IBM engineer Alex Hines has released a letter to his boss, saying he has become a whistleblower.
The IBM engineer is a senior software engineer at Microsoft.
In the letter, which was published on the company’s website, he says Microsoft’s “systemic failures, including the Windows Vista disaster” have left IBM employees with little confidence in their work and are leading to the resignation of top managers.
“This is a very difficult time for IBM.
In fact, we are in a position where we may be the last company in the world that is not taking responsibility for its mistakes,” Hines writes in the letter.
Hines says he was told to “stand down from my role at Microsoft” after a report surfaced that he had lied about his experience as a Microsoft engineer in a 2009 interview.
Microsoft did not immediately respond to a request for comment on Hines’ accusations.IBM has also faced criticism from lawmakers and business leaders for hiring less than 100 engineers in 2015.
In March, the Senate voted to censure IBM and its top executives over hiring practices, but it is unclear whether the company will face sanctions for the hires.
Microsoft did not respond to requests for comment.
