Goulden, formally of Wasps FC, has made a total 28 appearances and scored 167 points in the Premiership since 2017, proving she will be a real asset to the Lightning backline adding another dimension to their attacking game.
Whilst playing for Lightning, Goulden will also balance her full time career as a lawyer.
Speaking about the move she said:
“I am stoked to be a part of this environment, training alongside and learning from some of the best there is.
"Lightning play innovative and exciting rugby so I'm looking forward to getting stuck in!”
Commenting on Goulden joining the Lightning set-up, Director of Rugby Rhys Edwards added:
“Watching Lizzie play a few years back in the national academy game, she was somebody that really stood out. She has been running the show for Wasps for the past few years and her kicking game is something that has really stood out when we have played against them in the past.
"For Lizzie to choose to move to us is a sign of how ambitious we are as a club, but also how exciting the brand of rugby we are trying to play. Having Lizzie on board will be brilliant as she fits into the way we want to play and adds a competitive edge to the squad.”
