Mulder was born and raised in Pannerden, Gelderland, the Netherlands, a small village close to the German border between Arnhem and Zevenaar. Mulder's father was a talented goalkeeper, making his first team debut at the age of 16 on the second highest amateur level. Mulder has two older brothers.
Mulder started playing football at local Pannerden club R.K.P.S.C.. At the age of ten, Mulder made the switch from field player to goalkeeper. After being a goalkeeper for one year, Mulder received his first invitation for the KNVB district team: "From that moment on I realized I had talent. I really enjoyed it as well, diving in the mud, loved it." 
When Mulder went to secondary school around the age of 12, the goalkeeper joined the Vitesse youth academy, a professional Eredivisie club from Arnhem. After playing for Vitesse for three seasons, Mulder was asked to join the Feyenoord youth academy. At Feyenoord, Mulder was seen as one of the biggest goalkeeping talents. Feyenoord's former goalkeeping coach Pim Doesburg predicted Mulder to be the first goalkeeper to reach Feyenoord's first team coming directly from the Feyenoord youth academy since Joop Hiele in the late seventies.
Small steps (2006–2008)
In November 2006, at the age of 17, Mulder was invited to Feyenoord's first team squad by Feyenoord coach Erwin Koeman. As the reserve goalkeepers Patrick Lodewijks and Sherif Ekramy were both facing injuries, the teenager was Henk Timmer's first stand-in. Mulder was on the bench for over ten matches during the season 2006–07, but didn't make his official first team debut. In January 2007, Mulder was one of the few talents to join the first team on training camp in Belek, Turkey, but returned to the Feyenoord U19 squad afterwards.
On 3 June 2007, Feyenoord announced Mulder was officially promoted to Feyenoord's first team squad for the season 2007–08 and extended Mulder's contract until summer 2011 on 28 September 2007. As Patrick Lodewijks retired, Mulder became third goalkeeper behind Henk Timmer and Sherif Ekramy. Due to injuries of the first two goalkeepers, Mulder made his official Eredivisie debut on 2 December 2007, in the home match against Heracles Almelo (6–0).
Loan spell (2008–2009)
To gain experience, Mulder joined Excelsior on loan for the season 2008–09 under manager Ton Lokhoff. Excelsior just relegated to the Eerste Divisie and was in need of a first team goalkeeper when Ronald Graafland left the club to join Vitesse. On 8 August 2008, Mulder made his debut for the Excelsior in a 1–0 loss against Telstar. On 6 March 2009, Mulder received a straight red card, just a minutes before half-time, for a professional foul in the penalty box, resulting a penalty for FC Oss. After being sent off, Arjan van Dijk replaced him in goal. van Dijk couldn't save the penalty to allow FC Oss scored the second goal in the match. The match finished with FC Oss beating Excelsior 3–1 and 3 penalties in the match (2 Oss and 1 Excelsior). After a 3 match ban because of his sending off, Mulder made his return in goal on 27 March 2009 against SC Cambuur in a 1–1 draw. At Excelsior, Mulder played 36 matches for the third club from Rotterdam and finished on a fifth place in the Eerste Divisie. His performance was strong at Excelsior that he was only player in the Eerste Divisie selected by Johan Neeskens for the Netherlands B Squad.
Back at Feyenoord (2009–present)
When Feyenoord decided not to renew first team goalkeeper Henk Timmer's contract, Mulder returned to Feyenoord for the season 2009–10. During pre-season, Mulder had to battle with reserve goalkeeper Rob van Dijk and Feyenoord U19's Darley Ramon Torres for a regular place under the bar.
Mulder was close to another season loan spell at Excelsior when Feyenoord decided to test the Slovak goalkeeper Kamil Čontofalský. Mulder trained with the Excelsior squad for a week, but returned to Feyenoord when Čontofalský's trial was ended. However, Mulder pulled a muscle during a training session, causing him to be sidelined for over four weeks. After his recovery, Mulder remained at Feyenoord, but had to be satisfied with a role as reserve goalkeeper. Following Rob Van Dijk release becoming a free agent (then signing for FC Utrecht on a free transfer), Mulder battle with Darley, Kostas Lambrou and Ronald Graafland to become Feyenoord first choice goalkeeper. Mulder began in the starting line-up in goal and established himself in the starting eleven under new manager Ronald Koeman. In his first season Mulder said in the interview: "Only when I keep a very good season, I really feel the undisputed number 1. Although there is still no."
On 14 March 2012, Feyenoord technical director Martin van Geel says the club has plan to offer goalkeeper Erwin Mulder a new contract at Feyenoord as they look to continue developing the youngster and also says he hope Mulder will accept a new deal.
On 7 May 2012, Mulder was named in the provisional list of 36 players for the Euro 2012 tournament, one of nine uncapped players to be chosen by Netherlands manager Bert van Marwijk as part of the preliminary squad.
