On 10 November 2007, he debuted for the second team of Werder Bremen in the second half of a match, replacing the injured first-choice goalkeeper Nico Pellatz.
In August 2008, Mielitz extended his contract until 2010. His professional debut in the 3. Liga was on 16 August 2008 against Jahn Regensburg. He played 20 times for the side in the 2008–09 season despite competing with Pellatz over a first choice role at the club's reserve.
In October 2008, Mielitz was called up by the Germany U-20 for the first time and made his Germany U-20 debut on 12 October 2008, in a 2–1 loss against Austria U20.
During the 2007–08 season, Mielitz appeared twice as an unused substitute bench for a match against Stuttgart and Bayer Leverkusen. Two seasons later, he made his first appearance with Werder's first team on 3 December 2009 in a Europa League home match against Nacional, filling in for the injured Tim Wiese. Three days later, on 6 December 2009, he debuted in the Bundesliga in a 0–0 away draw against 1. FC Köln, making a good performance throughout the match and kept his first clean sheet on his debut. In February 2010, Mielitz signed a contract extension, keeping him until 2012. Although he was a third-choice goalkeeper for the 2009–10 season, he said he was willing to be patient to fight over a first choice goalkeeper role in the near future. On 30 March 2010, when he made another appearance, starting in goal once again, in a 4–2 win over FC Nürnberg. He suffered a knee injury later in the season. He made a total of three appearances in the 2009–10 season.
Mielitz remained a third-choice goalkeeper behind Wiese and Christian Vander ahead of the 2010–11 season. On 20 October 2010, he made his first appearance in the UEFA Champions League group stage against Twente, coming on for the injured Wiese. Three days later, he started in goal again, making several saves contributing to 4–1 away win against Borussia Mönchengladbach, the club's first of the season. After the match, his performance was praised and he was named Man of the Match. He featured in another Champions League match against Twente on 2 November 2010 which Werder Bremen 2–0 lost. After this, Mielitz remained on the substitute bench for the next two months until coming on as a late substitute following Wiese's sending off in a 3–1 loss against Bayern Munich on 29 January 2011. He appeared three more matches from 5 February 2011 to 19 February 2011 before Wiese's return from suspension. He remained on the substitute bench for the rest of the 2010–11 season. At the end of the season, during which he made the total of 10 appearances for the side, Mielitz signed another contract extension, keeping him until 2013.
Ahead of the 2011–12 season, Mielitz was promoted to a second–choice goalkeeper behind Wiese, taking Vander's place and demoting him to third-choice. After starting the season on the substitute bench, he made his first appearance on 17 September 2011 coming on as a replacement for Wiese, who had been sent off in the early minutes of the match, and conceding a goal in the second–half from Philipp Wollscheid, in a 1–1 draw against 1. FC Nürnberg. While Wiese served a three-match ban until late October, Mielitz played the next three matches and filled in showing very good performances, including in a win over Hertha BSC on 25 September 2011. On 3 December 2011, he started again after Wiese was given a bereavement leave, and conceded four goals, in a 4–1 defeat to Bayern Munich. After suffering short–term injury in January 2012, he was featured in two matches between 17 March 2012 and 24 March 2012 following Wiese's injury. He remained on the substitute bench throughout the 2011–12 season and was limited to a total of 7 appearances for the side. Shortly after the end of the season, he signed another contract extension in May 2012 which would keep him until 2014.
Ahead of the 2012–13 season, Mielitz was expected to be the club's first choice goalkeeper by the club's general manager Klaus Allofs following the departure of Wiese to Hoffenheim. In the LIGA total! Cup 2012, Mielitz was the hero when he made two saves in the penalties shoot-out (one from Bastian Schweinsteiger) in a 4–2 win over Bayern Munich to progress through the final which they beat Borussia Dortmund in a penalty shoot-out again the following day. After the match against Bayern Munich, he said YouTube helped him save a penalty from Schweinsteiger. After starting in goal in the opening game of the season against Borussia Dortmund, he kept his first clean sheet, in a 2–0 win over Hamburg on 1 September 2012. Throughout the 2012–13 season, Mielitz was an ever present goalkeeper for the side, but received criticism from the media and pundits, including Frank Rost for conceding goals and lack of clean sheets, which he kept three times during the season. In response to criticism, Mielitz defended himself, saying: "I make my cause well!" and felt he was treated unfairly. During a 1–1 draw against 1. FSV Mainz 05 on 30 March 2013, he put out his best performance at Werder Bremen, making a lot of saves, to help the side ease their chance to avoid relegation.
In the 2013–14 season, Mielitz continued to remain the club's first choice goalkeeper and started well keeping two clean sheets in the first two league matches against Eintracht Braunschweig and Augsburg. He also kept two more clean sheets while remaining first choice goalkeeper. However, as in the previous season, Mielitz continuously conceded goals on a regular basis, leading Kicker to say that he lacked "charisma, though he seems calm, factual, sometimes a little too pale." Following a 3–2 loss to 1. FSV Mainz on 24 November 2013, he was dropped as a first choice goalkeeper in favour of Raphael Wolf and was placed on the substitute bench for the rest of the season. In response to this, Mielitz said he was disappointed upon learning that he would remain on the substitute bench. He finished the 2013–14 season with 14 appearances.
It was confirmed in April 2014 that Mielitz would not be offered a new contract by the club and was expected to leave the club at the end of the season. Although he did not play against Hertha BC, he made his farewell appearance and confirmed his departure from the club. By the time of his departure, Mielitz was not considered a replacement of Tim Wiese by the Werder Bremen supporters, including the club's former goalkeeper Dieter Burdenski.
Shortly after leaving Werder Bremen, Mielitz was linked a move to SC Freiburg. The move was confirmed on 28 May 2014, as he signed a three–year contract.
With a lack of first team opportunities at SC Freiburg, Mielitz opted to join Greuther Fürth on 11 June 2015, signing a two–year contract. Upon joining the club, he was expected by then-manager Stefan Ruthenbeck, who was appointed one day before he signed for them, to fight for the first-choice goalkeeper role.
Mielitz attended a sports school when he was 13 before going to a different school in Bremen where he graduated despite being absent from class. He revealed that his parents were supportive of his sport choices, having took him to important events and games, but after attending boarding school in Cottbus, he began to live apart from his parents and see them only on weekends. In addition to speaking German, Mielitz also speaks English and Spanish. In July 2015, Mielitz became a father for the first time when his girlfriend gave birth to a baby boy.
With his Greuther Fürth contract running out at the end of the 2016–17 season, Mielitz joined Danish Superliga club SønderjyskE for the new season on a two-year contract with the option of a third in May 2017.
In July 2020, Mielitz joined 3. Liga side FC Viktoria Köln on a free transfer.
