Backend Developer - Integration & Data Services

About The Role

We are building a modern React-on-AEM B2B customer portal backed by SAP. This role sits in the integration and data-services team responsible for moving data from SAP into the portal's read layer and exposing it through secure, performant APIs. You'll work across the full path - moving and shaping data with Informatica ETL Pipelines, exposing it through well-designed microservices, and managing and securing those APIs at scale with Apigee. This role sits at the centre of our data-to-consumer flow, so you'll partner closely with data engineering, platform, and product teams.

Key responsibilities

• Design, build and maintain Java Spring Boot microservices that expose SAP-sourced data to the portal as clean, performant REST APIs.
• Develop and optimize Informatica data integration pipelines - ETL/ELT mappings, workflows, and transformations - to feed downstream services and analytics ( from SAP HANA into Elastic, reusing and extending existing HANA→Elastic job designs)
• Build configure and manage APIGEE API proxies - routing, security/OAuth, traffic management, rate limiting, caching, quota management, and error handling.
• Implement API productization on Apigee : developer portal setup, versioning, and consumption analytics.
• Ensure services are production-grade - instrumented for logging, monitoring, and alerting, with attention to latency, throughput, and resilience.
• Write clean, testable code with unit and integration test coverage, and participate in code reviews.
• Collaborate on API contract design and maintain clear technical documentation.
• Troubleshoot and resolve issues across the integration chain - from source data through the pipeline to the API gateway.
• Work within an Agile / Scrum squad, contributing to discovery workshops, design reviews and cross-squad integration alignment.
  
  

Must-have Skills & Experience

• Strong Java and Spring Boot with hands-on microservices / REST API development.
• Practical experience with APIGEE - building API proxies and configuring policies (security, OAuth, quotas, transformation).
• Hands-on Informatica ETL development including mappings, transformations and job orchestration.
• Solid SQL and data-modelling skills- comfortable working against enterprise databases.
• Experience integrating with Elasticsearch / Elastic as a data or search layer.
• Familiarity with CI/CD, Git and Agile delivery.
• Sound grasp of API security, performance tuning and troubleshooting in a multi-tier integration landscape.
  
  

Nice-to-have

• Exposure to SAP (HANA, ECC) and SAP data-extraction tooling such as SLT or SAP adapters.
• Salesforce (SFDC) integration experience (e.g. Web2Case, REST integrations).
• Cloud platform experience, particularly Azure / Azure AD for identity and hosting.
• Experience supporting a headless / decoupled front-end (React, AEM) via backend-for-frontend APIs.
• Background in B2B / order-to-cash or supply-chain domains.
  
  

Qualifications

• Bachelor's degree in Computer Science, Engineering or equivalent practical experience.
• 5-10 years of experience in backend / integration development.
