Rosberg won the 2005 GP2 Series for the ART team, having raced in Formula 3 Euro Series previously for his father Keke Rosbergs racing organisation Team Rosberg.

For the 2010 Formula One season, Rosberg joined the re-branded Mercedes team, formed by Mercedess takeover of 2009 constructors champions Brawn GP. Since then, Rosberg has enjoyed his most successful period, winning 6 Grands Prix and earning 7 pole positions.

In late 2005, Rosberg was officially confirmed as a Williams driver for the 2006 season. In the Engineering Aptitude Test, administered to all new Williams drivers, Rosberg achieved the highest score in the teams history. In the first Formula One race of his young career in Bahrain, Rosberg was driving a car which was not considered competitive enough to get to the podium. and also had to fight his way through the field after losing his nose cone on the first lap. Nonetheless, he finished in the points, seventh behind teammate Mark Webber, and recorded the fastest lap, becoming the youngest driver to do so in F1 history. Following this he was linked with a move to teams such as McLaren.

He qualified third at the next round Malaysia, but his Cosworth engine, on its second mandatory race, blew up after only seven laps. Rosberg did get into the points for the second time in the 2006 season at the European Grand Prix, benefiting from the hydraulic failure of his teammate.

The rest of the 2006 season went less well for Rosberg; he retired in four of the next seven Grands Prix, and in the ones he did finish he was outside the points. His closest attempt to get into the points was in Britain, where he was just one second behind eighth placed Jacques Villeneuve. Rosberg scored a total of four points, three fewer than teammate Webber, over the course of what was a disappointing season for both himself and for the Williams team.

In 2007, Rosberg finished in the points seven times, including a career best fourth at the season-ending Brazilian Grand Prix. He was also placed seventh in the Australian, Hungarian and Turkish Grands Prix and came home sixth at the Italian and Belgian Grands Prix. At the Canadian Grand Prix, Rosberg qualified seventh and moved up two places from the start:

"Early in the race I thought I was set for a good result because I was running fifth and the car felt really good, but then the Safety Car came out on lap 21... I had to stop for fuel on lap 23, which meant I missed the re-fuelling window by 13 seconds and that effectively ended my race. New rules punish people who pit immediately after the Safety Car comes out, so I was given a 10s stop-go penalty and all I could manage after that was 10th place."

He suffered only three retirements during 2007; hydraulic failure 14 laps from home in Malaysia and an oil leak at the US Grand Prix five laps from the finish (although classified 16th), where he was on course for sixth place. He had started the race 14th having "glazed" his brakes during qualifying, therefore damaging his confidence. An electronics glitch also put him out of the Japanese Grand Prix.

During the first half of 2007 season, Rosberg saw his teammate Alexander Wurz score more points, but later in the season Rosberg passed Wurz in world championship points, eventually more than quadrupling his 2006 points haul with 20 points.

On 29 October 2009 Rosberg announced he was leaving the Williams team at the end of the season. He commented that Williams "have really supported my career over the years and Id like to say a big thank you to them. However, Im not sure they can win races at the moment and I would like to". On 16 November 2009, Brawn GP was bought by Mercedes and re-branded as Mercedes GP for the 2010 Formula One season. On 23 November 2009, Rosberg was announced as the teams first driver. On 23 December 2009, Michael Schumacher was announced as Rosbergs team-mate, and was given Rosbergs car number (3) because of superstitious reasons. Despite much hype concerning Schumachers comeback, Rosberg managed to successfully out-qualify and out-race his team mate at most races. In Malaysia, Rosberg achieved his first front row grid start, having qualified second in a qualifying session disrupted by rain; again out-qualifying Schumacher. He eventually finished third in the race; Mercedess first podium as a works team since their comeback. His third place at the Chinese Grand Prix provided Rosberg with his second podium in succession, and he momentarily moved into second place in the drivers standings.

He finished seventh at Monaco, fifth in Turkey and sixth in Canada, but only tenth in the European Grand Prix. However, in the British Grand Prix, Rosberg managed a podium finish in third place by holding off Alonso and then Button. But at the German Grand Prix, Mercedes were once again off the pace, and Rosberg could only finish eighth, ahead of teammate Schumacher. Hungary looked more promising, but he lost a wheel while exiting his pit stop and was forced to retire from a point-scoring position. His race at Spa was more successful, and a race-long duel with Schumacher left Rosberg narrowly ahead of his team mate in sixth. The Italian Grand Prix yielded another consistent finish in fifth, achieved mainly by passing both Red Bulls at the start, and took another fifth place finish in Singapore.

However, he was hit by bad luck in Japan, when under pressure from Schumacher, a wheel detached itself from his car and put Rosberg into the wall. At the inaugural Korean Grand Prix he was even more unfortunate, when while running a strong fourth, he retired from the race after being collected by Mark Webber. Webber had spun into the wall and momentum took him back onto the racing line and left Rosberg with nowhere to go and the two collided. The race at Interlagos was more positive, with Rosberg finishing sixth, despite three pit stops, two of which were taken under safety car conditions which minimised a loss of track position. The following week in Abu Dhabi, Rosberg again pitted under the safety car and this allowed him to finish fourth, a result that secured him seventh in the Drivers Championship. Rosberg finished 16 of the seasons 19 races, of which 15 were points-scoring finishes.

In the season-opening Australian Grand Prix, Rosberg won the race by over 20 seconds, having started from third (his father Keke had won the first Formula One Australian Grand Prix in 1985 in Adelaide). Daniel Ricciardo finished the race second, but was later disqualified for a fuel infringement, promoting Kevin Magnussen to second and his team mate Jenson Button to third. Rosbergs team-mate Lewis Hamilton retired due to an engine problem after starting on pole. In Malaysia he finished 2nd, 17 seconds behind teammate Hamilton, but in front of Sebastian Vettel to give Mercedes-Benz their first 1–2 since Italy in 1955. In Bahrain Rosberg took pole position but lost out to Hamilton at the start of the race, and eventually finished second to his team-mate, despite putting him under pressure numerous times. Rosberg said: "I thought Id got him about nine times but they didnt work" and said the race was "a day for the sport" considering the criticism that Formula One has had in 2014. In China he started fourth but fell back to sixth in the opening lap, however fought hard to finish second ahead of Fernando Alonso.

As the season moved to Europe for the Spanish Grand Prix, Rosberg was pipped to pole by Hamilton despite being quicker for most of the weekend until the final lap. Rosberg stayed with Hamilton for the whole race but could not get through finishing one second behind him meaning Hamilton took the championship lead for the first time in 2014. In Monaco Rosberg took his second pole in as many years, however his pole was controversial as he went down the escape road at the Mirabeau corner causing yellow flags making Hamilton abort his final fast lap. Rosberg had set the fastest lap of Q3 earlier on in the session. After the qualifying session concluded, Rosberg was investigated by the stewards. The stewards examined video and telemetry data from the team and the FIA and determined that it could find no evidence of any offence related to the fifth turn incident. Hamilton implied that he thought Rosberg had made the mistake deliberately to secure pole but the stewards saw it as an accidental racing incident. Rosberg then went on to lead every lap to win the race by around 10 seconds ahead of Hamilton. This win gave Rosberg the championship lead again and was later extended by 18 points in Canada after Hamilton failed to finish, compared to Rosberg who finished 2nd in a limping car with no recovery system. His first place in the Austrian Grand Prix saw his lead extended by a further 7 points over his team mate Lewis Hamilton, who placed second in the race. As of the end of the Austrian Grand Prix, Rosberg has 165 points, with his team mate and nearest rival Lewis Hamilton having 136 points.
