The Belgian coach has a rich pedigree which includes an invitation to train Real Madrid from Jose Mourinho and scouting duties for his country.
Chris Powell's three-year reign at Charlton came to an abrupt end yesterday as the struggling Addicks decided to act in an effort to stave off the threat of relegation.
His replacement was named earlier, but Jose Riga is not a name all too familiar with the English game, having harnessed his managerial abilities in his native Belgium.
A relative unknown he may be, but it should not belittle his talents, especially for a man who has some top-level experience in the game.
Here are five facts about the man tasked with steering his new club away from the bottom of the Championship.
1) King of promotions
Riga has an outstanding record of securing promotion from the lower rungs of the Belgium footballing ladder, having led two different sides to the next step up.
In his spell as RCS Vise manager, he masterminded two promotions and helped RAEC Mons reach the top flight.
2) Emphasis on youth
After a spell in charge at Standard Liege, which failed to yield much more than a final-eight Europa League berth, he took up a role in Qatar bringing through the latest generation of youngsters in time for the 2022 World Cup in the country.
He holds a UEFA Pro License and leads coaching courses for the Belgian FA. His most latest venture has seen him work with AC Milan's youth team, utilising the CogiTraining technique he was responsible for initiating.
3) His coaching inspirations
Riga has closely studied the tactics of Gerard Houllier, Eric Gerets and Trond Sollied, who have all had a major bearing on the way the 56-year-old likes to play the game.
His CogiTraining technique is based on 'speed of vision, speed of decision-making and speed of execution'.
4) Invitation from Mourinho
The Chelsea manager was so impressed with the methods Riga was helping to implement in the game that he invited the Belgian along to one of his former Real Madrid side's training sessions.
It remains to be seen whether such visionary tactics will come in handy when trying to beat relegation to League One, but Charlton definitely have someone highly rated in their hotseat now.
5) Computer genius
Riga does not just boast an excellent cv for his work in football, however.
He holds a degree in computer sciences and 20 years' working within the IT sector of several insurance firms, proving he is no one-trick pony.
