Following a guest role on the Israeli television series ‘Ulai Hapa'am’ (‘Maybe This Time’, 2007), Yael Grobglas bagged her first major role in the sci-fi series ‘Ha'Yi’ (‘The Island’, 2007-09), which earned her popularity among young Israeli audiences. In 2010, she gained further recognition for playing one of the main characters in the Israeli film ‘Rabies’ (‘Kalevet’), which was marketed as “the first feature-length Israeli horror film”. The same year, she was part of the main cast of the Israeli sitcom ‘Hashualim’ (‘The Foxes’) and also portrayed the role of Linda Christie in a Beersheba Theater adaptation of ‘Play It Again, Sam’. In 2011, she had recurring roles in the sitcom ‘Ramzor’ (‘Traffic Light’) and the supernatural drama series ‘Split’ (‘Hatsuya’), and also appeared in the sitcom ‘Bnot HaZahav’ and the miniseries ‘Yehefim’ (‘Barefoot’). Moreover, she featured in the music video of the song ‘Say You Like Me’ by the American rock band We The Kings. She next made a couple guest appearances on the Israeli comedy-drama series ‘Tanuchi’ (‘Chill’) in 2012.
In 2013, Yael Grobglas briefly travelled to Los Angeles, California, United States for audition and landed the lead role of America Singer in The CW's pilot for ‘The Selection’, based on a five-book series by Kiera Cass, which unfortunately was never made into a full series. However, the same year, she was cast in the recurring role of Olivia D'Amencourt in The CW's historical romantic drama series ‘Reign’. She also appeared in two episodes of the Israeli television series ‘Sabri Maranan’ in 2013. Her biggest role came in 2014 when she was cast as Petra Solano, one of the main characters of the American romantic comedy-drama series ‘Jane the Virgin’, which she portrayed in 98 episodes of the series throughout its five seasons until 2019. Not only did she enjoy playing the “calculating, resourceful and manipulative” character very unlike her, her ability to mix humor and emotion in portraying the amusingly complex comic villain earned her praise from several leading American publications.
Yael Grobglas returned to her home country to star in the lead in the English-language Israeli supernatural horror film ‘JeruZalem’ in 2015. Also that year, she reprised her role as Amit from ‘Sabri Marnan’ in an episode of the Israeli sitcom ‘HaPijamot’ (‘The Pyjamas’). After acting in the American short film ‘Grace Note’ (2016), she made guest appearances in a couple The CW series like the romantic musical comedy-drama series ‘Crazy Ex-Girlfriend’ (2016) and the superhero series ‘Supergirl’ (2017-18). In 2018, she was one of the main casts in the American drama film ‘An Interview with God’. She subsequently made a cameo appearance as a restaurant patron in a grand finale episode of Gordon Ramsay’s reality cooking competition show ‘Hell's Kitchen’ in 2019. Grobglas, who announced her pregnancy later that year, recently resumed acting after a few years with a couple guest appearances on the Amazon Prime adult animated psychological comedy drama series ‘Undone’ (2022).
