The British royal family is looking for a £50,000 ($72,000) per year social media specialist to run The Queen's Twitter and Facebook accounts.

"Whether you're covering a state visit, award ceremony or royal engagement, you'll make sure our digital channels consistently spark interest and reach a range of audiences," said the job specification for "the Head of Digital Engagement".

The advert perhaps did not come as a surprise to many, as Queen Elizabeth II, who turns 90 on Thursday, is known as a social media-savvy senior citizen.

She sent her first tweet in 2014 and her majesty's own website was launched as early as 1997.

Earlier this month, The Queen backed a major upgrade of the Buckingham Palace official website, with more emphasis on social media.

The British Monarchy Twitter account already has over 2 million followers, Kensington Palace has 628,000 on Twitter and Clarence House has over 500,000 on Twitter.

But the job advert says "it's about never standing still and finding new ways to maintain The Queen's presence in the public eye and on the world stage. This is what makes working for the Royal Household exceptional".

The person who gets the job must have experience "managing high profile websites" and be "comfortable developing strategy and managing wide-reaching projects".

As for the benefits package, there will be "a 15% employer contribution pension scheme and 33 days annual leave, including bank holidays."
