Marian Aioani

Chindia Târgoviște

Aioani started his senior career with Chindia Târgoviște on 9 March 2016, at age 16, recording his debut in a 7–0 Liga II thrashing of CSM Metalul Reșița. He became an undisputed starter in the 2018–19 campaign, as his side achieved promotion to the Liga I by winning the second division. Aioani's first match in the former competition came on 15 July 2019, playing the full 90 minutes in a 2–2 away draw with Gaz Metan Mediaș.

Farul Constanța

On 22 June 2021, Aioani agreed to a four-year contract with fellow Liga I team Farul Constanța, being part in a swap deal which took several players in the other direction. In the 2022–23 campaign, Aioani made 39 league appearances to help Farul in winning the national title. He had the most clean sheets (13, shared with Mihai Popa) and was named in the Liga I Team of the Season. On 12 July 2023, he made his debut in European competitions by playing in a 1–0 home win over Sheriff Tiraspol in the UEFA Champions League first qualifying round.

Rapid București

On 23 January 2024, it was announced that Aioani joined Rapid București on a three-and-a-half-year deal for a rumoured fee of €400,000 plus 20% interest on a future sale. Four days later, he made his debut in a 2–1 league derby win over Dinamo București.

Aioani was selected by manager Adrian Mutu in the Romania squad for the 2021 UEFA European Under-21 Championship, but did not make any appearance as his nation exited the tournament in the group stage. He was then called up to the postponed 2020 Summer Olympics, this time starting in all three matches of another group-stage exit.
