Bromwich, a veteran of 272 games for the Melbourne Storm and 29 Tests for New Zealand, will form a key part of the Dolphins' pack when they enter the competition in 2023.
The 32-year-old has signed a two-year deal with Wayne Bennett's side.
"Jesse will bring a host of good qualities to the Dolphins' inaugural roster, not the least of which will be his exposure at the highest levels of rugby league," said the club's chief executive Terry Reader.

Heidi Klum: It Wasn't 'Easy' for Tom Kaulitz to Get 4 Kids 'All of a Sudden'“He’s amazing,” the former Project Runway host, 48, exclusively told Us Weekly recently while promoting her “Chai Tea With Heidi” dance track with Snoop Dogg and WeddingCake. “I’m sure it’s not easy to step into an immediate family, having all of a sudden four kids and teenagers.

Meanwhile, Penrith's premiership-winning fullback Dylan Edwards has agreed to a new two-year contract extension that will keep him at the club until 2024.
After losing Paul Momirovski (Roosters) and Kurt Capewell (Broncos) this year and with Api Koroisau (Tigers) and Viliame Kikau (Bulldogs) leaving after the 2022 season, the retention of the 26-year-old is a win for the Panthers.
Edwards, who played through the pain of a broken foot during the Panthers' charge to the grand final, made his debut in 2016 and has scored 21 tries in 80 games.
Elsewhere on Friday, the Gold Coast Titans announced a fresh deal for hardworking back-rower Sam McIntyre which guarantees he will stay with the club until the end of the 2023 season.
