A job advert has gone out for the 26.5 hour working week, promising a salary north of £100k.
The father-of-three from Sheffield said: "I've never ever been motivated by money in any job that I've ever taken, and even though I've loved working at BBC Breakfast and everybody who works on the show, this is a fantastic opportunity to work with a brilliant team at Channel 5.
"And also go and make some programmes outside of news,” he added.
It comes after Dan told viewers last week that his last day on the show would be on Tuesday, May 17.
Asked by co-presenter Ms Nugent if he would be having a leaving do, he said: “As you very well know I like other people’s parties – I’m always slightly awkward when it’s something to do with me. I’ll leave it for you to organise.
Mr Walker, who was a contestant on Strictly Come Dancing this year, is leaving to take up a new job with Channel 5 News, where he will replace Sian Williams on 5 News.
Dan moved to Sheffield as a student, and has stayed in the city ever since. He has in the past spoken of how he loves living in the city, close to the Peak District.
