Twitter's chief technology officer Adam Messinger said he would resign from the company in a Tweet.
After 5 years I’ve decided to leave Twitter and take some time off. Grateful to @jack for the opportunity and to my team for shipping.— Adam Messinger (@adam_messinger) December 20, 2016
Messinger joined Twitter in 2011 and previously worked as the social media company's vice president of application development.
Cheif executive Jack Dorsey thanked Messinger in a Tweet.
Thank you for everything you've done for Twitter Adam! I have learned so much from you, and appreciate everything you stand for. 🙏🏼 https://t.co/xdnZ9gdnnO— jack (@jack) December 20, 2016
Vice president of product Josh McFarland also announced he would leave Twitter to join Silicon Valley venture firm Greylock Partners, Reuters has reported.
McFarland will leave Twitter early next year, almost two years after he joined.
Four senior executives left the struggling San Francisco-based company in January, and another two executives left in May.
