Langley, 30, is delighted to be signing for the Eagles for the 2015 season, after a 2014 campaign with Hull KR which was curtailed by injury.
“I’ve met with Tubbs [Eagles coach Mark Aston] a few times and had a couple of really good conversations with him. It’s a new challenge for me and I’m really excited to get going,” he said.
“When I was weighing up my options I spoke to a few of the Sheffield lads and none of them had a bad word to say about the club.
“It makes it easier when you have friends who are already at the club. You get the enjoyment aspect which is a big part of why I play rugby.
“The drive that the club has got behind it at this moment in time, looking to progress over the next few years with the new stadium and everything else, it just seemed like a no brainer for me.”
Langley will also be involved in the coaching set-up at Sheffield, something he admits helped draw him to the club.
He is also excited by the challenges posed by the league restructure next season.
“I’m going to be playing first and foremost and I want to play on for as many years as possible,” he added.
“Helping on the coaching side of things is really appealing to me at this stage. I feel like I have a lot to offer having worked under some great coaches during my career.
“You learn little bits from each one and hopefully I can part with some of that wisdom myself.
“It’s going to be a really good competition next year. All the teams are strengthening; I think they realise it’s going to be a step up in class from what it has been.
“It’s going to be tough. The Championship has been close this year and I think there will be a few teams fighting it out for those top spots.
“There are going to be no pushovers and no easy games; I’m really looking forward to getting stuck into it.”
Sheffield head coach Mark Aston is optimistic that Langley can play a major role in the Steel City.
“We are delighted that Jamie has chosen to join us here at the Eagles,” said Aston.
“I am looking forward to working with him both as a player and as a coach, we have a relatively young forward pack and his knowledge and experience will be invaluable to them.
“I am sure that Jamie will quickly become a fans favourite and build on the reputation he has already gained from his experiences in both Super League and International Rugby.”
