Senior Workday Payroll 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 payroll, time tracking, and absence are the workstreams where getting the details right matters most: every employee feels it on payday. We are hiring a Workday Payroll, Time tracking & Absence Lead to own these modules end to end, from implementation design through go-live and into steady-state operations. You will be our resident expert on how Workday calculates, accrues, and pays, for US employees running on Workday Payroll and for our international workforce running through Workday and our global payroll providers.

This is a hands-on configuration role for someone who knows Workday Payroll, Time Tracking, and Absence deeply, understands the compliance stakes across multiple jurisdictions, and is comfortable being the person People, Finance, and Payroll Operations call when a calculation looks wrong.
