The top lawyer at online real estate company Zillow Group Inc. is packing up and moving into retirement.

Kathleen Philips, who serves as the Seattle-based company's chief financial officer as well as its chief legal officer, will retire from her CFO role at the end of the month, the company announced Monday. She will continue her CLO duties through the end of the year but, after 2018, will still advise Zillow on legal, corporate development and finance matters until her eventual retirement in 2020.

Jennifer Rock, Zillow's vice president of financial reporting, technical accounting and financial planning and analysis, will serve as interim CFO until the company finds a new top financial officer via an executive recruiting firm, according to the news release. Rock also has been running the company's compliance department for seven years. Zillow General Counsel Brad Owens will remain in his current role, according to the company.
