Jess Ravich, one of the most senior Wall Street executives to have been publicly accused of sexual harassment, has departed TCW, the giant bond-fund manager where he was one of the top officials, according to a TCW spokesman.

Mr. Ravich, as head of the firm’s alternative-products group, oversaw TCW’s investments in areas like lending to companies and commercial real estate. He also served briefly as a board member at the Los Angeles-based firm, which manages about $200 billion.

TCW and Mr. Ravich declined to comment on the reasons for his departure. A spokeswoman for his accuser, a former TCW employee named Sara Tirschwell, said her lawsuit spoke for itself.

Ms. Tirschwell sued TCW, Mr. Ravich and the firm’s chief executive, David Lippman, in January 2018. A former TCW fund manager, Ms. Tirschwell claimed that Mr. Ravich had pressured her into sex. After she stopped having sex with him, Ms. Tirschwell alleged, Mr. Ravich no longer supported the fund she had been hired to manage, making it impossible for her to succeed.
