Jones' acting career began in 2010, aged 8 years old, when she appeared as Jasmine in the film One Day. She also portrayed Alice in the Channel 4 drama Utopia, and later that year played the young Queen of Years Merry Gejelh in the British television series Doctor Who episode "The Rings of Akhaten" (2013). The Boston Standard lauded Jones for "carr[ying] off her scenes with aplomb" and for "really sell[ing] Merry’s mixture of naivety, knowledge and childlike fear," while the website Zap2It praised Jones' performance for being "spot on." In film, Jones has had small roles in One Day (2011) and Pirates of the Caribbean: On Stranger Tides (2011).

In 2011, Jones made her theatrical debut after playing the Princess Young Fiona in the original cast of Shrek the Musical at the Theatre Royal, Drury Lane. In 2013, Jones appeared in Rebecca Lenkiewicz's stage adaptation of Henry James's The Turn of the Screw. She held the role of nine-year-old Flora with two other girls, alternating between them each night. After her performance on press night, Jones commented, "I don’t find it scary, I just find it so much fun. I love every bit of it."
