Guha started his career as a journalist in 2007 at the newspaper, DNA (Daily News & Analysis), where he reviewed films. Later, he joined Time Out (Mumbai) magazine as Editor, Film. In addition, Guha has written columns for publications like Mumbai Mirror, The Hindu, Firstpost, and MensXP.
His next as screenwriter, the action thriller film Malang, released in 2020 and was a box office hit.[citation needed]Bollywood Hungama, in its 3.5 star review of Malang, said: “Aniruddha Guha's screenplay ensures most scenes don’t give a strong déjà vu of any film. There’s a lot happening in the film and the script is written in such a way that it does not bore the audience”.[16] For IANS, critic Vinayak Chakravorty wrote that while the core idea may sound cliched, "Aniruddha Guha’s screenplay maintains suspense by opting for a parallel narrative structure".[17] The same year, Guha worked as a story consultant on the show, Code M, a military procedural.[18][19]
In 2021, he wrote the screenplay and additional dialogues of the sports drama film Rashmi Rocket, directed by Akarsh Khurana, released on the streaming platform, ZEE 5, on October 15.[20][21] Ronak Kotecha of The Times of India gave Rashmi Rocket four stars and said, "Nanda Periyasamy’s riveting story, Aniruddha Guha’s sharp screenplay and Akarsh Khurana’s able direction, holds your attention right from the beginning until the end, where the race for justice is played out in a court."[22] In her review for The Quint, film critic Stutee Ghosh gave the film 3.5 stars, and said, "Director Akarsh Khurana and screenplay writer Aniruddha Guha seem to have made a conscious choice to keep the tone upbeat and that works in favour of the film."[23] In her review for Mashable, Sushri Saha wrote, "With strong performances led by Pannu and a well-written screenplay, the film does justice to the issues it raises and challenges."[24]
In April 2024, Guha wrote the screenplay of the series, Ranneeti: Balakot & Beyond, which streams on Jio Cinema.[25] In an interview with First Post, Guha said, “(Ranneeti) is more about what goes on behind-the-scenes during war time. The split-second decision-making, the diplomatic hustle, the collateral to be considered each time, the potential backlash from the international community - these made for very interesting plot points in the long-format space. And we explored these themes from both sides of the border.”[26]
