Irving has held several roles at BioWare since joining the company in July 2011, including lead development director and lead producer on Star Wars: The Old Republic.
He took on the position of lead producer on Anthem in April 2017, and was responsible for combat, creatures, gameplay, progression systems and UI, according to his LinkedIn profile.
“I have made the decision to move on and have accepted an exciting opportunity at another gaming company,” he said on Twitter.
“Since the first time I played Baldurs Gate many many years ago, BioWare was the dream place I always wanted to work.
“I will forever be grateful to all the people who gave me the chance to work on great products with amazing people.
“I believe Anthem has a bright future – there is a great team working on it and I look forward to following its progress (and playing it!) from the sidelines.”
