In October 2023, Brusberg officially signed a senior contract with Häcken, lasting until the end of 2026. However, he sat out 2024 due to injury and did not play a single match.

Brusberg's first start came in the 2025 Allsvenskan, as the team struggled with injuries in the squad. Brusberg scored against GAIS in a Gothenburg derby in June 2025, then against Halmstad in July.

During Häcken's 2025 spell in Europe, Brusberg scored with a chip in the first minute against Brann in the Europa League third qualifying round at home - the goal was however disallowed by VAR. With Häcken being relegated to the Conference League play-off round, Brusberg scored in a 7–2 routing of CFR Cluj.

On 21 January 2026, Brusberg joined Polish Ekstraklasa club Raków Częstochowa, signing a contract until the end of 2030.
