SAN FRANCISCO — Three former executives at Amazon have been named to new leadership positions at Imperfect Foods, an online grocer seeking to eliminate food waste and build a better food system.

Corey Farrell has been named chief operating officer. Mr. Farrell joins Imperfect Foods after a 15-year career at Amazon, most recently as head of consumables private brands. During his time at Amazon Mr. Farrell also supported business units as a finance leader.

Hetu Patel has been named chief financial officer, effective April 18. Mr. Patel has been with Amazon for the past 12 years, most recently as director of private brands. He also worked as finance director of Amazon advertising and senior finance manager/finance director for Amazon Prime.

Kelly Nigh has joined Imperfect Foods as chief merchandising officer, where she will focus on partnering with the company’s network of suppliers to build an assortment of products with a focus on reducing food waste, including a private label line. Ms. Nigh was with Amazon for more than 11 years, most recently as global sourcing leader for softlines private brands. Prior to Amazon she was director of sales development for the Seattle Storm.

“Hetu, Corey and Kelly each have exceptional backgrounds in rapidly scaling e-commerce businesses,” said Dan Park, who was named chief executive officer of Imperfect Foods in January. “Combined, that expertise will allow us to grow the business, while simultaneously improving the customer experience and deepening our commitment to reducing food waste. By bringing in new best-in-class talent, we’re able to continue on our mission in a meaningful and reinvigorated way, further optimizing our internal operations and optimizing the customer experience.”
