Steven Lawrie, who played for Scotland at under-19 and under-21 levels, joined Edinburgh Gunners as an apprentice in 2005 and moved on to a full contract in summer 2007. His debut for Edinburgh was as a replacement in the Celtic League victory against Leinster at Donnybrook in November that year. Another replacement appearance followed in the next game (against Glasgow), but he had to wait more than a year for his first start for Edinburgh: coincidentally, that also was against Leinster at Donnybrook in the Heineken Cup match in January 2006. Steve captained the Edinburgh under-18, under-19 and under-20 teams who won their respective district championships in successive years (2002 to 2004), and he played for Scotland under-19 in season 2002-2003.

He made his Scotland A debut in the 25-0 win over USA Eagles at Netherdale in November 2010, and came off the bench in the 11-3 success against Italy A in February 2011.
