Accountabilities
  • Lead and architect Java and Spring Boot solutions integrating SAP Ariba with backend enrichment, risk, and data services.

  • Establish and promote programming, configuration, security, and engineering best practices, including conducting code reviews and ensuring adherence to standards.
  • Lead and mentor engineers while fostering technical excellence, collaboration, and knowledge sharing.
  • Use AI-assisted development tools as part of the engineering workflow to improve productivity and accelerate delivery.
  • Support performance optimization, secure authentication, credential management, and reliable operation of third-party integrations.
Requirements
  • 8+ years of professional experience working with production Java applications, including strong hands-on experience with Spring Boot.
  • Deep practical expertise with SAP Ariba, particularly the Ariba Developer Portal, OAuth flows, API key and token management, Supplier Data API, and Cloud Integration Gateway.
  • Strong experience with SAP Ariba SIM/SLP configuration, including approval workflows, custom fields, risk modules, and understanding of platform limitations and common failure modes.
  • Proven experience building and maintaining backend integrations involving APIs, event-driven architectures, orchestration patterns such as AWS Step Functions, and NoSQL databases such as DynamoDB.
  • Working knowledge of SAP S/4HANA, Cloud for Credit, SAP Business Technology Platform (BTP), Cloud Application Programming Model (CAP), and SAP UI5.
  • Strong understanding of performance optimization and security best practices, particularly for third-party API authentication and credential management.
  • Proficiency with AI-assisted coding tools such as GitHub Copilot, Claude Code, or Cursor.
  • Experience working with Cloud Foundry is advantageous.
  • Experience with credit, financial, or other complex enterprise systems is a strong plus.
  • Demonstrated ability to lead complex software initiatives involving third-party SaaS or enterprise platform integrations.
  • Strong strategic thinking, decision-making, analytical, and problem-solving abilities.
  • Excellent communication and presentation skills, with the ability to explain complex technical concepts to diverse stakeholders.
