Integration Engineer – IICS & Boomi

Integration Engineer

IICS and Boomi

Full-time | Chennai | On-site | Immediate Joiner | U.S Overlapping Hours

Role Overview

We are looking for an experienced Integration Engineer to join the data team on a strategic account with an enterprise manufacturing client, working alongside our Data Architect and the wider engineering, integration, and BI team. This is a permanent, full-lifecycle role: you will design, build, maintain, and optimize integration services on the client's Boomi and IICS platforms, working within their established enterprise architecture and governance standards.

A major current initiative is consolidating a legacy Talend estate into Boomi and IICS. You will help rebuild and rationalize those services onto the right target platform - reliably, with proven output parity - and contribute technical tool-fit input to the assessment framework that decides the best target (Boomi vs IICS) for each service. But the role extends well beyond migration: as the estate consolidates, you own the ongoing health of the integration landscape - new service design, enhancements, production support, and performance and cost optimization.

The core skill is depth in the target platforms - Boomi and IICS. Talend familiarity is a strong accelerator for the consolidation work, but not a prerequisite: you'll be reading Talend to understand intent, not building new Talend.

Key Responsibilities

Design and Build

• Design and implement integration services on Boomi and/or IICS, following the client's architecture standards and integration patterns.
• Build integration flows, mappings, orchestrations, connectors, error handling, and scheduling.
• Enhance and extend existing services as business needs evolve.
• Own solution design decisions and communicate their trade-offs to technical and business audiences.

Migration and Consolidation

Current initiative

• Rebuild legacy Talend integration services on Boomi and/or IICS.
• Reverse-engineer existing Talend jobs to establish their true behavior - business logic, transformations, edge cases, and data handling - not just their surface intent.
• Partner with the team's existing Talend knowledge holder to validate understanding of legacy services.
• Define and run parity / reconciliation testing to prove each rebuilt service matches its legacy output; resolve source-to-target discrepancies.
• Contribute technical tool-fit input to the Boomi-vs-IICS assessment framework.

Maintenance and Optimization

• Provide ongoing production support for built integration services - monitoring, troubleshooting, and resolving issues.
• Optimize services for performance, reliability, and cost / consumption efficiency.
• Perform root-cause analysis and implement sustainable fixes.
• Maintain a prioritized backlog of improvements and technical debt.

Collaboration and Delivery

• Work within the client's enterprise architecture, governance, and security standards.
• Coordinate with the Data Architect, platform, security, and business teams.
• Maintain clear documentation of services, designs, and support procedures.

Required Skills and Experience

• Demonstrated depth as an integration / ETL engineer across the full lifecycle - design, build, and ongoing maintenance (we are flexible on total years).
• Working knowledge of both Boomi and IICS, or a strong track record of ramping quickly onto an adjacent iPaaS platform.
• Strong integration fundamentals: mappings, transformations, orchestration, connectors, APIs, error handling, and scheduling.
• Experience maintaining and optimizing integration services in production - performance, reliability, and cost / consumption.
• Proven ability to reverse-engineer undocumented or lightly-documented integration jobs and rebuild them faithfully.
• Discipline around validation - reconciliation and parity testing to confirm rebuilt services match legacy behavior.
• Strong SQL.
• Comfortable working within, and delivering to, an established enterprise architecture and governance framework.
• Clear communicator - able to explain technical decisions to both technical and business audiences.

Preferred Skills

• Talend experience - even at a read / maintenance level - to accelerate reverse-engineering of the legacy estate.
• Strength in both Boomi and IICS.
• Experience with data platform migrations, consolidations, or replatforming.
• Familiarity with Snowflake and AWS data / platform services (the client's data estate sits on this stack).
• Data governance, security, and role-based access concepts.
• Experience delivering into a large, standards-driven enterprise - ideally in manufacturing or a comparable industrial / operational domain.
• Familiarity with ITIL-based incident, problem, and change-management processes.

Preferred Certifications

Certifications are a plus; hands-on capability matters more.

• Boomi certification (Associate / Professional Developer / Architect)
• Informatica Cloud (IICS) certification
