Senior SAP BTP Full-Stack Developer (CAP Java & MDK)

Position Purpose

To design, develop, and maintain enterprise-grade applications on SAP Business

Technology Platform (BTP) using Cloud Application Programming Model (CAP) Java

for backend services and Mobile Development Kit (MDK) for cross-platform mobile

applications. The role involves architecting scalable, secure, and high-performance

solutions that integrate with SAP S/4HANA, SAP Analytics Cloud, and other

enterprise systems while ensuring seamless offline capabilities, robust data

synchronization, and exceptional user experience across web and mobile channels.

Key Responsibilities

Backend Development (CAP Java)

• Design and implement microservices using CAP Java with CDS modeling,

ensuring optimal performance, multi-tenancy support, and transactional

consistency

• Develop custom event handlers (@Before, @On, @After) with proper

transaction management and business logic implementation

• Create CDS views with calculated fields and aggregations for complex

reporting requirements

• Implement fine-grained authorization using @Restrict annotations, CDS

aspects, and custom authorization handlers

• Integrate external REST APIs using DestinationService with resilience

patterns (circuit breaker, bulkhead, rate limiting)

• Design and implement event-driven architectures with saga patterns for

distributed transaction management

• Optimize application performance through lazy bean initialization, query

optimization, and caching strategies (Spring Cache with Redis)

• Implement complex business workflows using Spring State Machine with

persistent state storage

Mobile Development (MDK)

• Develop cross-platform mobile applications using SAP Mobile Development

Kit (MDK) with offline-first architecture.

• Implement robust offline synchronization with optimistic locking, delta

synchronization, and conflict resolution strategies

• Create custom NativeScript plugins for native platform integration with proper

lifecycle management

• Design and implement complex validation frameworks with cross-entity

validation and shared context objects

• Build advanced UI components using MDK's metadata-driven approach with

custom formatters and extension controls

• Implement real-time data synchronization using SAP Mobile Services push

notifications and OData change tracking

• Develop complex action chains with conditional branching, parallel

processing, and persistent workflow state

• Integrate SAP Analytics Cloud for embedded analytics and reporting within

mobile applications

Architecture & Quality

• Define technical architecture for full-stack SAP BTP applications ensuring

scalability, security, and maintainability

• Establish coding standards, design patterns, and best practices for CAP Java

and MDK development

• Implement comprehensive testing strategies including unit tests (Jest),

integration tests (mock OData), and UI automation (Appium)

• Conduct code reviews and provide technical mentorship to junior developers
• Create technical documentation, architecture decision records, and API

specifications

• Collaborate with functional consultants to translate business requirements into

technical solutions

DevOps & Operations

• Set up CI/CD pipelines for automated build, test, and deployment of CAP and

MDK applications

• Monitor application performance and implement optimizations based on

metrics and user feedback
