Backend Developer - Integration & Data Services

SUMMARY
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.
