Senior SAP gATP/AATP Functional Architect - Remote

Here at RED, we are actively seeking a Senior SAP gATP/AATP Functional Architect to join our team for an S/4 HANA implementation project with one of our global end clients. The consultant is expected to commence in October 2026, with an initial six-month contract and the possibility of extension. This is a remote position with occasional travel required for workshops and go-lives.

Role Purpose

As a Senior Functional Architect, you will be a driving force in our migration to SAP S/4HANA, taking ownership of the functional design and architectural vision for order fulfillment and supply chain planning. You will serve as the primary subject matter expert (SME) on:

• Advanced Available-to-Promise (AATP)
• Product Allocation
• Alternative-Based Confirmation
• Advanced Intercompany scenarios

Qualifications

To succeed in this role, candidates should possess the following expertise and experience:

• gATP / AATP Expertise: Proven, deep functional and architectural experience in SAP gATP (APO) with a strong focus on S/4HANA Advanced Available-to-Promise (AATP). Experience with S/4HANA migrations is highly expected.
• Process Knowledge: Deep understanding of Sales & Distribution (SD) process flows and logistics integration points.
• Planning Background: Solid background in Supply Chain Planning concepts, including demand planning, supply planning, and capacity constraints.
• Niche Knowledge Areas: Demonstrated experience in configuring Alternative-Based Confirmation (ABC), Product Allocation & Rationing, Advanced Scheduling, and Advanced Intercompany (ICO).
• Technical/Development Acumen: While this is a functional architect role, a strong background in development/programming is required to effectively design solutions, read code, and guide ABAP/extensibility efforts.

Key Responsibilities

The key responsibilities of the Senior SAP gATP/AATP Functional Architect include:

• S/4HANA Migration & Architectural Leadership: Play a pivotal role in the transition from legacy SAP APO-gATP to SAP S/4HANA AATP, defining the target functional architecture and implementation roadmap.
• Solution Architecture: Act as the functional lead, prioritizing an "architectural vision" over hands-on coding to design robust, scalable, and future-proof order fulfillment processes.
• Custom Development Guidance: Utilize your strong technical/programming background to translate complex business needs into precise functional specifications. Collaborate closely with development teams on custom enhancements where standard logic is insufficient.
