Meta is now mandating top software engineers join its new Applied AI Engineering unit, abandoning voluntary sign-ups. This unit aims to develop AI agents capable of handling significant engineering tasks, reflecting a company-wide push towards AI integration. These compulsory transfers signal a major internal restructuring as Meta prioritizes AI development.
Meta has started compelling top software engineers from across the company to transfer into its new Applied AI Engineering (AAI) unit, dropping the pretence of voluntary sign-ups, according to an internal memo seen by Reuters.
The unit, led by Reality Labs VP Maher Saba, is tasked with building AI agents that can eventually handle much of Meta’s own engineering work—and the company wants its strongest talent staffing it, whether they like it or not.When Saba set up AAI in March, he put out an open call. Engineers could raise their hand if interested. That courtesy is now gone. His latest memo is blunt: the company has worked with leaders across Meta to handpick engineers for the transfer, and they don’t get to decline.“AAI is one of the company’s highest priorities and we’re resourcing it by moving our strongest talent to address it. Therefore, the transfers aren’t optional,” Saba wrote, responding to an employee who had evidently asked. Selected engineers are being notified this week.
The unit is designed to build the AI tools that will eventually do much of Meta’s own engineering work
AAI’s mandate is specific: build the tooling, evaluations, and data pipelines that help Meta’s AI agents write code, run tests, and ship products with minimal human involvement.
Saba has described a future where these agents handle the bulk of the company’s engineering output, with people overseeing rather than doing. Teams within the unit will run at ratios as high as 50 engineers per manager—a structure designed for speed, not hand-holding.The unit feeds directly into Meta Superintelligence Labs (MSL), the division former Scale AI chief Alexandr Wang has been building since last summer.
MSL released its first model, Muse Spark, earlier this month and is quietly assembling a dedicated hardware team, hiring veteran engineer Rui Xu—previously at ByteDance and Xiaomi—to lead it. Wang has promised more models are on the way, some open-source.
The forced transfers are part of a much larger reorg reshaping Meta from the inside
AAI isn’t happening in isolation. Meta cut roughly 700 jobs in late March across Reality Labs, recruiting, sales, and parts of Facebook, Reuters reported. Deeper layoffs are reportedly still ahead—potentially tens of thousands—as the company tries to offset massive AI infrastructure spending. Reality Labs has already restructured some teams into small “AI-native pods,” rebranding engineers as “AI builders” and setting explicit targets for AI-assisted code output.CEO Mark Zuckerberg told investors in January that 2026 would be the year AI “dramatically” changes how Meta works. The compulsory transfers suggest he meant it.
