Olsson began his career in BKV Norrtälje and joined the youth system of AIK. He was not given a chance in their senior ranks, and made his way up through smaller clubs from the Stockholm area; Sollentuna FK, IK Frej and IF Brommapojkarna.[3]
Olsson was the backup goalkeeper at Brommapojkarna in 2020, but felt the situation "strengthened him mentally". In 2021 he became first choice under a new manager, and kept several clean sheets.[4] Brommapojkarna won promotion from the 2021 Ettan, with Olsson condecing only 18 goals and keeping 17 clean sheets. He was awarded the Ettan Goalkeeper of the Year title.[5]
Brommapojkarna won another promotion from the 2022 Superettan, but Olsson's contract expired. He instead signed with BP's Allsvenskan competitor Degerfors IF.[6] His ascent to the highest league in Sweden was described as "winding".[7]
Starting the 2023 season as backup for Sondre Rossbach, the latter was criticized after a string of heavy losses.[8] Olsson subsequently made his Allsvenskan debut in May 2023 against AIK.[3] Following Degerfors' relegation, he signed a three-year contract with another Superettan team GIF Sundsvall.[9]
