Mouneimne gets permanent posting at Warriors
The South African, who has a wealth of experience at the top level and has been working with Stade Francais in Paris, has been assisting as a consultant at Sixways.
He will now make a permanent move to the English club at the start of next season.
Simon Cross now becomes breakdown coach, while the arrival of Mouneimne sees him reunited with former colleague Gary Gold – whom he spent time at Super Rugby outfit the Sharks.
Mouneimne began his coaching career back in 2006 with South Africa's Sevens team in the World Series, before moving to the Stormers in 2008.
He also worked with Western Province in the Currie Cup in 2009 and 2010.
In 2010, Mouneimne moved onto the international stage as Italian defence coch – where the Azzurri beat defending champions France in 2011 for the first time ever in the Six Nations.
He had a stint with the Southern Kings in 2013.
A spell at Edinburgh followed as he helped them reach the European Challenge Cup Final in 2015 before a stint at Lyon in the Top 14.
He returned to South Africa for a stint at the Eastern Province Kings, before he joined the Sharks at the start of the 2016 season.
Moumeine then asked for an early release from his contract at the Sharks to move to France.
In his short time working alongside Gold at the Durban-based Sharks, Mouneimne helped them reach the quarterfinals of last year's Super Rugby – as they boasted the fewest points conceded and the second-fewest tries conceded out of all 18 teams in the competition.
"Omar is someone I've worked closely with at the Sharks and has a great deal of knowledge and experience at the top level within the game," Warriors Director of Rugby Gold said.
"His defensive structures will certainly be of benefit to us and his efforts at Sharks resulted in the team being one of the top defensive sides in the 2016 Super Rugby competition."
Mouneimne added: "I'm looking forward to getting started at Warriors and to help Gary and his team push up the Premiership table.
"It's an exciting opportunity to work alongside a talented young squad."
