Gryba was selected in the third round, 68th overall by the Ottawa Senators during the 2006 NHL Entry Draft. Prior to turning professional, Gryba attended Boston University, where he played four seasons of NCAA Division I ice hockey in the Hockey East conference with the Terriers ice hockey team, winning a NCAA title with the team. During the 2009–10 NCAA season, he tied the school record for most penalty minutes served. On March 31, 2010, the Ottawa Senators signed Gryba to a two-year, entry-level contract. On February 16, 2013, he made his NHL debut, playing for Ottawa in Toronto against the Toronto Maple Leafs. Gryba earned his first career NHL point, an assist, against the New York Islanders on February 19, 2013, and scored his first career NHL goal against the Tampa Bay Lightning on March 23, 2013. On May 2, 2013, in his first Stanley Cup playoff game against the Montreal Canadiens, Gryba delivered a questionable, open-ice hit to Canadiens' forward Lars Eller as Eller received a pass from Raphael Diaz. The hit caused Eller's face to strike the ice, leaving him bleeding and motionless on the ice and later carried off via stretcher. Though there was some question as to whether or not the hit was illegal, Gryba was subsequently suspended for two games when the NHL deemed that Eller's head had been the principal point of contact. On June 26, 2014, Gryba signed a two-year contract extension with the Senators, valued at $2.5 million.
On June 27, 2015, on the second day of the 2015 NHL Entry Draft, Gryba was traded by the Senators to the Edmonton Oilers in exchange for Travis Ewanyk and the 107th pick in the fourth round. After appearing in 53 games for the club, the Oilers chose not to re-sign Gryba, making him an unrestricted free agent. However, Gryba signed a one-year, two-way contract on October 12, 2016, after attending the team's camp on a professional tryout. On December 31, 2017, Gryba cleared waivers and was assigned to the Oilers' American Hockey League affiliate, the Bakersfield Condors. On June 21, 2018, the Oilers placed Gryba on unconditional waivers for the purpose of a buyout.
On July 1, 2018, the opening day of free agency, Gryba was signed by the New Jersey Devils on a one-year, two-way $700,000 contract. On September 22, 2019, Gryba announced his retirement on his Twitter, after being released from his professional tryout with the Calgary Flames.
