Jamie Blamire signed his first senior academy deal with the Falcons in the summer of 2016. The Cumbrian hooker is a graduate of the club's AASE scheme at Gosforth Academy, who has been capped by England at Under-18s and 20s level. The Workington native has played club rugby for Tynedale along with his Falcons commitments, where he comes under the tutelage of Newcastle first-team hooker Scott Lawson. Capped by England Under-18s in 2016 during their tour to South Africa, he helped England Under-20s to a Grand Slam during 2017 and was part of the under-20s squad which reached the final of the Junior World Championship in Georgia that summer. Making his first team debut from the bench during the 2017-18 European Challenge Cup win in Bordeaux, Blamire appeared a further two times from the bench that year before helping the Falcons to the final of the 2018 World Club 10s in Mauritius. He scored the try which sent the Falcons through to the semi-finals of the Premiership Rugby Cup at Sale Sharks in February 2019, also scoring on his Premiership debut at Gloucester in May 2019 after coming on as a back-row replacement. Part of the squad which helped the Falcons to the 2019 A-League final, Blamire was named Academy Player of the Season for 2018-19. Helping the Falcons to promotion in 2019-20 and playing 18 games during the 2020-21 season, he scored on his full England debut against the USA in July 2021 just three minutes after coming on as a replacement, following up with a hat-trick in his second cap against Canada the week after.
