Lynn will link up with Wales after attempting to win a third successive Premiership Women’s Rugby title with Gloucester-Hartpury on 16 March, with his side going up against Saracens.
He then has less than a week to prepare Wales for their Women’s Six Nations opener against Scotland in Edinburgh on 22 March.
Jones hopes Lynn’s club success will transfer to the international stage along with his attacking style of play.
“It’s pretty exciting to have Shaun in because I know what he can create, a good environment where hopefully we can thrive and play our best rugby under him,” she said.
“He’s a very excited, proud Welshman.”
With Wales finishing bottom of last year’s championship, Jones said she will not be measuring this year’s success by their table position.
“I think after the year we’ve had, personally I’d like to see my players and my team just smile in the jersey and enjoy playing Welsh rugby,” she said.
“Just finding that love again in a Welsh jersey would be a massive win for us.”
