In January 2011, Ujah was linked with a move to England with Football League One clubs Swindon Town and Southampton reportedly interested.[6] On transfer deadline day, Ujah travelled to La Liga side Mallorca to discuss a move after Lillestrøm accepted a bid for the striker.

Mainz 05
In June 2011, Ujah signed for Mainz 05, after being tracked by several clubs, most notably Danish outfits F.C.

1. FC Köln
On the last day of the summer 2012 transfer window, Ujah signed for 1. FC Köln on a season-long loan.[19] He scored 13 goals in the 2012–13 2. Bundesliga and the transfer was made permanent at the end of the season.[18][20]

Ujah was the club's top scorer in the 2014–15 Bundesliga season, scoring 10 goals.[18][20] In March 2015, Ujah made headlines for his celebration after scoring a goal against Eintracht Frankfurt; the striker ran towards the club's goat mascot, Hennes, and grabbed its horns.[21]
In 2020 Ujah described his spell at Köln as the best time in his career.[22]
Werder Bremen
On 5 May 2015, Werder Bremen announced that they had triggered Ujah's release clause and he would join the club for the 2015–16 season.[23][24] On 24 October, Ujah scored a brace against his former club Mainz as Werder earned a 3–1 away win following five successive defeats.[25] Four days laters, he netted again, helping Werder to a 1–0 victory over his former club 1. FC Köln in the second round of the DFB-Pokal.[26] It was his first goal in a home match at the Weserstadion.[27]
Liaoning Whowin
On 5 July 2016, Werder Bremen announced Ujah would be joining Liaoning Whowin pending a medical for a reported transfer fee of €13 million.

Return to Mainz 05
In December, it was announced that Ujah would return to the Bundesliga having re-signed with former club Mainz 05 on a 3+1⁄2-year contract until 2021.[32] Although he only scored four league goals in his second spell at Mainz, Ujah did help Mainz beat rivals Eintracht Frankfurt 2-0 in May 2019 with a brace.[15][18]
Union Berlin
In June 2019, Ujah's move to Union Berlin, newly promoted to the Bundesliga, for the 2019–20 season was agreed. He signed a three-year deal.[33] Ujah contributed three goals in his first season for Union, but spent a long time out injured and was released in summer 2022.[34]
Eintracht Braunschweig
On 2 August 2022, Ujah signed with Eintracht Braunschweig on a one-year contract, with an optional extra year.[35] His contract was renewed for a second season after Eintracht Braunschweig avoided relegation, with Ujah contributing ten goals and five assists in the 2. Bundesliga.[36]
Botev Plovdiv
On 19 June 2024, Ujah moved to Bulgaria, signing a deal with Botev Plovdiv.[37] In July 2024, he scored in both legs of the UEFA Europa League qualifying matches against Maribor, which saw Botev Plovdiv prevail 4:3 on aggregate.[38] In August 2024, in the return encounter of the next round against Panathinaikos, Ujah suffered a torn ligament, which subsequently necessitated a knee operation and is expected to sideline him for a number of months.[39]
International career
At the end of May 2011, Ujah was called up to the Nigeria national U23 team that faced Tanzania on 5 June 2011.
