He has also been a first-team coach and assistant manager at Stevenage, Preston North End, Newport County and Burton Albion.

[5] He always wanted to be a footballer since watching the 1978 FIFA World Cup in which the Tunisian team made their first appearance in the finals.

[4] Maamria has described it as one of the "proudest moments" of his career, owing this to the match being played in front of the Tunisian President, as well as the stadium being full of spectators.

[1] While playing for AS Marsa in an away match against Étoile Sportive du Sahel, a tourist resort in the north of Tunisia, he was watched by Burnley's chief scout at the time, Brian Miller, who was on holiday.

[5] After scoring in a reserve match against Bradford City, he earned a short-term contract at Burnley, although he failed to make a first-team appearance for the club after he suffered a broken leg.

[13] He joined Leigh RMI in August 2001,[14] combining playing for the club with a coaching job at his former employers, Burnley.

[21] After making 17 appearances and scoring five goals with Southport,[13] he joined Rushden on a one-and-a-half year on a free transfer in January.

[24][25] At the time of his appointment, Northwich were in last place in the Conference Premier having lost 15 of their opening 17 matches to start the season, drawing the other two, and were 15 points adrift of safety.

I said to the players there are two things we can do: we can either make excuses and say that we have had financial problems and lie down and die or we can go out and perform and try and beat the teams in front of us".

[25] In his second game in charge, Northwich won their first match of the season, a 3–1 away victory at Southport in the FA Cup on 27 October 2007.

[26] Two victories within the space of three days in April 2008,[26] the latter a 2–1 away win against former club Stevenage, meant that Northwich had secured their Conference Premier status for another year.

[33] Maamria was placed on gardening leave for "reasons still unconfirmed" in September 2008,[34] and was subsequently sacked by Northwich "following an internal investigation surrounding his suspension" on 23 October 2008.

[38] During the season, he was also included as part of the playing squad, helping the club to its first ever Herts Senior Cup title in April 2009, scoring twice in the final against Cheshunt in a 2–1 victory.

[40] Maamria earned his first piece of silverware as first-team coach when the club won the FA Trophy at Wembley Stadium, defeating York City 2–0 in the final on 9 May 2009.

[44] That season, following a shortage of players for Stevenage's match against Lincoln City in September 2010, Maamria was assigned the number 27 shirt and was as an unused substitute in the club's 1–0 victory.

[46] Despite a squad overhaul, the coaching team did not replicate the success that they had experienced at Stevenage, and he left the club in February 2013 after Westley was sacked.

[47] A month later, Maamria rejoined Stevenage as assistant manager to Westley, who had returned for a third spell in-charge of the Hertfordshire club.

[48][49] During the 2014–15 season, Stevenage made the League Two play-offs, losing to Southend United over two legs at the semi-final stage in May 2015.

[23] Two months into the 2016–17 season, on 10 October 2016, Maamria was once again appointed as assistant manager to Westley, this time at League Two club Newport County.

[53] Maamria was appointed manager of National League club Southport on 19 November 2015, his first managerial role since keeping Northwich Victoria in the same division seven years earlier.

[54] Southport were sitting in the relegation zone at the time of his appointment having won three matches out of 20 during the opening months of the season, and were eight points adrift of safety.

[58] After leaving his coaching role at Newport, Maamria stated he had "plenty of chances to get back into football", but was waiting for the right opportunity.

[60] Maamria's first game as manager of Nuneaton was a 2–1 away defeat to FC United of Manchester on the same day his appointment was announced.

[70] On 8 January 2021, Maamaria was appointed as assistant manager at League One Club Burton Albion to Jimmy Floyd Hasselbaink.

[4] During his time playing at Leigh RMI, Maamria also worked as an Ethnic Minorities Development Officer at Turf Moor.
