Remote Workday API Integration Engineer W2

ONLY W2

• W2 Contract, 6 Months

• Our client is seeking a Senior hands‑on Integration Engineer with deep Workday expertise and strong system‑agnostic integration and software engineering fundamentals.
• This role is responsible for designing, building, and troubleshooting API‑driven integrations between Workday and enterprise platforms. Workday serves as the system of record, while Microsoft Power Automate and other tools act as orchestration and execution layers.
• The ideal candidate possesses a deep mastery of Workday APIs, data structures, and business processes, complemented by a robust background in platform‑agnostic integration architecture and engineering principles.

• Workday REST APIs
• Workday SOAP APIs (Web Services)
• Workday data model and business process logic

• XML payloads and API requests
• API responses and error handling
• Authentication, security, and integration context

• Explicit validation prior to write‑back
• Deterministic execution and predictable outcomes
• Robust error handling and retry strategies
• Full observability including logging and audit trails

• Raw API request and response data
• Workday Business Process state and configuration
• Data integrity and sequencing issues across systems

• Power Automate
• API layers
• Workflow and automation platforms

• Workday enforces business rules and approval flows
• External systems orchestrate, not override system‑of‑record logic.

• 4+ years of hands‑on experience in Workday integration.
• Must demonstrate hands‑on Workday API experience and integration engineering depth.
• Strong proficiency in Workday SOAP APIs (Web Services), Workday REST APIs, and a deep understanding of the Workday data model and object relationships.
• Solid understanding of Workday Business Process‑controlled API behavior and the ability to construct API requests manually.
• Proven ability to troubleshoot failures at the request/response level and debug integrations without relying on Studio abstraction layers.
• Strong understanding of XML structure, name spaces, and schema validation.
• Comprehensive knowledge of integration security (ISU, ISSG), authentication, and API connectivity patterns.
• Demonstrated ability to design integrations that are deterministic, resilient, observable, and auditable.
• Strong understanding of core integration patterns, including API‑driven architecture, request/response vs. event‑driven models, and orchestration vs. system‑of‑record responsibility.
• Ability to define validation layers before system updates and design safe retry strategies that prevent data duplication or corruption.
• Proficiency in isolating failures across multi‑system workflows and experience working across multiple platforms beyond Workday.
• Strong analytical mindset with the ability to demonstrate software engineering fundamentals and solve complex integration challenges.
