Wanjiru made her international debut at the 2015 African Games and won a silver medal in the 5000 m, forming a Kenyan sweep of the medals alongside Margaret Chelimo and Alice Aprot. The year after she was beaten into second place at the Japan Corporate Championships by another Kenyan, Ann Karindi Mwangi. She repeated as champion at the Oda Memorial and Sanyo Women's 10K.

In 2019, Wanjiru began to compete more frequently outside of Japan. She won the Lilac Bloomsday Run and Cherry Blossom Ten Mile Run in the United States before going on to place third in the 10,000 m at the Kenyan Athletics Championships. This earned her her second international selection for Kenya, this time at the 2019 World Athletics Championships. At the World Championships she teamed up with compatriots Agnes Jebet Tirop and Hellen Obiri to lead the pace. She fell away from the leaders in the final stage of the race and ended the race in fourth place, behind Sifan Hassan, Letesenbet Gidey and Tirop.
