering leader with a strong background in enterprise integration, shared engineering services or platform capabilities.

You have experience working across multiple teams and technology domains, with the judgement to distinguish between capabilities that should be centrally owned and standardised and those that should remain within individual engineering teams.

You are comfortable operating at both strategic and technical levels. You can define a direction for shared integration and engineering capabilities while still engaging deeply enough with architecture, engineering practices, reliability and delivery to make credible technical decisions.

You are also an experienced people leader who can build and develop senior engineers and create a high-performing team around a new capability. You are able to influence teams without relying solely on formal authority and can establish common approaches where responsibilities have historically been distributed.

You understand that shared services succeed only when they are useful to the teams that depend on them. You therefore approach platform and integration engineering pragmatically, balancing standardisation and reuse with the needs of individual products and domains.
