Musk applies his three-bullet hiring filter to electricians and cooling specialists as SpaceX expands the Colossus AI campus and eyes orbital data centers.
Elon Musk is extending his trademark hiring filter beyond white-collar roles. SpaceX posted on X last week that it needs “exceptional engineering & skilled trades talent” to build and operate AI supercomputer clusters on Earth and in space. Interested candidates must email three bullet points “demonstrating evidence of exceptional ability” along with a resume to datacenters@spacex.com.
The three-bullet requirement has long been a fixture of Musk’s recruiting playbook. He has used it for engineers, executives, and now for the electricians, pipefitters, and cooling specialists who construct and run hyperscale data centers. The posting explicitly calls for skilled trades workers, a population that typically applies through union halls or contractor portals, not self-promotional bullet points.
The hiring push reflects SpaceX’s expanding role in Musk’s AI ambitions. Earlier this year, SpaceX acquired Musk’s AI startup xAI and rebranded it as SpaceXAI. The unit operates Colossus, a massive AI supercomputer campus in Memphis, Tennessee, that trains the Grok language models. A second Colossus expansion is reportedly underway, and the “off Earth” line in the job post hints at Musk’s long-standing idea of putting data centers in orbit to bypass terrestrial energy constraints.
Skilled trades workers who can handle the electrical loads, liquid cooling loops, and high-voltage gear inside AI clusters are in short supply. Hyperscalers – Amazon, Microsoft, Google – are competing for the same labor pool. SpaceX is offering a different pitch: spaceflight heritage and the possibility of working on orbital infrastructure. Whether that lure is enough to attract union electricians remains an open question.
No headcount or budget figures accompanied the posting. The Colossus campus already draws 150 megawatts of power, and plan documents filed in Memphis suggest the site could grow to more than 1,000 megawatts over several phases. Each megawatt of AI compute requires roughly 5-10 skilled trades workers during the build phase, plus 1-2 operators once live, according to industry estimates cited by data center developers. If Colossus scales as projected, the hiring need is in the hundreds or thousands.
SpaceX did not say whether candidates who submit three bullets will get priority attention. The company’s track record with the format suggests the filter is genuine: Musk has said he personally reviews qualified candidates’ bullet points for white-collar roles. Whether he does the same for trades applicants was not specified in the post.
The “off Earth” piece of the call-out is the most speculative element. Placing data centers in space would solve the energy problem – orbital solar provides round-the-clock power with no land-use constraints – but it introduces enormous cost and latency challenges. SpaceX’s Starlink constellation demonstrates the company can mass-produce orbital hardware. That capability is one reason Musk can even float the idea.
For the rest of the industry, the message is concrete: AI infrastructure buildout is shifting from software design to physical construction. Companies that supply electrical gear, cooling kits, and modular data center components are likely to see demand accelerate. SpaceX’s explicit recruitment of trades workers underscores the scope of the build, both terrestrial and orbital.
