Instacart announced on Tuesday a series of promotions among top leadership across the company alongside news of an upcoming exit in its c-suite.

After four years with the company, Chief Technology Officer Mark Schaaf is planning to “take a break with family and pursue new opportunities,” Instacart said in the post. Varouj Chitilian, who is currently vice president of engineering, will replace Schaaf. 

Chitilian played a “key” role in scaling the Instacart App and modernizing the technology for it, and has also had a hand in hiring several essential senior engineers and leaders, the post noted.

Schaaf joined Instacart in 2018 as the company’s first CTO. He helped scale the company’s technology throughout the pandemic, the post noted, and recently oversaw the launches of Instacart Platform, a refreshed subscription service and a series of new tools for its gig workers.

Meanwhile, Vice President of Retail Chris Rogers is taking on the expanded role of chief business officer. Rogers is adding the brand partnerships team to his oversight, which includes retail operations. 

Instacart noted that Rogers, who has been with Instacart for three years after more than a decade at Apple, brings “deep expertise in strategic and commercial relationships” to his expanded role and that his work has helped Instacart grow its number of grocery partners from 300 banners when Rogers started with the company to more than 800.

Instacart said Rogers’ expanded role comes as the company looks to more closely align its retail and brand partnerships teams: “By combining these teams, we believe we can create solutions that drive more value for all of our partners.”

Instacart also detailed several other promotions:

• JJ Zhuang is becoming Instacart’s first chief architect. Zhuang, who was most recently head of infrastructure and has been at Instacart for four years, will focus on technology and architecture decisions across product pillars, and how engineering aligns with the company’s long-term business strategy. Zhuang will work closely with Chitilian.
• Daniel Danker has been promoted from head of product to chief product officer.
• Laura Jones has been promoted from head of marking to chief marketing officer. Jones and Danker both started at Instacart in 2021, the blog post noted. 

The promotions follow a string of hires from high-profile companies in 2020 and 2021, which included bringing on former executives from Uber, The New York Times, Facebook, Microsoft, LinkedIn and YouTube. Last summer, Instacart tapped Fidji Simo, a high-ranking Facebook executive, to be its new CEO, and at the end of last year, saw Carolyn Everson, a former Facebook executive who became Instacart’s president in September, leave the top role after a few months.
