The 24-year-old is also comfortable playing as a forward, and will be a familiar face to Bromley supporters.
As a youth player, Coulson spent ten years at Manchester City, before enrolling as a student at the University of Michigan, playing for the Michigan Wolverines.
After just a month, however, Coulson made the move back to the UK after interest from Championship and Premier League clubs.
Following this, he signed for Cardiff City, making his debut against Macclesfield Town in January 2013.
After being offered a new deal at the end of the season, Coulson opted to move on in search of regular first-team football.
After trials with Football League clubs, he joined Oxford City.
Following some eye-catching performances, with goals to his name, National League side Eastleigh came calling, making him their record signing.
Coulsonís form continued with the Spitfires, and he was snapped up by then-League Two side Barnet. Soon after, however, Ebbsfleet paid an undisclosed fee for Coulsonís services, bringing him on board in July 2017.
After signing for the Ravens, Coulson told http://www.bromleyfc.tv: ďIím delighted itís all happened so quickly. Everyone has been really friendly, and I very much enjoyed my first training session. Iíve been told all about where the club wants to be in the next few years, and thatís a huge reason why Iíve bought into itĒ.
