From 2019 until 2021, Cingolani was Chief Technology and Innovation Officer at Leonardo; before this, he was scientific director at the IIT in Genoa from 2005 to 2019. In April 2019, he joined the board of directors of
Illycaffè. In April 2020, he was appointed non-executive director on
Ferrari's board of directors. He resigned from the board of directors of Ferrari on 16 February 2021. On 12 April 2023, the
Italian government nominated Cingolani as the next CEO of Leonardo, a partially state-owned Italian multinational company specialising in aerospace, defence, and security. Cingolani initially joined Leonardo in 2019, becoming chief technology and innovation officer and spearheading cyber and AI programs, leaving in 2021. Stefano Pontecorvo was made the new Leonardo chairman. In an interview in May 2025, Cingolani stated that Europe would create large defence companies through
mergers and acquisitions. Cingolani returned to the internal negotiations within the
Meloni government on the appointments of the top management of Leonardo,
Enel,
Eni, and
Poste Italiane. Some observed argued that Law No. 60 of 1953 (Art. 6) would make the position of managing director of a subsidiary incompatible with that of former
member of Parliament for a period of one year after leaving office, as in the case of Cingolani. In 2024, the Ethical Finance Foundation submitted a report on this matter to Leonardo's
audit committee. ==Political career==
