Integration Engineer, IICS & Boomi

Role Overview

We are looking for an experienced Integration Engineer to join the data team on a strategic account with an enterprise manufacturing client. This is a permanent, full-lifecycle role where 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 involves consolidating a legacy Talend estate into Boomi and IICS. You will help rebuild and rationalize those services onto the right target platform, contributing technical tool-fit input to the assessment framework that decides the best target (Boomi vs IICS) for each service. The role extends beyond migration to encompass ongoing health of the integration landscape, including new service design, enhancements, production support, and performance and cost optimization.

Key Responsibilities

• Design and Build
• Design and implement integration services on Boomi and/or IICS, following client 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
• Rebuild legacy Talend integration services on Boomi and/or IICS.
• Reverse-engineer existing Talend jobs to establish their true behavior, including business logic, transformations, edge cases, and data handling.
• 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 integration services, including 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.

Requirements & Tech Stack

• Demonstrated depth as an integration / ETL engineer across the full lifecycle: design, build, and ongoing maintenance.
• 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 for 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).
• Strength in both Boomi and IICS.
• Experience with data platform migrations, consolidations, or replatforming.
• Familiarity with Snowflake and AWS data / platform services.
• Data governance, security, and role-based access concepts.
• Experience delivering into a large, standards-driven enterprise.
• Familiarity with ITIL-based incident, problem, and change-management processes.

Preferred Certifications

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