After the youth team was closed down in 2011, he joined ENPPI and made his professional debut in the Egyptian Premier League on 18 December 2011 in a match against Wadi Degla. He scored his first senior goal the following season during a match against Telephonat Beni Suef after coming on as a substitute. He was offered a trial with English club Hull City but was unable to go after struggling to obtain a work permit with Hull manager Steve Bruce commenting “he’s a very good player, but getting him into the country long-term will be a problem.”

He instead moved to FC Luzern in the Swiss Super League on loan, with the club having an option to make the deal permanent, in August 2013. He made his debut for the club a week later, coming on as a substitute during a 1–1 draw with FC Basel. On 5 October 2013, he made his first start for Luzern and opened the scoring after 39 minutes during a 2–0 win over FC Zürich, being named man of the match. After establishing himself in the first team, Kahraba scored six further goals for Luzern to become their second highest goalscorer for the season and the club had opened discussions with ENPPI to extend his loan deal for a further season.

Kahraba was part of the Egypt under-20 that won the Africa U-20 Cup of Nations in March 2013 for the first time in ten years, winning the penalty for Egypt’s goal and scoring in the penalty shoot-out after the match against Ghana ended in a 1–1 draw after extra time. He was also named in the team of the tournament and finished the tournament as a joint second-highest scorer with three goals.

Kahraba made his debut for the Egypt senior side on 10 September 2013 in a 4–2 victory over Guinea. He scored his first senior international on 6 September 2015 during a 5–1 victory over Chad. He was named in the squad for the 2017 Africa Cup of Nations and, on 27 January 2017, he scored the winning goal in the quarterfinal of the tournament against Morocco. Egypt went on to reach the final before losing to Cameroon with Kahraba an unused substitute during the final. In May 2018 he was named in Egypt’s preliminary squad for the 2018 FIFA World Cup in Russia. After being selected in the final 23-man squad, he came on as a substitute in all three of Egypt’s group matches during defeats to Uruguay, Russia and Saudi Arabia as they were eliminated in the group stage.

After receiving offers from sides in Spain and Germany, Kahraba eventually signed a loan deal with fellow Swiss side Grasshopper Club Zürich in May 2014. The club paid a fee of €100,000 for a six-month loan deal with an option to sign Kahraba on a permanent deal for €1 million. He began pre-season training nearly a week before the rest of the squad, and made his debut for the club as a late substitute in place of Michael Lang during a 1–0 defeat to local rivals FC Zürich. The following week, Kahraba was sent off after receiving a second yellow card during a 2–2 draw with FC Thun, leaving the pitch in tears.

During his first six months with Zamalek, Kahraba helped the side win the Egyptian Premier League and the Egypt Cup, scoring eight goals in fourteen appearances. His performances led to him being nominated for the 2015 African Most Promising Talent Award. In July 2016, he was suspended by the club after clashing with his coaching staff after he was substituted during a match against rivals Al Ahly.

In July 2016, Kahraba joined Saudi Arabian side Al-Ittihad on loan for the 2016–17 season for a fee of $2 million. He made his debut for the club on the opening day of the season, scoring in a 3–2 victory over Al-Raed on 11 August 2016. In his third game for Al-Ittihad, Kahraba became the first Egyptian player to score a hat-trick in the Saudi Professional League after helping his side to a 5–3 victory over Al-Wehda, scoring four of his side’s goals and assisting the other. He also scored the fastest goal of the season after netting after just 64 seconds of a 4–1 victory over Al-Ettifaq.

His performances led Al-Ittihad to open talks about extending his stay with the club, having scored fifteen goals in twenty appearances including the winning goal in the final of the 2016–17 Saudi Crown Prince Cup during a 1–0 victory over Al-Nassr. Zamalek chairman Mortada Mansour publicly declared that the club would only look to sell Kahraba for offers of €40 million or more. Al-Ittihad later extended his loan spell for a further season, submitting an offer in excess of the $2 million they paid for the first year. In April 2017, he was handed the captaincy for a match against Al-Qadsiah, scoring once as he helped the side to a 4–2 victory. He was fined 500,000 Egyptian pounds by Zamalek in May 2017 after he appeared on an Egyptian TV show without the club’s permission alongside Al Ahly player Moamen Zakaria.

On 25 July 2019, Kahraba signed a two-year deal with Primeira Liga side Aves.

On 13 December 2019, Kahraba signed a four year and half deal with the Egyptian league champion Al Ahly.
