The oil and gas consultancy said Mr White would draw on the leadership skills he honed while captaining the Scotland rugby team, to help the firm maintain its competitive edge.
Capped 77 times by Scotland, the highlights of Mr White's career included leading the national team to a famous victory over England in the annual Calcutta Cup clash in 2006.
Mr White said: "I'll be helping to embed lessons from sports that apply equally to the highly competitive business environment we operate in: never give up and keep persevering even when things aren't going well."
With plans to visit Xodus' offices around the world, Mr White, 35, is also looking forward to driving the mentoring scheme the company is developing.
He said: "The mentoring scheme is a real passion of mine. I've had the privilege of having a great mentor and it can bring benefits not only to the work place but also life in general."
Mr White was referring to Tony Westbury, one of his lecturers while studying Sports and Exercise Science at Napier University.
Mr White played for Glasgow until 2003 then spent six years at English Premiership side Sale Sharks. He moved to France's ASM Clermont Auvergne for three years before retiring from rugby and moving into business.
