He received his secondary education at Sekolah Menengah Kebangsaan Tanah Merah, Port Dickson before furthering his studies at the MARA Institute of Technology (now UiTM) in the field of business.

Early career From 1991, Aminuddin served a five-year tenure as an investigative officer in the Anti-Corruption Agency (ACA, now MACC). In 1995, he joined Golden Hope Furniture Sdn. Bhd. as head of production management and later MCIS Safety Glass (M) Sdn Bhd as Senior Executive from 1996 to 2008 as head of the sales department, management committee, internal investigation panel and ISO/TS 16949:2002 auditor.

After the 2018 Negeri Sembilan state election, Aminuddin submitted a letter by PKR President Wan Azizah Wan Ismail to Yang di-Pertuan Besar of Negeri Sembilan Tuanku Muhriz, endorsing him as the next Menteri Besar of Negeri Sembilan for the first term and to form a new Negeri Sembilan state government after Pakatan Harapan won the election by gaining the simple majority in the Negeri Sembilan State Legislative Assembly. Three days after the election, Aminuddin was appointed and sworn in as the Menteri Besar of Negeri Sembilan at Istana Besar in Seri Menanti, Kuala Pilah.

In the 2022 general election, Aminuddin was elected for the MP for Port Dickson. In the 2022 PKR party election, he was elected as Vice President with 33,230 votes, the fourth-highest number of votes among the vice presidential candidates.

In the 2023 Negeri Sembilan state election, Aminuddin was reappointed and sworn in again as the Menteri Besar for the second term by winning the election again by securing the supermajority in the State Legislative Assembly with Barisan Nasional (BN). He formed a coalition state government with BN by appointing State Chairman of BN of Negeri Sembilan Jalaluddin Alias as the Senior Exco Member, a position equal to a Deputy Menteri Besar, effectively making him the second most powerful person in the state government as well as three other BN MLAs as Exco Members.

2026 Negeri Sembilan constitutional and political crisis

On 17 April 2026, Aminuddin announced that Dato' Haji Mubarak bin Dohak was removed from his office as Undang of Sungei Ujong, with effect from 13 May 2025, for 33 alleged offences relating to traditional and customary laws. This announcement came after a special session of the Hall of Justices and Undangs (, DKU) chaired by Yang di-Pertuan Besar of Negeri Sembilan, Tuanku Muhriz advised the Luak of Sungei Ujong to accept Mubarak's removal, in which the Klana Hulu of Sungei Ujong's Clan Matriarch and her immediate family were also in attendance.

On 20 April at the Balai Undang Luak Sungei Ujong, Dato' Mubarak and the other three Undangs, namely Dato' Hj. Maarof bin Mat Rashad of Jelebu; Dato' Hj. Muhammed bin Abdullah of Johol; and Dato' Hj. Abdul Rahim bin Yasin of Rembau declared the removal of Tuanku Muhriz on claims of alleged misconduct and named Tunku Nadzaruddin, the Tunku Panglima of Negeri Sembilan and third son of Muhriz's predecessor Tuanku Ja'afar, as the 12th Yang di-Pertuan Besar. Aminuddin rejected the declaration on the grounds that Dato’ Haji Mubarak, who signed and read the declaration, no longer held any authority as Undang having not received the mandate from the Klana Hulu's Clan Matriarch and her family. On the following day, the four Undangs claimed that Mubarak's removal was not valid as the DKU members who were present during the special session did not make a decision on the matter and that the other three Undangs did not agree with Mubarak's removal. On the following month, two individuals, 29-year-old accountant Muhammad Faris Johari and 70-year-old former clerk Abd Rahman, were appointed as the 11th Undang of Sungei Ujong. Muhammad Faris' appointment was officially announced whereas Abd Rahman's was not. Both appointments were respectively disputed.

On 27 April, UMNO withdrew their support to Aminuddin, citing that he did not consult UMNO over the dispute between the Undangs and Muhriz. Negeri Sembilan UMNO later announced that they have accepted Perikatan Nasional's collaboration and have a simple majority to form a new state government. Aminuddin said that he was informed by Tuanku Muhriz to continue his duty as Menteri Besar until there is resolution over the matter. Prime Minister Anwar Ibrahim reaffirmed Tuanku Muhriz's stance after being granted an audience and also said that a state snap election is unlikely to happen. On 30 April, the 14 UMNO assemblymen reaffirmed their support to Aminuddin to ensure political stability. However, the state assembly was dissolved on 5 June with the consent of Tuanku Muhriz.

On the same day, Tunku Nadzaruddin was proclaimed as the 12th Yang di-Pertuan Besar by Undang Luak Jelebu Maarof Mat Rashad, who represented the other three Undangs, at Park Royal A'Famosa Resort, Melaka. The ceremony took place after police obstructed Tunku Nadzaruddin from leaving the resort to head to the Tuanku Besar Tampin official residence for the ceremony. Immediately after, Anwar announced that the federal government still recognises Tuanku Muhriz as the rightful Yang di-Pertuan Besar and that constitutional disputes must be resolved through lawful and established channels.
