Senior SAP AI Architect — BRFplus, ABAP & AI Agents

HM Revenue & Customs; United Kingdom; On-site; GBP 90,000 - 140,000; Full time

Job summary

HM Revenue & Customs is seeking a Senior SAP Decision & AI Architect to own the enterprise-platform projection of the prototype. You will map SAP-aligned decisions, integration patterns and test artefacts, exploring SAP-native AI/agent approaches where appropriate.

Responsibilities include designing BRFplus functions, data objects, rulesets and integration patterns, plus working with ABAP, APIs and BTP components across the landscape. You will guide when standard vs custom developments are best.

Qualifications

• Deep SAP solution architecture/delivery experience in complex enterprise landscapes.
• Hands-on BRFplus and ABAP experience and strong knowledge of SAP integration/API patterns.
• Experience in SAP TRM and/or PSCD/FI-CA or closely comparable rules-intensive SAP domains.
• Ability to consume recognized models/contracts created outside SAP rather than making SAP the source of domain semantics.
• Strong testing, transport, security, audit and operational-assurance discipline.

Responsibilities

• Map approved established concepts and deterministic rules into SAP-aligned designs without changing their upstream semantics.
• Design and prototype BRFplus functions, data objects, rulesets, decision tables and related integration patterns.
• Work across SAP TRM and/or PSCD/FI-CA, ABAP, APIs and BTP integration components as relevant to the target landscape.
• Prototype SAP-native AI/agent patterns, including Joule Studio experience, while keeping deterministic decision logic separately testable.
• Define mappings between standard identifiers and SAP objects/configuration so end-to-end provenance can be demonstrated.
• Design component, integration and regression tests, error handling, logging and operational controls.
• Advise when standard capability, configuration, extension or custom development is the appropriate implementation choice.
