Data Integration Lead

Sizewell C’s business is to design, finance, construct, commission, operate, maintain, and eventually decommission the nuclear power plant and related infrastructure at Sizewell C in Suffolk. Overall, whilst the Company is in the construction phase, the Boards’ principal focus is on the development and construction of Sizewell C on time, on budget and to the highest quality and safety standards. The Company is maturing to meet all these requirements.

Sizewell C is economically regulated by OFGEM under the Regulated Asset Base (RAB) model similar to other UK electricity distribution networks and Thames Tideway.

Sizewell C construction strategy is to replicate the design of Hinkley Point C, using the majority of the same supply chain, but innovating in the way it is delivered to achieve savings in time and cost of around 20%. The CCO will need to be guided by and incorporate lessons learned from the Hinkley Point C commercial delivery to achieve Sizewell C’s ambition.

Following Financial Completion and Revenue Commencement, Sizewell C is fully funded and is owned by; The Secretary of State for Energy Security and Net Zero representing HM Government, La Caisse, Centrica, EDF and Amber Infrastructure.

Sizewell C is entering an exciting phase of growth as we mature into an independent organisation and continue building one of the UK’s largest and most important energy projects. We are now recruiting the below position.

Impact:

As Data Integration Lead, you will own and govern the existing integration strategy, standards and patterns for SZC and our supply chain, ensuring that the integrations we build and operate are API led, efficient, robust and secure. You will work closely with business stakeholders, solution architects, data architects, cyber security, service management, suppliers and the ICoE to translate business requirements into clear integration specifications, technically assure delivered integrations, prioritise new integration requests and ensure integrations are reusable, secure, supportable and future-proof.

As part of your role, you will deliver:

Integration Strategy & Standards

• Own, maintain and evolve SZC’s existing API-led integration strategy, standards, principles and reusable integration patterns.
• Apply SZC integration patterns to determine the appropriate integration approach for each use case, including MuleSoft, SAP Integration Suite/BTP, Azure Integration Services, native system integrations and zero-copy patterns.
• Document the rationale for integration pattern decisions, including business requirements, cost, architectural fit and operational support.
• Ensure integration solutions follow API-led, standards-based, secure, reusable and operationally supportable design principles.
• Promote reuse of existing APIs, services, patterns and integration components to reduce duplication, delivery cost and technical debt.
• Act as a neutral party, determining if digital integrations are appropriate when a business process change or a manual approach could yield better results more cost-effectively depending on the use case.
• Ensure new requests are independently assessed with the ICoE lead architect for adherence to the approved SZC integration strategy and for any deviations, agreed and captured with supporting rationale within the integration strategy

Integration Service & Delivery

• Oversee the Integration Centre of Excellence (ICoE) delivery lifecycle from early engagement through to requirements capture, estimation, design, build, test, production implementation and enduring support.
• Translate business and technical requirements into clear high-level integration specifications that can be worked up and then delivered by the ICoE, internal teams or suppliers.
• Review ICoE assumptions, dependencies, delivery plans and cost estimates to support integration funding approval.
• Provide independent technical review of Integration Specifications, supplier-built and ICoE-built integrations for quality, security, supportability, performance and architectural alignment before release.

Integration Catalogue & Planning

• Own and manage SZC’s integration catalogue, covering live, planned and proposed system-to-system and system-to-data platform integrations.
• Triage and prioritise new integration requests based on business value, urgency, architectural fit, approved pattern alignment, delivery complexity, security considerations, cost and capacity. This will include liaison with the ICoE lead architect
• Identify duplicate, overlapping or inconsistent integration requests and steer stakeholders towards reusable services or approved patterns.
• Track the integration pipeline, dependencies, risks, blockers and delivery progress across SZC and partner organisations.
• Work with the Architecture team to ensure all system integrations are modelled accurately in the Enteprise Architecture tooling

Integration Security & Governance

Ensure integration designs meet SZC security, access control, data pr
