• Performance Tuning: Troubleshoot, profile, and optimize complex ABAP code and S/4HANA database queries to handle high-volume, real-time data transmissions without latency.
• A&D Regulatory Adherence: Ensure all custom code, BTP applications, and data structures strictly comply with defense-specific compliance mandates, including ITAR data segregation and secure cloud standards.
• Technical Collaboration: Partner closely with the Lead Functional Consultants to translate technical specifications into secure, scalable S/4HANA ABAP and BTP solutions.

Qualifications

• 8-12+ years of advanced SAP ABAP programming experience, with minimum 1-2 projects (3+ years) of hands-on experience migrating & developing natively inside an SAP S/4HANA environment.
• Practical experience with SAP BTP services (such as SAP Integration Suite, Extension Suite, or BTP ABAP Environment) to develop side-by-side or decoupled extensions.
• Deep expertise in building CDS Views, OData services, AMDP, and applying SAP's "Clean Core" development principles.
• Deep technical understanding of the underlying database tables and logic inside S/4HANA PP (Production Planning), QM (Quality Management), and MM (Materials Management).
• "NICE TO HAVE" shop-floor prior experience developing code specifically designed to interact with Manufacturing Execution Systems (MES) or SAP MII/ME layers (excluding SCADA).

Requirements

• At least 2-3 Brownfield Implementations to S/4 HANA.
• Hands-on ABAP skills and hands-on remediation code work.
• Leadership skills and ability to deal with a strong personality who is the customer.

• 10-15+ years’ experience in SAP.
