Bulmer started his career as a youth player at 20-time Premier League Champions Manchester United, before making the move to London with Queens Park Rangers as a 16-year-old.

His first venture into men's football came through a loan at Hayes & Yeading United in the Vanarama National League during the 2010/11 season until he made the switch to Welsh football by signing for Airbus UK Broughton in 2011.

The 32-year-old spent three seasons at The Wingmakers, which were followed by brief spells at Rhyl and Connah's Quay Nomads, before a return to Airbus UK Broughton came for the 2016/17 season and then a move back to England with Mossley.

A transfer to Flint Town United saw Bulmer return to Wales in 2017, which led to a short stint at Bangor City and Cefn Druids. He then signed for Prestatyn Town for the 2021/22 season before signing for Llanidloes Town in 2023.

He now makes the move to Gresford Athletic to provide some valuable competition for Lewis Dutton in the goalkeeping department.

Gresford Athletic First Team Assistant Manager Jonathan Hill-Dunt is happy with the addition of Bulmer:

"Nik is an experienced keeper who is looking to get back involved after some time out.

"He's played at the highest level in Wales and will be a great addition to the squad, working with Lewis."
