Job description

Our mission is BUILDING COMMUNITIES. We've earned national recognition, including being named a Great Place to Work and consistently ranking on Engineering News Record's Top 500 Design Firms in the United States and we're still growing! HR Green is bringing its Workday integration portfolio in-house, and we are looking for a Senior Workday Integration Developer to own it. Our Workday environment connects HR, payroll, and finance data with key enterprise systems through custom Workday Studio integrations and packaged connectors. You will assume ownership of these integrations from our implementation partner, support them in production, adapt them as systems change, and build new integrations as our Workday capabilities expand.

This is a permanent, in-house, fully remote role within one of the states where we currently operate, including Arizona, California, Colorado, Florida, Illinois, Iowa, Minnesota, Missouri, South Dakota, Texas, not a project engagement. As the integration portfolio stabilizes, you will also become HR Green's technical resource for our firm-wide AI program: taking over AI agents and their supporting integrations built by external specialists, maintaining and adapting them, and building new ones, partnering with those specialists on larger implementations as the program grows. If you are a Workday integration developer who wants to own an environment end to end, establish long-term internal ownership, and grow into applied AI work with real business impact, keep reading.

Lead the transition of our Workday integrations from the implementation partner to internal ownership, including knowledge transfer, runbook and specification review, and setting up monitoring and support procedures

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

Plan and run integration regression testing for Workday releases and connected-system upgrades

Build new agents and automations, independently or with external specialists, and apply our standards for agent testing, monitoring, and lifecycle management

Apply secure development practices and follow HR Green change-management, source-control, and release processes; Bachelor's degree in Computer Science, Information Systems, or a related field, or equivalent experience

Five or more years developing and supporting system integrations, including three or more years building and supporting Workday integrations in production with hands-on Workday Studio development, and working familiarity with the broader Workday integration toolset (EIB, Core Connectors, Cloud Connect, Workday Web Services, Reports as a Service, XSLT)

Experience with taking ownership of integrations built by others and operated them reliably, including diagnosing failures across systems, root-cause analysis, and restoring service

Hands-on experience consuming REST and SOAP APIs, JSON and XML, and token-based and OAuth 2.0 authentication

Working proficiency in XML/XSLT and at least one general-purpose programming language, plus source control and code review

A candidate who can explain technical issues, risks, and trade-offs clearly to HR, Finance, and operations partners

Demonstrated aptitude and interest in applying AI and automation platforms to business problems

Experience building on LLM platforms or enterprise copilot/agent tooling is preferred

Experience integrating a professional-services ERP, payroll or benefits providers, identity directory, ITSM, or learning platforms is preferred

Proficiency in Python and working knowledge of SQL are preferred

Current or prior Workday integration certification or equivalent formal Workday Studio training, and cloud or AI certifications, are a plus

It's your chance to join one of the country's longest-operating engineering firms and a leader in local markets in design engineering and construction with over 700 employees in 19 offices around the nation.
