Backend Developer - Integration & Data Services

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.

•     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.

•     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.

•     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.

•     Bachelor’s degree in Computer Science, Engineering or equivalent practical experience.

•     5-10 years of experience in backend / integration development.
