Domènech made his official – and La Liga – debut with Mallorca on 27 August 2024, coming on as a late substitute for Sergi Darder in a 0–0 home draw against Sevilla FC. He scored his first senior goal on 27 October, netting the B's only in a 3–1 Segunda Federación away loss to Lleida CF.
On 2 January 2026, after being a permanent member of the first team during the first half of the season, Domènech was loaned to Segunda División side AD Ceuta FC until June. He scored his first professional goal on 20 February, netting the opener in a 2–1 home win over Granada CF.
On 22 August 2026, Domènech moved to Atlético Madrid's reserves in Primera Federación on a one-year loan deal.
