Integration Engineer – IICS & Boomi

Full Time | Chennai

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 recent Talend.

Key Responsibilities:

Design & 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 & 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 & 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 & 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 - see note above).





· Working knowledge of both Boomi and IICS, with genuine working knowledge of the other - 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.

Certifications (a plus - hands-on capability matters more):

· Boomi certification (Associate / Professional Developer / Architect)

· Informatica Cloud (IICS) certification
