The Role
As an Informatica IDMC Integration Developer, you will play a critical role in enabling seamless data and application integration across enterprise systems.
This role focuses on designing, developing, and supporting cloud‑based integrations using Informatica Intelligent Data Management Cloud (IDMC), with a strong emphasis on Cloud Data Integration (CDI) and Cloud Application Integration (CAI).
The role involves building and maintaining batch, real‑time, and event‑driven integrations, working with APIs and multiple data formats, and ensuring high standards of data quality, performance, and reliability. A strong focus is placed on error handling, monitoring, and optimization to ensure integrations run smoothly in production environments.

This position requires close collaboration with cross‑functional teams, including business stakeholders, architects, and downstream application teams, to understand integration needs and deliver end‑to‑end solutions. The developer is also expected to contribute to documentation, follow CI/CD and version control practices, and support integration deployments in a structured and controlled manner.

Please note US hours coverage required (1pm – 9pm GMT)

Your responsibilities:

• Develop and optimize integrations using IDMC CDI and CAI components.
• Work with JSON, XML, CSV, and other structured/unstructured data formats for ingestion, mapping, and transformation.
• Build reusable CDI mappings, mapping tasks, and parameterized pipelines optimized for performance and maintainability.
• Design and manage CAI processes, including service connectors, synchronous/asynchronous flows, event-driven integrations, and orchestration logic.
• Implement robust error‑handling frameworks, including retries, exception handling, boundary events, and comprehensive logging.
• Write and optimize SQL queries, stored procedures, and database scripts to support backend integrations.
• Monitor and tune IDMC workloads—task flows, schedules, secure agents, and job performance.
• Maintain strong data quality, resolve discrepancies through profiling, validation, and transformation rules.
• Collaborate with cross-functional teams to gather requirements and deliver high-quality integration solutions.
• Maintain up-to-date technical documentation, including design specifications and integration flow details.
• Support integration deployments using CI/CD pipelines, Git, and version control practices.

• Strong SQL skills: writing and optimizing queries, stored procedures, and scripts.
• Experience implementing error-handling mechanisms, including retries, exception handling, and logging.
• Ability to monitor and optimize task flows, schedules, and secure agents within IDMC.
