- ERP Custom Enhancement: Create custom ABAP objects, User Exits, BADIs, and Enhancement Spots within core S/4HANA manufacturing modules (PP, QM, MM, PM) using RAP (ABAP RESTful Application Programming Model) or modern extensibility frameworks.
- 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 Consultant and Principal SAP MII/ME Architect to translate technical specifications into secure, scalable S/4HANA and BTP solutions.
Technical Qualifications- ABAP on ECC & S/4HANA migration Expertise: 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.

- Modern SAP Development Stack: Deep expertise in building CDS Views, OData services, AMDP, and applying SAP's "Clean Core" development principles.
- Manufacturing Module Knowledge: Deep technical understanding of the underlying database tables and logic inside S/4HANA PP (Production Planning), QM (Quality Management), and MM (Materials Management).
- Shop-Floor Context: Prior experience developing code specifically designed to interact with Manufacturing Execution Systems (MES) or SAP MII/ME layers (excluding SCADA).
Soft Skills & Compliance- Strong analytical skills with a precise attention to detail required for the highly regulated A&D industry.
- Collaborative mindset with the ability to work effectively across global, distributed technical teams.
- Due to ITAR regulations and defense contract restrictions, US Citizenship or specific regional security clearances may be required.
