Graeme Welch will work alongside new Leicestershire head coach Pierre de Bruyn after the former Derbyshire elite performance director was named assistant coach at Grace Road.
Welch, 44, resigned from his role at Derbyshire in June having held the position for two year. He was previously the bowling coach for Essex.
Leicestershire named De Bruyn as head coach last month with Andrew McDonald returning to Australia.
Leicestershire chief executive Wasim Khan said: “Graeme will be a fantastic assistant for Pierre with his tremendous experience of county cricket as both a player and coach.
“I’ve known ‘Pop’ for many years and I’m looking forward to him working alongside Pierre as we continue to move the club forward following the excellent work of Andrew McDonald.”
