Senior Workday Integration Developer
About The Position
HR Green is bringing its Workday integration portfolio in-house and seeks a Senior Workday Integration Developer to take end-to-end ownership of the environment. The role will transition integrations from an implementation partner, support them in production, adapt them as connected systems change, and develop new integrations as Workday capabilities expand. The position is permanent, in-house, and fully remote within states where HR Green operates: Arizona, California, Colorado, Florida, Illinois, Iowa, Minnesota, Missouri, South Dakota, and Texas. It is not a project engagement. As the integration portfolio stabilizes, the developer will also become HR Green’s technical resource for its firm-wide AI program. This includes taking over AI agents and supporting integrations developed by external specialists, maintaining and adapting them, creating new agents, and partnering with specialists on larger implementations. The AI work focuses on secure, useful business solutions rather than AI research or model development. The role supports HR, payroll, and finance data connections with enterprise systems through custom Workday Studio integrations and packaged connectors. The developer will establish internal ownership, reliable operational support, and secure, maintainable integration and AI development practices.
Requirements
- Bachelor’s degree in Computer Science, Information Systems, or a related field, or equivalent experience.
- Five or more years developing and supporting system integrations.
- Three or more years building and supporting Workday integrations in production, including hands-on Workday Studio development.
- Working familiarity with EIB, Core Connectors, Cloud Connect, Workday Web Services, Reports as a Service, and XSLT.
- Experience taking ownership of integrations built by others and operating them reliably, including diagnosing cross-system failures, performing root-cause analysis, and restoring service.
- Hands-on experience consuming REST and SOAP APIs; working with JSON and XML; and using token-based and OAuth 2.0 authentication.
- Working proficiency in XML/XSLT and at least one general-purpose programming language.
- Experience with source control and code review.
- Ability to clearly explain technical issues, risks, and trade-offs to HR, Finance, and operations partners.
- Demonstrated aptitude and interest in applying AI and automation platforms to business problems.
- Some after-hours work is expected to support payroll-sensitive integrations.
Nice To Haves
- Experience building on LLM platforms or enterprise copilot/agent tooling.
- Experience integrating a professional-services ERP, payroll or benefits providers, an identity directory, ITSM, or learning platforms.
- Proficiency in Python and working knowledge of SQL.
- Current or prior Workday integration certification or equivalent formal Workday Studio training.
- Cloud or AI certifications.
Responsibilities
- Lead the transition of Workday integrations from the implementation partner to internal ownership, including knowledge transfer, runbook and specification review, and establishing monitoring and support procedures.
- Provide primary production support for integrations, prioritizing payroll-impacting feeds, and maintain the integration inventory and documentation.
- Design, build, test, and deploy new and modified integrations using Workday Studio, EIB, Core Connectors, Cloud Connect, Workday Web Services, Reports as a Service, and XSLT, including Studio integrations that call connected systems’ REST APIs.
- Improve error handling, batch tracking, logging, and notifications so failures are detected before affecting payroll or onboarding.
- Plan and conduct integration regression testing for Workday releases and connected-system upgrades.
- Take over, maintain, and adapt AI agents and their supporting integrations; define acceptance criteria for maintainable third-party deliverables; and build secure API connectors and service identities for approved agents to access HR Green systems.
- Build new agents and automations independently or with external specialists, applying standards for agent testing, monitoring, and lifecycle management.
- Apply secure development practices and follow HR Green change-management, source-control, and release processes.
- Perform other duties as assigned.
Benefits
- Comprehensive and multi-faceted benefits package; detailed total rewards information is available on the company website.
- Eligibility to participate in performance and discretionary incentive bonus programs after a qualifying period.
