Almstadt joins from Arsenal, where he has worked as part of the football department for the past four years, including a spell alongside Villa’s chief executive Tom Fox.
Fox told the club website: “I’m really pleased to welcome Hendrik to Aston Villa. I was able to see first hand the excellent work he did at Arsenal and he will add tremendous value across our entire football set-up.”
Almstadt said: “I can’t wait to start my new role at Aston Villa. It is a club with huge potential, a rich history and deep roots in Birmingham, the Midlands, and within English and European football.
“I look forward to working again with Tom Fox and to establish a close relationship with the manager, Tim Sherwood.”
Sherwood said: “I’m really excited Hendrik is joining. We have a lot of work to do at the football club and Hendrik will make the job I have here easier.”
