Alex Meechan was an Associate Schoolboy at Norwich in the 1994/95 season. He moved to Swindon where he made his league debut against Wolves in the autumn of 1997.

Alex then moved on to Bristol City where his impressive form for their Under 21 team led to a four-year contract. However he made just 13 appearances, scoring 4 goals by the end of the 1999/2000 season and moved in the summer of 2000 on loan to Football Conference side Forest Green Rovers. Rovers were keen to sign Alex but he opted to return to Ashton Gate in October 2000 and fight for a first team place. This apparently was not likely as Alex was to be found a few days later playing on trial with Plymouth reserves in a 2-1 win over Swansea. Alex also had a trial in November with Notts County but did not impress their manager Jocky Scott.

After a brief loan period with Yeovil, Alex signed permanently for Forest Green in the last days of 2000. He was Forest Green's leading scorer for the following two seasons.

In June 2003, Alex turned down the offer of a new deal with Forest Green and on 10th June 2003, signed a two year deal with Conference giants Dagenham & Redbridge for a nominal fee. However Alex found it hard to settle, and scored just twice in 15 appearances. He was placed on the transfer list on 30th October 2003. Forest Green manager Colin Addision has already expressed an interest in bringing Alex back to Forest Green. This materialised on 25th November 2003 when Alex signed a three month loan deal with Rovers. This was later made permanent.

Alex spent most of the 2004 pre-season with Luton but towards the end of July 2004, he trialled with Barnet, scoring twice against St Albans City in a pre-season friendly. Although offered a contract by the Bees, this was not viable as he was living up north. He joined Leigh RMI on 12th August 2004 but his stay didn't last long as RMI released him on 6th November 2004. Within a week though, he had signed for Halifax on a short-term contract. Released at the end of the 2004/5 season, he was linked with a move to Barrow towards the end of June 2005. He later trialled with Forest Green Rovers in mid-July 2005 and was rewarded with a one year contract.

Seeking a move closer to his Liverpool home Alex joined Chester City at the end of January 2007 but was released in May 2007. He joined York City on 11th July 2007. He was loaned to Stalybridge Celtic on 9th November 2007.

He returned to the Conference National after joining Altrincham in July 2008. On 27th March 2009, Meechan had his contract canceled by mutual consent and immediatally rejoined former club Stalybridge Celtic later that day. On 9th July, Meechan joined Tameside rivals Droylsden. At the end of the season Meechan moved to fellow Conference North side AFC Telford United. After earning promotion to the Conference National through the play-offs, Meechan agreed a new one-year deal with the club for the 2011–12 season. In the 2011–12 season he went on a 1 month loan spell at Harrogate Town where he scored on his debut. He then joined Harrogate permanently. Meechan was offered a new contract with the Conference North club for the 2012-13 season in May 2012.

In October 2012, Meechan left Harrogate Town to join Conference North rivals Worcester City. In December 2012 he was however released by Worcester because of budget constraints. He then joined Witton Albion in December 2012 before signing for their rival Colwyn Bay at the beginning of January 2013.

He returned to AFC Telford in March 2013 before joining Barrow as their Assistant Manager on 20th May 2013. When manager Dave Baylis vacated his role on 5th November 2013, Meechan was appointed caretaker manager. AFC chairman Brian Keen has not set any timescale for appointing Bayliss’s replacement, with Meechan having verbally outlined his interest in succeeding the man who brought him to the club during the summer. And he says the club’s board are happy to grant the 33-year-old player/coach’s wish for an interview in which Meechan would target his first permanent number one assignment.

Keen said: “He (Meechan) is a young fella who more or less said to us, ‘look, I'll help the club out and I'll certainly look after things on a professional basis’. He’s obviously interested in the job and he wants an interview. The door is open to anybody. It’s very early days, but Alex has been bubbly, he’s been cooperative, professional and he’s recommended some players who are with us now and you can’t say ‘no’ to him. You've got to give him the opportunity to put his points across, you’ve got to give him the chance to say why he wants the job or if he wants it. He wants to talk.”

On 13th June 2016 he was appointed manager of Bradford Park Avenue after initially arriving at the club as assistant manager. The team failed to win under his leadership and he was moved to manage their Academy.

In 2019 he became joint manager of Stafford Rangers and in 2021 he became assistant manager of AFC Telford United.
