Twitter has a new product manager in the wake of a large re-org of the company announced this week. The changes will see Twitter dividing its business into groups including engineering, product, revenue product, design and research, and more, while also bringing on Kayvon Beykpour, the GM of video and former Periscope CEO, as product head.

Beykpour will replace Ed Ho, vice president of product and engineering, as Ho steps down into a part-time role. In a series of tweets, Ho explains his decision was based on a family loss, and says he hopes to return full-time in the future. He had been on leave from Twitter since May.

As Recode noted, these change will make Beykpour the sixth exec to head up product since early 2014.

Meanwhile, Ho’s other role — head of engineering — will now be overseen by Mike Montano, who is stepping up from product engineering.

Twitter CEO’s announcement of the changes, below, was tweeted out on Thursday:
