About the Role

As Data Integration Lead, you will own and govern the existing integration strategy, standards, and patterns for SZC and its supply chain, ensuring that integrations are API-led, efficient, robust, and secure. You will translate business requirements into integration specifications, technically assure delivered integrations, prioritize new integration requests, and ensure integrations are reusable, secure, supportable, and future-proof.

Responsibilities

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.
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.
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 for delivery 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.
Own and manage SZC’s integration catalogue, covering live, planned, and proposed system-to-system and system-to-data platform integrations.
Triage and prioritize new integration requests based on business value, urgency, architectural fit, approved pattern alignment, delivery complexity, security considerations, cost, and capacity.
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 organizations.
Work with the Architecture team to ensure all system integrations are accurately modeled in the Enterprise Architecture tooling.
Ensure integration designs meet SZC security, access control, data protection, auditability, and operational support expectations.
Apply secure-by-design principles across APIs, data flows, credentials, certificates, secrets, access policies, integration runtimes, and monitoring.
Ensure integrations include appropriate monitoring, alerting, logging, and traceability before go-live.
Define and assure operational support requirements for all live integrations.
Ensure exceptions from approved integration patterns are documented, justified, and escalated through the appropriate governance route.
Act as the primary point of contact for integration requests, guidance, and prioritization across business and technology teams.
Communicate integration principles, decisions, and trade-offs clearly to technical and non-technical stakeholders.
Work with project managers, business analysts, architects, suppliers, and system owners to shape integration requirements early in the delivery lifecycle.
