Caldirola started his career at Internazionale, where he was the team captain at under-20 level (Primavera) and was occasionally called up to join the first team during the 2009–10 season, without making any appearances, however, on the pitch. Caldirola also played for various youth teams in Lombardy as goalkeeper and midfielder before joined Internazionale at the age of eight. He played in a friendly match for the Inter first team in 2009.
On 29 June 2010, Internazionale loaned out Caldirola to Dutch club Vitesse Arnhem of the Eredivisie for the entire 2010–11 season; he is the second Italian player to be part of the Arnhem club, after Marco De Marchi. Inter also reduced the age limit of its Primavera team to under-19 in 2010, keeping only three players born in 1991 in the 2010–11 season as back-ups for the first team.
Half of the registration rights of Caldirola — and Luca Garritano — were sold to Cesena as part of the deal that brought defender Yuto Nagatomo to the San Siro in June 2011, after a successful loan. Half of the registration rights of Caldirola was valued €2.5 million; Caldirola signed a four-year contract. Both Caldirola and Garritano returned to Internazionale in a temporary deal for the 2011–12 season.
In June 2012, the co-ownership deal was renewed and Caldirola reported to Cesena in pre-season on 10 July 2012, where he played the first half of the season for the Romagna club before again being loaned to Brescia in January 2013, where he finished the campaign with 15 league appearances.
In June 2013 Inter bought back Caldirola for €2.5 million, with Riccardo Melgrati and Thomas Pedrabissi moved to Cesena outright for €750,000 and €1 million respectively; Cesena also signed Yago Del Piero in co-ownership deal for €250,000, thus the deals only involves €500,000 cash to Cesena.
On 26 June 2013, SV Werder Bremen confirmed the signing of Luca Caldirola from Internazionale on a four-year contract, for a €2.5 million transfer fee. Upon signing for the Bundesliga club, Caldirola stated: "Werder is a great opportunity for me, I immediately said that I would like to switch to Werder. The club has a great tradition."
