Outgoing White House staff secretary Jessica Hertz will become the Ottawa-based firm’s top lawyer next month, she said in a LinkedIn post. New CTO Allan Leinwand was most recently senior vice-president of engineering at Slack; CEO Tobi Lütke announced his hiring in a tweet. (The Logic)

Talking point: Both posts had been open since June, part of a C-suite shuffle involving five members of the top leadership team in 16 months. Leinwand was also previously CTO at enterprise-software firm ServiceNow; he takes over the head engineering role amid Shopify’s efforts to hire more than 2,000 new tech employees this year. Hertz worked for Biden when she was vice-president before a two-year stint in Facebook’s regulatory-affairs department. The high profile of the new executives—D.C. insider-y Politico Playbook broke the news of Hertz’s hire—points to Shopify’s growing prominence as an almost-tech giant in the U.S. The company reports third-quarter earnings on Thursday.
