Minimum:

Work Experience

• Minimum of 3 years of experience in system integration, software development, or a similar role.

• System Integration Design and Development:

  • Designing Integration Solutions: Develop integration solutions that ensure different applications and systems can exchange data effectively. This can include systems like ERP, CRM, HRMS, and other enterprise applications.
  • Building Interfaces: Create interfaces between different systems using middleware technologies or APIs, enabling data flow between disparate applications and platforms.
  • Developing APIs: Design and build RESTful APIs, SOAP web services, and other integration components to expose data and functionality for internal or external systems.
  • Working with Integration Tools: Leverage integration platforms such as MuleSoft, Dell Boomi, Apache Camel, Tibco, or Oracle SOA Suite to implement integration solutions.

• Data Transformation and Mapping:

  • Data Transformation: Write code to transform data from one format (e.g., JSON, XML) into another to ensure compatibility between systems. This includes extracting, transforming, and loading (ETL) data from source systems to target systems.
  • Data Mapping: Define and implement data mapping rules to ensure data from one system can be accurately understood and processed by another.

• Middleware Configuration:

  • Middleware Management: Configure and manage middleware solutions that connect and mediate communication between various systems. Middleware includes tools like Enterprise Service Buses (ESBs), message queues, or integration platforms.
  • Monitoring Middleware and APIs: Ensure the stability, reliability, and performance of middleware components by setting up logging, monitoring, and alerting systems.

• API Integration:

  • Designing API Endpoints: Create and document RESTful APIs and SOAP services to integrate systems. Ensure that APIs are secure, scalable, and optimized for performance.
  • API Security: Implement proper security protocols, such as OAuth, API keys, and encryption, to protect data being transmitted through APIs.
  • API Versioning: Manage API versions and ensure backward compatibility when new versions of an API are released.

• Error Handling and Troubleshooting:

  • Error Detection: Implement error handling and logging mechanisms to detect, track, and report issues in the integration process.
  • Debugging and Issue Resolution: Troubleshoot integration failures, performance issues, and data discrepancies, working closely with other IT teams to resolve them.

• Testing and Quality Assurance:

  • Unit and Integration Testing: Write and execute tests to validate integration logic, ensuring data is correctly transformed, mapped, and transferred between systems.
  • Testing Environments: Set up and maintain development and test environments to simulate integrations and ensure that the solutions work as expected before deployment.

• Collaboration with Cross-Functional Teams:

  • Working with Business Analysts: Collaborate with business analysts to understand integration requirements and ensure that the integration solution addresses business needs.
  • Collaboration with Backend/Frontend Developers: Work with other development teams to ensure that integrations are implemented smoothly and meet both technical and functional requirements.
  • Stakeholder Communication: Liaise with stakeholders from other teams, such as operations, infrastructure, and support, to ensure that integration solutions meet the company's overall objectives.

• Performance Optimization:

  • Optimizing Data Flow: Continuously monitor and optimize integration solutions for performance, scalability, and efficiency, especially when dealing with high volumes of data.
  • Load Balancing: Implement load balancing strategies and optimize systems to ensure high availability and responsiveness of integration services.

• Documentation and Maintenance:

  • Documentation: Document the architecture, design, and implementation of integration solutions, as well as provide user guides and system specifications.
  • Version Control: Use version control systems such as Git to manage and track changes to integration code.
  • Maintenance and Updates: Regularly maintain and update integrations to accommodate new features, address issues, and ensure ongoing compatibility with other systems.

Desired candidate profile

• Programming Languages:

  • Proficiency in programming languages such as Java, C#, Python, JavaScript, Node.js, or SQL.
