The Scot comes in following the departure of Dave Ward in April, after four years as head coach.
The Bears finished fourth last season to reach their fourth successive PWR semi-final, but were beaten by Gloucester-Hartpury in what proved to be Ward’s final match.
He also took the team to their first final in 2024, where they were also beaten by Gloucester-Hartpury.
Lawson said he planned to work hard and be relentless to aim to bring success to the club.
“From the moment I spoke with Daisie Mayes [general manager] and Pat Lam [director of rugby] it was clear that the vision for the women’s programme and the aligned approach across the whole club was something I really wanted to be a part of,” Lawson said.
“I’ve loved my time with Scottish Rugby and will always be grateful for the experiences and relationships I’ve built there, which I’ll continue to value moving forward.
“But this was an exciting opportunity I simply couldn’t resist.”
The club have not disclosed the length of Lawson’s contract.
“His vast coaching and playing experience across a range of different environments and levels, together with his passion for the role, understanding of the club vision and focus on player development and winning impressed us during the interview process,” Lam said.
