Eric Young, a former vice president of engineering at Alphabet Inc’s Google Cloud, will supervise Snap’s core infrastructure, which includes the popular photo messaging service Snapchat.

Snap Inc announced the hiring of a new senior vice president of engineering from Google on Monday, the latest in a spate of new hires to develop its advertising business.

Eric Young, a former vice president of engineering at Alphabet Inc’s Google Cloud, will supervise Snap’s core infrastructure, which includes the popular photo messaging service Snapchat.

He will also head efforts to improve Snapchat’s capacity to target and measure adverts, which has been hampered by privacy upgrades on Apple’s iOS devices.

While Snapchat‘s audience has grown steadily to 750 million monthly users, the firm has failed to generate income at the same rate.

Snap announced in April that it was simplifying how users engage with ads and improving the relevance of ads presented to users, which it claimed might impact results for some advertisers in the short run.

Eric Young worked at Google on the technical foundation for products such as search, advertisements, and YouTube.

His hiring at Snap follows the hiring of Rob Wilk, former head of advertising at Microsoft Corp, as president of the Americas area, and another Google employee to drive revenue product.
