Slow left-arm unorthodox bowler Lintott trained with the Bears ahead of the 2020 season and won a contract for last year’s Vitality Blast campaign, where he impressed with 10 wickets in nine games at an average of 18.9 and economy rate of just 6.3.
Lintott will still play for, and captain, Clevedon during the 2021 season when his county schedule allows.
"It’s a pretty surreal feeling to sign my first full time contract with Warwickshire," said Lintott. "It’s a special club and an incredible place to play cricket, I can’t wait to get out there this summer’
"I owe huge thanks to Clevedon - this will be my seventh year with the club and the support they have given me throughout my time at the club has helped create this opportunity for me.
"It’s a great club, with great people. I look forward to representing the club this summer again and seeing all the locals coming up to support us"
Warwickshire’s Director of Cricket, Paul Farbrace, said: “Jake made a fantastic impression during our Vitality Blast campaign in 2020 and we’re thrilled to secure his immediate future with the Club.
“Slow left-arm unorthodox bowlers are not easy to discover and Jake provides another dimension to our spin bowling attack, alongside slow left-arm orthodox Danny Briggs and off-spinner Alex Thomson.”
