About the job:
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.
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.
- 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.
- Work within an Agile / Scrum squad, contributing to discovery workshops, design reviews and cross-squad integration alignment.
Tech Stack:
- Java, Spring Boot, Microservices, REST APIs, Informatica ETL, APIGEE, SQL, Elasticsearch, Git, CI/CD.
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.
- Hands-on Informatica ETL development including mappings, transformations and job orchestration.
- Solid SQL and data-modelling skills.
- 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.
Nice-to-have:
- Exposure to SAP (HANA, ECC) and SAP data-extraction tooling such as SLT or SAP adapters.
- Salesforce (SFDC) integration experience.
- Cloud platform experience, particularly Azure / Azure AD.
- 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.
