Microsoft’s push to recruit people to work on the JEDI project to build cloud infrastructure for the U.S. Department of Defense is in full swing, according to a new report, unhindered by Amazon’s legal challenge of the decision.

CNBC reports that Microsoft has spent the weeks since it was awarded the $10 billion, 10-year contract trying to recruit talent from defense contractors and other companies and get security clearances for its employees working on the project. One source told CNBC that Microsoft has already cleared hundreds of engineers. But another source said the tech giant is facing an 18-month bottleneck getting its employees through the security process.

Microsoft doesn’t have any jobs posted online that mention JEDI by name, however it does have more than 100 open positions for people with security clearances. One job posting spotted by CNBC notes an interview day at the company’s Reston, Va. campus in January for security-oriented positions.

Earlier this week, the U.S. Court of Federal Claims released a redacted version of Amazon’s previously sealed appeal of the award, in which the tech giant accuses President Donald Trump of influencing the Department of Defense as it made its decision. Amazon claims in the complaint that the award of the JEDI project is “impossible to assess separate and apart from the President’s repeatedly expressed determination to, in the words of the President himself, ‘screw Amazon.’ Amazon is asking the court to order the Pentagon to re-open the bidding process.
