X has appointed a new chief safety officer almost a year after the last executive in the position resigned. The company said Tuesday that it has Kylie McRoberts as head of safety and hired Yale Cohen as head of brand safety and advertiser solutions.

The two will have the unenviable task of leading X’s safety efforts, including its attempts to reassure advertisers that the platform does not monetize or . The company said earlier this year that it plans to hire 100 new safety officers after that much of the safety staff.

Head of security has been a particularly tough position since Elon Musk took over the company formerly known as Twitter. Musk has previously clashed with his safety leaders and McRoberts is the third person to hold the title in less than two years. Previously, Yoel Roth shortly after Twitter Blue’s disastrous rollout in 2022, Roth was replaced by Ella Irwin, who last year after Musk publicly criticized employees for enforcing gender-incorrect policies.

Not much is known about McRoberts, but she is apparently an existing member of X’s safety team (her X account is currently private and appears recently deleted). “During her time at X, she led initiatives to increase transparency in our moderation practices through tags, improve password security, and build our new Center of Safety Excellence in Austin,” X said in a statement.
