Sirtis started her career as a member of the repertory company at the Connaught Theatre, Worthing, West Sussex, in 1976. Directed by Nic Young, she appeared in Joe Orton's What the Butler Saw and as Ophelia in Hamlet.[8]

Before her role in Star Trek, Sirtis was featured in supporting roles in several films. In the 1983, Faye Dunaway film, The Wicked Lady, she engaged in a whip fight with Dunaway. In the Charles Bronson sequel Death Wish 3, Sirtis' character is a rape victim. In the film Blind Date, she appears as a prostitute who is murdered by a madman.

Other early works include numerous guest-starring roles on British television series. Sirtis appeared in Raffles (1977), Who Pays the Ferryman (1977), Hazell (1978), Minder (1979), the Jim Davidson sitcom Up the Elephant and Round the Castle (1985), and The Return of Sherlock Holmes (1986). She also played the flight attendant in a 1979 Cinzano Bianco television commercial starring Leonard Rossiter and Joan Collins, in which Collins was splattered with drink.

In 1986, Sirtis relocated to the United States. When casting Star Trek: The Next Generation, Gene Roddenberry was inspired to ask Sirtis, whose appearance he considered "exotic", to audition for a role after seeing the film Aliens with Bob Justman, which featured the prominent Latina character Vasquez, played by Jenette Goldstein.[9] Sirtis and Denise Crosby initially tried out for each other's eventual roles on The Next Generation. Sirtis' character was going to be named Lt. Macha Hernandez, the Security Chief. Gene Roddenberry decided to switch them, and Macha Hernandez became Tasha Yar. Sirtis recalls that on the day she received the call offering her the role, she was actually packing to return to Britain because her six-month visa had expired.

Deanna Troi is a half-human, half-Betazoid. Her Betazoid abilities allow her to read the emotions of others. Her position on the Enterprise-D is ship's counselor, looking after the crew's well-being and serving as trusted advisor to Captain Picard, with a position next to him on the bridge. Initially, the writers found it difficult to write for Troi and even left her out of four first-season episodes. Sirtis felt her job was in jeopardy after the first season, but was overjoyed when Roddenberry took her aside at Jonathan Frakes' wedding and told her that the season-two premiere episode would centre on Troi.[10]

Sirtis appeared in all seven seasons of Star Trek: The Next Generation, and her character was developed from a more passive therapist to a tougher Starfleet officer. She has stated her favourite episode is season six's "Face of the Enemy", in which she is kidnapped and surgically altered to pose as a Romulan. Troi's switching to a standard Starfleet uniform in the same season in "Chain of Command" elevated the character's dignity in Sirtis' eyes, and her enthusiasm in playing her, with Sirtis commenting, "It covered up my cleavage and, consequently, I got all my brains back, because when you have a cleavage you can't have brains in Hollywood. So I got all my brains back and I was allowed to do things that I hadn't been allowed to do for five or six years. I went on away teams, I was in charge of staff, I had my pips back, I had phasers, I had all the equipment again, and it was fabulous. I was absolutely thrilled."[11]

During her time on the show, she became close friends with her co-stars Jonathan Frakes (who played Commander Riker), Michael Dorn (Lieutenant Worf) and Brent Spiner (who played Lieutenant Commander Data). The latter cast members were groomsmen at her wedding.[12]

She wore black-coloured contact lenses during the seven-year run of Star Trek: The Next Generation and the subsequent films because her character had black eyes.[13] Her own eyes are light brown.

She usually wore hairpieces for her role as Troi. Sirtis' real hair was slightly shorter and, although curly, was not as bouffant as her character's. However, Sirtis' real hair was used in the pilot episode, and also in the first six episodes of season six, in which Troi sported a more natural looking pony-tailed style. She was also asked to create an accent (described as a mixture of Eastern European and Israeli)[14] for her character, although her natural accent is Cockney. Over time, the accent was adjusted and became more Americanized.

Sirtis reprised her character in the feature films Star Trek Generations (1994), Star Trek: First Contact (1996), Star Trek: Insurrection (1998), and Star Trek: Nemesis (2002).

Sirtis was delighted to get the chance to do some comedy in Star Trek: First Contact and said, "I loved it because it opened the door to a different side of Troi we'd never seen before. That door has stayed open and that whole kind of wacky, zany Troi thing has continued into the next movie, which is great for me because I like to do things that are different."[15] Sirtis stated of her role in Star Trek: Nemesis, "I sort of had an inkling that I was going to have a good part in this film because John Logan was such a big fan of the character. So I knew that he would do her some justice."[16]

Sirtis also appeared in Star Trek: Voyager for three episodes toward the end of the series (1999 and 2000), and the series finale of Star Trek: Enterprise (2005). She next returned to her role as Deanna Troi in 2020 in Star Trek: Picard episode "Nepenthe".[17] She also reprised the role in "No Small Parts", the first-season finale of Star Trek: Lower Decks.

While filming Star Trek: The Next Generation, Sirtis returned to the UK during the hiatus between seasons three and four in 1990 to film a drama special entitled One Last Chance for the BBC. In 1992, she appeared in an episode of the short-lived series The Fifth Corner and had a cameo in the horror/fantasy movie Waxwork II: Lost in Time. After the end of Star Trek: The Next Generation in 1994, Sirtis continued to work regularly. Her first role was a departure from previous work, an abused wife in the series Heaven Help Us.

She provided the voice of Demona in the animated Disney television series Gargoyles for two seasons starting in 1994. Her Next Generation co-stars, Frakes (as the voice of David Xanatos), Spiner and Dorn, also lent their voices to the show. She voiced the character again for an episode of the unmade animated series Team Atlantis.
