She had short spells with Division 1 Féminine team ASPTT Albi in 2014 and National Women's Soccer League club Houston Dash in 2015.
A longer stint at FA WSL club Sunderland from 2015 to 2018 was interrupted by injury and illness, before she spent a year in Italy with Florentia in 2018 and 2019.
She was absent for almost two years after breaking her leg in during Ireland's failed 2019 FIFA Women's World Cup qualification campaign, but was recalled in August 2019.
[3] She has worked for RTÉ as a television pundit, covering events including the 2018 and 2022 editions of the FIFA World Cup,[4] and UEFA Euro 2020.
[11] In the inaugural 2011–12 Women's National League season, Zambra won the Golden Boot by scoring 26 goals for champions Peamount United.
[17] Zambra scored an acclaimed goal for Peamount against Wexford Youths in October 2013 which went viral on YouTube and brought her international attention.
[20] Zambra was glad it was captured for posterity: "It's just good for us now to get that on camera, it gives the Women's National League a bit of publicity as well as girls' football in Ireland, and I'm happy to be a part of that as well.
[28] She failed to settle in France, scoring once in ten appearances[2] before quitting the club amidst the FIFA Puskás Award publicity.
He had to release Zambra to free up an international slot and roster space for defensive reinforcements Camila Martins Pereira and Ellie Brush.
[37] She sustained a broken leg while on international duty in September 2017 and was released from her Sunderland contract in Summer 2018, when the club failed to secure a license for the top two tiers of women's football in England.
[38] A consistent run of games at the end of the season saw a return to form for Zambra, who scored twice and was named Player of the Match in Peamount's 6–0 2020 FAI Women's Cup Final win over Cork City.
[46][47] Zambra's appearance on the reality television show Special Forces: Ultimate Hell Week disrupted her preparations for the 2021 Women's National League season.
Although she scored nine goals in 26 appearances, tiredness and minor injuries continued to reduce her effectiveness as Peamount lost their WNL title to Shelbourne on the final day.
[48] Nevertheless, Peamount manager James O'Callaghan was pleased when Zambra agreed to return for the 2022 Women's National League season, rejecting transfer offers from DLR Waves and Bohemians.
[50] On 8 December 2022, it was announced that Zambra would be joining the newly reformed Shamrock Rovers women's team ahead of the 2023 season, following other former Peamount players Áine O'Gorman and Summer Lawless to the Tallaght outfit.
[51] Zambra faced a demanding schedule as she had agreed to participate in the sixth season of Dancing with the Stars alongside training with her new club.
[60] In September 2009, Zambra scored her first senior goal, a late winner in the 2–1 World Cup qualifying win over Kazakhstan at Turners Cross.
[63] National coach Susan Ronan dropped Zambra from the squad for a friendly with Austria in June 2013 and the subsequent 2015 FIFA Women's World Cup qualifiers.
[65] On 5 April 2014 in a 2015 FIFA Women's World Cup qualifier against Germany at Tallaght Stadium, Zambra equalised the game at 2–2 in the 89th minute.
[69] When Ronan decided to step down as national team coach, Zambra scored a "stunning 25-yard free-kick" in her farewell match, a 2–1 win over the Basque Country at Tallaght Stadium on 26 November 2016.
She returned to training in January 2018 but experienced knee pain when kicking the ball, then further scans detected another fracture and meniscus damage.
"[41] Ireland's interim manager Tom O'Connor recalled Zambra after almost two years for the opening UEFA Women's Euro 2022 qualifier against Montenegro at Tallaght Stadium on 3 September 2019.
[78] Following an injury to Kyra Carusa, Pauw recalled Zambra in June 2022 for a friendly against the Philippines in Antalya, Turkey, and a 2023 FIFA Women's World Cup qualification – UEFA Group A fixture against Georgia.
