Twitter’s chief information security officer Lea Kissner is leaving the company, Kissner said in a tweet today.
Kissner joined Twitter last year as head of privacy engineering and was named chief information security officer in January.
The move comes amid a large-scale layoff and product changes at the social media company under new chief Elon Musk.
Musk bought Twitter for $44 billion and took control on October 27. He then moved quickly to remove several top executives, including Chief Executive Officer Parag Agrawal, and announced layoffs affecting about half of Twitter’s workforce.
Chief privacy officer Damien Kieran and chief compliance officer Marianne Fogarty have also released their documents, the Verge reported earlier Thursday, citing sources and messages on Twitter’s internal channels.
Twitter did not immediately respond to a request for comment on the departures.
