About the role
Senior-level role owning the design, build, and operation of the Workday integration landscape end-to-end, including migration from Rippling, inbound/outbound integrations, data platform alignment, and SOX-compliant controls.
Responsibilities
- Integration Architecture: Define and own the target-state integration architecture for Workday: patterns, standards, naming conventions, error handling, monitoring, and reusable components. Decide when to use EIB, Core Connectors, Workday Studio, Web Services, RaaS, Workday Orchestrate, or Workato, and document why.
- Implementation: Serve as the technical lead for integrations in our Workday implementation. Drive design sessions, build and test alongside our implementation partner, review partner deliverables, and sign off on readiness for cutover, parallel testing, and hypercare.
- Rippling Migration & Data Conversion: Design and execute data extraction, transformation, and load from Rippling into Workday, including historical data, cutover sequencing, and validation. Own the plan to decommission Rippling-based integrations without gaps.
- Inbound Integrations: Build and maintain inbound feeds into Workday (recruiting and offer data from Ashby, org and cost center data from NetSuite, equity and compensation data, and other upstream systems) with clear data ownership and validation.
- Outbound Integrations: Build and maintain outbound feeds to benefits carriers, 401(k), tax filing, international and global payroll providers (PECI/PICOF or Global Payroll Connect), equity administration, and downstream consumers such as Okta, Lumos, and BigQuery.
- Finance & Payroll Integrations: Own payroll results, accounting journal, and GL posting integrations to NetSuite. Partner with Payroll Operations and Accounting on reconciliation so Workday, payroll provider results, and the general ledger stay in agreement.
- Identity & Provisioning: Partner with IT on the Workday-to-Okta lifecycle (joiner, mover, leaver), access provisioning through Lumos, and Workday security group and ISU/ISSG design for integration accounts.
- Data Platform & Reporting: Design Workday data extracts and RaaS reports that feed BigQuery and the analytics platform, and define data contracts so People Analytics and Finance can trust the numbers.
- Operations & Reliability: Establish monitoring, alerting, retry logic, runbooks, and on-call practices for integrations. Lead root-cause analysis when a file fails, a record is rejected, or a downstream system disagrees with Workday.
- Compliance & Controls: Design integrations and integration security to satisfy SOX ITGC requirements: least-privilege ISUs, credential and certificate management, change management, segregation of duties, audit trails, and evidence capture. Support internal and external audit requests.
- Releases & Roadmap: Stay current on Workday's semi-annual releases, assess impact on the integration footprint, run regression testing, and adopt new capabilities that reduce custom build and manual work.
- Enablement & Mentorship: Write the documentation, integration inventory, and data dictionaries. Mentor analysts and partner consultants, and set the bar for code review, testing, and design quality.
Qualifications
- 10+ years in HRIS, enterprise integration, or systems architecture, with at least 6+ years designing and building Workday integrations. You have taken at least one full Workday HCM implementation live as the integration lead or architect, including payroll and benefits integrations.
