Miller, 43, also helped with England’s World Cup preparations in 2019 and worked closely with the Ashes squad. He has also previously worked with a number of current Essex first-team bowlers, including Jamaal Richards, Sam Cooke, Jamie Porter and Aaron Beard, who graduated through the club’s academy system.
“I would like to thank Essex Cricket for giving me this opportunity,” Miller said. “I’ve been involved with the county for a number of years in various roles and it’s an environment I know very well with some exciting talent across the way.
“The opportunity to help develop the next generation of bowlers excites me. Additionally, the county has been very flexible with the franchise work I have been involved in and continues to encourage me to gain more experience overseas.
“I was in the final interview for the head coach role with another first-class county, but when this opportunity came up in a county I call home, I decided to take the role.”
In 2021, Miller was assistant coach of the St Kitts and Nevis Patriots when they won the CPL, after which he spoke about the lack of opportunities to prove his coaching credentials in English cricket.
