Anthropic Hires Workday CTO to Build AI-Powered HR Software

Anthropic has brought on Peter Bailis, who recently served as chief technology officer at Workday, to work on reinforcement learning engineering. Bailis will focus on making the startup's AI systems run faster and more reliably.

Bailis spent only weeks at Workday before leaving for Anthropic. The move signals the company's intention to build its own HR applications-software that handles hiring, employee training, development, and promotions.

Why Anthropic Is Moving Into HR Software

Anthropic posted a job opening for an engineering manager to oversee development of what it called "people products." The company specifically sought candidates with experience at Workday, Salesforce, and NetSuite, three major enterprise software providers.

The hiring reflects a broader shift in how AI companies operate. Rather than focusing solely on building foundational models, firms like Anthropic are now competing directly with traditional software makers by applying AI to specific business problems.

Bailis' Background

Bailis earned a bachelor's degree in computer science from Harvard University and a PhD in computer science from UC Berkeley in 2015. His doctoral work focused on data systems and large-scale computing.

Before joining Workday, he was an assistant professor at Stanford University researching data systems. He founded Sisu Data, a company focused on data analytics, and served as vice president of engineering for AI at Google Cloud.

What This Means for HR Professionals

AI for Human Resources is no longer a future concern-it's shaping how major technology companies compete for talent and build products. As AI firms move into HR software, HR leaders should understand how these tools differ from traditional enterprise platforms.

For HR executives overseeing digital transformation, an AI learning path for CHROs provides practical knowledge on AI applications in recruitment, workforce analytics, and talent management.

Workday's Response

Workday promoted Gabe Monroy, a senior vice president who joined from Google Cloud last August, to replace Bailis as CTO. The move keeps the company's leadership focused on AI and data infrastructure amid increased competition from startups.
