Meta poaches senior engineer from Mira Murati’s Thinking Machines Lab as Silicon Valley talent war intensifies

What happened

A senior engineer who built Thinking Machines Lab’s flagship model Tinker from scratch has left the Mira Murati–founded startup to join Meta’s Superintelligence Labs, according to the engineer’s LinkedIn profile. The departure, first reported by IT Home and carried by ifeng (凤凰网), follows a string of high-profile exits as big tech aggressively recruits from the year‑old company.

It has been reported that Meta has now hired five founding members from Thinking Machines Lab, including co‑founder Andrew Tarlow, while OpenAI has reportedly brought in the lab’s former chief technology officer Barrett Zoph and cybersecurity expert Joline Parish. Who’s winning this war for engineers? The answer is messy and fluid.

Context and why it matters

Thinking Machines Lab, founded by former OpenAI CTO Mira Murati, has quickly become a talent magnet. It has been reported that the startup raised about $2 billion at a roughly $12 billion valuation last year and has grown to around 130 employees — up more than fourfold since launching. The firm has also recruited notable names reportedly including Soumith Chintala, the lead behind the PyTorch project, and competitive programming champion Neal Wu, according to Business Insider.

These moves matter beyond HR spreadsheets. They underscore how concentrated leading AI talent remains in Silicon Valley and how fiercely Western tech firms are competing for top researchers and engineers — even as broader geopolitical pressures, export controls and scrutiny of China‑linked tech ties reshape where and how advanced AI work can be deployed. The churn raises a simple question: can startups retain the people who make them valuable once the deep pockets and established platforms come calling?
