A rising all-rounder in the South African circuit, Mulder started playing cricket in college and was scouted into youth cricket in his teens. A well-built man with broad shoulders, Mulder has shown signs of extravagant strokeplay with an orthodox technique along with some medium-pace and the much sought-after variations in modern cricket. He rose quickly through the ranks and immediately impressed selectors to be selected for the 2016 U-19 World Cup.
He quickly went on to make his debut for the Stellenbosch Monarchs, but the Global T20 league was postponed by Cricket South Africa. He continued to notch up some stellar performances in the domestic circuit and was consequently rewarded with an ODI debut against Bangladesh in late 2017 as a replacement for the injured Wayne Parnell. After failing to impress in his only outing with a single-digit score and one wicket, he was quickly forgotten.
