Senior Workday Integration Architect

Lambda, The Superintelligence Cloud, is a leader in AI cloud infrastructure serving tens of thousands of customers. Our customers range from AI researchers to enterprises and hyperscalers. Lambda's mission is to make compute as ubiquitous as electricity and give everyone the power of superintelligence. One person, one GPU.If you'd like to build the world's best AI cloud, join us.

* Note:

This position requires presence in our San Francisco or San Jose office location 4 days per week;
Lambda's designated work from home day is currently Tuesday.

Business Technology at Lambda builds and scales the internal systems that power our business. We partner across the company with Finance, GTM, Engineering, and People to implement tools, automate workflows, and ensure data flows securely and accurately. Our scope spans enterprise applications, integrations, data platform and analytics, compliance automation, and all things IT.

People Technology is the pillar that owns the systems every Lambda employee touches. We are in the middle of moving Lambda from Rippling to Workday as our HRIS, and integrations are the connective tissue that determines whether that move works. Every benefits enrollment, payroll file, new-hire provisioning event, and GL posting depends on data moving correctly between Workday and the rest of our stack.

We are hiring a Sr. Workday Integrations Architect to own the design, build, and operation of that integration landscape end to end, from implementation through go-live and into steady-state operations.

This is a hands-on architecture role for someone who is as comfortable building a Studio integration as they are defending a design decision in front of Security, Finance, and Audit. You will set the standards for how Workday talks to everything else at Lambda, and you will be the person People, Finance, IT, and Engineering call when data doesn't land where it should.

• 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 Net Suite, equity and compensation data, and other upstream systems) with clear data ownership and va
