Mundruczó earned a diploma from Hungary's Academy of Film and Drama in 1998 as an actor, then in 2003 as a film and television director. In that same year, he founded Proton Cinema Ltd., dedicated to film production, along with Viktória Petrányi, a constant co-creator and collaborator in his work and writing since the academy.

Mundruczó's first full-length feature This I wish and nothing more won, among other prizes, the award for best first film at the 31st Hungarian Film Week, as well as its Students’ Jury and Directors’ Guild Awards. He directed his short film Afta shortly after leaving school. It went on to win numerous international awards. Pleasant Days, his second feature film, was awarded the Silver Leopard in Locarno in 2002. In 2003, he won the Cinéfondation Program's artistic grant, within the framework of the Cannes International Film Festival, where he developed the screenplay of the film Delta, together with Yvette Bíró in Paris.

He has been a member of the European Film Academy since 2004.

The first won the FIPRESCI Award.

In 2014, his film, White God – which was invited to Cannes Film Festival and made with the support of Eurimages, the European Council’s film foundation and the Hungarian National Film Foundation[ – won the main prize of the Un Certain Regard program at the 67th Cannes Film Festival.

Mundruczó has worked in theatre and opera since 2003, first in Hungary and then in theatres abroad such as the Thalia Theater in Hamburg, the TR Warszawa, the Schauspielhaus Zürich and the Vlaamse Opera. At the Vlaamse Opera he staged Duke Bluebeard's Castle/Winter Journey in 2014 and The Makropulos Affair in 2016. The latter was nominated in the new production category for the International Opera Awards 2017. His most recent works include Lohengrin at the Bavarian State Opera and Tannhäuser at the Hamburg State Opera. The opera Sleepless by Peter Eötvos, which he directed, was named the premiere of 2022 in the critics’ survey by the specialist magazine Opernwelt. He is most keen to begin new projects where he finds the subject, collaborators and venue inspiring. During the creative process, he strives to create a team. For new projects, he very often casts the same actors, who work with him as creative partners. After freelancing with more or less the same group of people for several years, in 2009, he founded Proton Theatre, his independent theatre company, with producer Dóra Büki.

Proton Theatre is a virtual artistic company organised around the director’s independent productions. Besides preserving maximum artistic freedom, their goal is to ensure a professional structure for their independently produced theatre plays and projects. Chiefly, their performances are realized as international co-productions, and their frequent collaborators include the Wiener Festwochen, HAU Hebbel am Ufer in Berlin,Kunstenfestivaldesarts in Brussels, Trafó House of Contemporary Arts in Budapest and Hellerau in Dresden. Productions directed by the artistic leader include The Ice (2006); Frankenstein-project (2007), which inspired his later film Tender Son,Hard to be a God (2010); Disgrace (2012), based on the post-apartheid novel by Nobel Prize-winner J. M. Coetzee and, in turn, inspiring his film White God; Dementia (2014), Winterreise (2015), Imitation of Life (2016), The Raft of the Medusa (2018), Evolution (2019) inspiring his film with the same title, and The Seven Deadly Sins/Motherland (2020).
