Tesla Starts Hiring for 'Terafab' AI Chip Factory

A few days after Elon Musk teased the official launch of the "Terafab" project, Tesla began recruiting the specialized talent required to build a semiconductor factory from the ground up.

The hiring push was first noted by X user @TeslaRyanRogue, who pointed to a new listing for a Technical Program Manager in Infrastructure Semiconductors based in Austin, Texas, indicating the effort has moved from concept to high-tech construction.

Why Tesla is building its own chips

Over the past decade, Tesla has pursued vertical integration, but computer chips have remained one of the few critical components it outsourced. As the company shifts from solely a carmaker to an AI and robotics enterprise, that reliance has become a major risk. Musk has identified chip supply as the next significant bottleneck, particularly as Tesla prepares to mass-produce the Cybercab robotaxi and the Optimus humanoid robot.

The job description underscores the scope of the program, seeking someone to "own end-to-end program scoping — including factory design/construction from concept through execution, ramp-up, and production readiness." Building a chip fab is among the most difficult manufacturing undertakings. Site selection is crucial because these plants depend on extremely precise lithography; even small vibrations from a nearby highway can spoil a production run. By bringing this in-house in Austin, Tesla aims to do for silicon what it did for battery cells.

Tesla silicon roadmap

Tesla’s AI chips are the computational backbone of its ecosystem. Today, the company relies on Samsung to manufacture its AI4 chips, which power the Full Self-Driving (FSD) system in mainstream vehicles. The upcoming AI5 chip is already designed and will be built jointly by TSMC and Samsung, with mass production targeted for mid-2027 and a generational leap in performance.

Looking ahead, Tesla has signed a huge deal with Samsung to produce AI6 in U.S.-based fabs. The Terafab is the "endgame." It would enable Tesla to iterate future chip designs at its own pace. Musk has also suggested that the AI7 chip and beyond could eventually be deployed in orbital data centers in space, working alongside SpaceX and xAI.

Ramping Up the "Machine that Builds the Machine"

Standing up a fab requires assembling the equipment and expertise for processes such as lithography, etching, and deposition under one roof. Tesla is seeking leaders with experience managing over $100 million in capital expenditures to oversee everything from utility planning to "tool installation" and "production qualification."

While Tesla expects to continue working with TSMC and Samsung for the next few years, the Terafab is intended to bring more of the AI stack under direct control. A successful chip production ramp in Austin would help alleviate chip supply constraints for the company.
