The post is being advertised at the 125-year-old Peebles Hydro.
General Manager Patrick Diack said he could not think of a better time of year to recruit for the post.
He said Blue Monday on 18 January, which is meant to be the gloomiest day of the year, might inspire some "amazing applicants" for the "energetic and creative" job.
The successful applicant will take the lead on "all the fun things" to do at the hotel, including running its Bike Zone and creating activities for its Kids Club.
"The position is certainly not a desk job, this is a hands-on position for someone who gets a kick out of bringing a smile to the faces of people of all ages and is adept at connecting with people," Mr Diack said.

The "large scale public order incident" occurred at Stapleford Abbotts Golf Club, Essex, on Tuesday night.
Police were called to a "disagreement" at the party, attended by about 100 people, and "dispersed" those involved.
Afterwards, officers posted photos of themselves removing the cakes, which they said were "donated", and took them to homeless shelters.
Essex Police and a police helicopter were called after trouble broke out at the event at the golf club, near Epping, at about 22:00 GMT.

Rory O'Keeffe, assistant manager at the club, said "about 100 Irish Gypsies" turned up to the party, which he understood was to celebrate a confirmation.
Insp Rob Brettell, from Essex Police, tweeted to say "lots of damage" had been caused at the club, and some thefts had also been reported.
He later wrote on Twitter to say "a number of cakes were donated to our team tonight".
He included photographs of a fairytale castle cake and a number of smaller cakes decorated to look like Disney-style princesses.
These, he said, were being taken to homeless shelters and mother and baby units.
Mr O'Keeffe said "no real damage" was caused to the club, but staff were still "cleaning up the mess and dirt" on Wednesday morning.
"And I think a few partygoers are still sleeping off their hangovers in a trailer in the car park," he added.
Essex Police said no-one had been arrested in connection with the incident, but they were "continuing to monitor the situation".
The golf club said it was open for business as usual.

The prime minister has invited his German counterpart for a working dinner at his country residence, Chequers.
The wide-ranging talks also cover the threat of so-called Islamic State, the situation in Iraq and Ukraine.
Mr Cameron earlier welcomed Estonian Prime Minister Taavi Roivas to Downing Street for bilateral talks.
The meetings with his European counterparts come on the day that a new campaign to get the UK to leave the European Union is being launched ahead of the in-out referendum, promised by 2017.
Vote Leave, made up of Conservative, Labour and UKIP MPs and donors, says it wants to negotiate a new deal based on free trade and friendly co-operation.
Mr Cameron has pledged to reform Britain's relationship with the EU before holding a vote on membership and will discuss his aims with Mrs Merkel as part of his continuing negotiations with European leaders.
The pair will also discuss the migrant crisis affecting Europe, as European countries continue to struggle to cope with the influx of people reaching the continent from the Middle East and Africa.
Russia's bombing campaign in Syria is also likely to be raised at the meeting, as concerns grow about Moscow's involvement in the war-torn country - as well as its backing for separatist rebels in eastern Ukraine.
During talks with the PM at Downing Street, Estonian Prime Minister Mr Roivas thanked Mr Cameron for the UK's commitment to send 100 British military personnel to the Baltic region.
Defence Secretary Michael Fallon has said the troops will deter Russian aggression beyond Ukraine and reassure eastern European Nato members.
Speaking at a press conference on Friday, Mr Fallon - who held talks with his US counterpart Ash Carter in London - said the UK government was committed to building support for air strikes against IS in Syria.
He said Russia's military action had made a "grave situation even worse".
The UK is currently involved in coalition air strikes against IS targets in Iraq but not Syria, after Parliament voted against the move in 2013.
