Speers began his major junior career playing with the
Sault Ste. Marie Greyhounds in the
Ontario Hockey League before he was drafted in the 3rd round, 67th overall, by the
New Jersey Devils in the
2015 NHL entry draft. On September 21, 2016, Speers signed a three-year entry-level contract with the Devils. On October 11, 2016, it was announced that Speers had made the Devils opening night roster for the
2016–17 season. He made his NHL debut on October 13, 2016 in a 2–1 overtime defeat against the
Florida Panthers. After three scoreless games with the Devils, Speers was returned for his final junior eligible season with the Greyhounds on October 24, 2016. On December 16, 2019, Speers was traded to the
