Rory Teague has been appointed as England's full-time skills coach having held the role on a temporary basis during the November Series.
The former England U20 backs and attack coach helped guide the side to glory at the World Rugby Championship in the summer.
Teague joins forwards coach Steve Borthwick, scrum coach Neal Hatley and defence coach Paul Gustard in England’s backroom team.
"Rory's come up from the 20's and will doing skills during the Six Nations, so he'll be full-time with us," head coach Eddie Jones told the RFU website.
"He's a good, young coach. He's inquisitive, curious, wants to get better and therefore he can play a key role for us in improving the skills of the players."
Teague had playing spells at Gloucester, Bristol as well as Grenoble and began coaching at Harrow School where he guided Maro Itoje from a young age, before moving to Wasps and then Saracens as an academy coach.
He joined England before last year’s U20- ix Nations and his cousin is former England and British and Irish Lion Mike Teague.
England open their Six Nations campaign against France on 4 February.
