Workday Extend Developer

About this role

Workday Extend Developer1

Key Responsibilities

• Application Development & Architecture
• Custom App Design: Design and build end-to-end custom applications using Workday App Builder. Define app components including Pages, Business Objects, and Security domains.
• Logic & Orchestration: Develop complex Orchestrations (server-side logic) to handle business rules, ensuring data integrity and proper workflow execution (e.g., "If user clicks X, call external API Y, then update Workday Record Z").
• API Integration: Create robust integrations within Extend apps that consume REST/SOAP APIs from third-party vendors (e.g., integrating a badge scanning system, vaccination database, or external rewards platform directly into Workday).
• Data Modeling: Architect custom Business Objects inside Workday to store unique data fields that do not exist in the standard Workday data model.
• UX/UI Design: Design intuitive user interfaces using Workday’s Canvas Design System to ensure custom apps look and feel exactly like native Workday functionality.
• L2 Support & Operational Management
• App Maintenance & Monitoring: Monitor the health of deployed Extend apps using the Developer Site console. Troubleshoot runtime errors in Orchestrations or API failures (e.g., resolving "400 Bad Request" errors from external endpoints).
• Version Management: Perform impact analysis and code updates when Workday deprecates underlying APIs. Ensure custom apps are updated to the latest API versions (e.g., v39 to v40) to prevent breakage during bi-annual releases.
• Security Governance: Manage Security Groups and Domains specific to Extend Apps. Investigate "Access Denied" tickets where users cannot see specific custom pages or data elements.
• Performance Tuning: Optimize slow-loading apps by refining WQL (Workday Query Language) queries and reducing excessive API calls.
• CI/CD & Promotion: Manage the lifecycle of moving apps from Sandbox to Production, ensuring proper version control and testing evidence is documented.

Qualifications

• Mandatory Education & Certifications
• Workday Certification: Active Workday Extend certification is strictly required.
• Additional Certifications: Workday Integrations Core or Workday Studio certifications are highly preferred.
• Education: Bachelor’s degree in Computer Science, Software Engineering, or related technical field.
• Required Experience
• Workday Experience: 3+ years of technical Workday experience (Integrations or Extend).
• Programming Proficiency: Proven experience with standard web development concepts: JSON, REST APIs, JavaScript, or Python. (Note: This role requires actual coding logic, not just configuration).
• Data

Skills

• Proficiency in WQL (Workday Query Language) and relational database concepts.
• Security Standards: Understanding of OAuth 2.0, ISUs (Integration System Users), and ISSGs (Integration System Security Groups).

Preferred Skills

• Experience with serverless computing (e.g., AWS Lambda, Azure Functions) used in conjunction with Workday Extend.
• Knowledge of Workday Prism Analytics (using Prism datasets as a high-volume backend for Extend apps).
• This Job Description is tailored for a UiPath RPA Developer.

This role requires a blend of technical coding skills (.NET/C#), process logic (flowcharting/diagramming), and operational management (Orchestrator). I have structured this to include both the "Build" (Development) and "Run" (Support) aspects.
