Workday Extend & Integration Engineer

Job Description: Workday Extend & Integration Engineer

Position Overview

The Workday Extend & Integration Engineer will design, develop, deploy, and maintain custom applications and enterprise integrations across our Workday HCM and Financial Management ecosystem.

In this role, you will leverage Workday Extend (App Builder, Page Builder, and Orchestration Builder) alongside core integration technologies (Workday Studio, EIBs, REST/SOAP APIs, and WQL) to deliver tailored user experiences, automate multi-system transactional workflows, and bridge custom business logic directly within the Workday user interface.

Key Responsibilities

1. Workday Extend Application Development

• Architect and implement custom applications within Workday using Workday App Builder / Page Builder, Presentation components, and custom business objects (MDS - Model Definition Service).
• Build synchronous and asynchronous transactional workflows using Orchestration Builder (Workday Orchestrate) to connect UI events to backend services.
• Extend core HCM and Financial data structures with custom objects, fields, and relationships while safeguarding data integrity.
• Configure security policies, domain restrictions, and role-based permissions specific to Extend apps and custom data objects.

2. Enterprise Integrations & Orchestration

• Develop, monitor, and optimize complex inbound and outbound integrations using Workday Studio, Enterprise Interface Builder (EIB), Core Connectors, and Document Transformation (XSLT).
• Utilize Workday Query Language (WQL) and Workday REST / SOAP APIs for efficient, targeted data extraction and real-time synchronization.
• Connect Workday seamlessly with third-party enterprise platforms (e.g., banking/payment gateways, ERPs, procurement systems, CRM, and cloud data warehouses).
• Determine architectural boundaries between Orchestrations (lightweight, real-time UI/API workflows) and Workday Studio (heavy data transformations, large batch processing, and complex error handling).

3. Maintenance, Governance & Release Support

• Manage end-to-end SDLC processes, tenant migrations, and deployments using Workday Object Transporter (WOT) or Solutions packaging.
• Perform impact analysis, regression testing, and remediation for Workday’s semi-annual feature releases (R1/R2) across custom Extend apps and integrations.
• Troubleshoot runtime errors, log diagnostics, memory/payload limitations, and API rate limits.
• Maintain comprehensive technical design documentation, interface control documents (ICDs), and architecture runbooks.
