Born in Malle, Boeckmans began competing as a professional in the second half of the 2009 season, competing for the Silence–Lotto team as a stagiaire. He joined Topsport Vlaanderen–Mercator for the start of the 2010 season, remaining with the team until the end of 2011, when he joined the Vacansoleil–DCM squad for the 2012 season.[5] Boeckmans made his Grand Tour début at the 2012 Tour de France, where he was earmarked as one of the squad's main sprint contenders, along with Kenny van Hummel; Boeckmans took his first top ten placing on stage 4, when he finished eighth on the stage.[6]
After two years with Vacansoleil–DCM, Boeckemans left the team at the end of the 2013 season,[7] to join Lotto–Belisol.[1] He started the 2015 Vuelta a España.[8] However, on the eighth stage, he was involved in a large crash: he was drinking from a bidon and hit a hole in the road, falling hard to the ground. According to Cyclingnews.com, he suffered "facial trauma and fractures, a concussion, broken ribs and a punctured lung" and was placed into an induced coma.[9][10] He was kept in the coma for over a week and was eventually discharged around four weeks after the crash, following major facial surgery in Belgium.[11]
