England's narrow semi-final loss to hosts India in the T20 World Cup on Thursday brought an action-packed period across both white and red-ball cricket to an end.
McCullum faced scrutiny over his position following a disastrous Ashes campaign, which only heightened after news filtered out regarding off-field incidents, but the 44-year-old expressed his desire to continue on Thursday and the Press Association understands that will be the case.
Speaking after a seven-run loss to India in an overall positive World Cup campaign, McCullum told the BBC: "I'm enjoying the role across all formats and I'd love to carry that on.
"I'm not saying it's a great job because it's a lark, I'm saying it's a great job because I'm working with some of the most talented players in the world with an organisation that is very well structured, well run and well supported by the fans.
"Yes, we've missed some opportunities, but I think this team has a real opportunity over the coming years to continue to improve and hopefully finish what we started. I'd love to be a part of that."
While England and Wales Cricket Board bosses are still conducting a formal review into what went wrong in Australia, McCullum is expected to remain in post and get the chance to lead the Test team into a home Ashes in 2027.
McCullum received strong support from white-ball captain Harry Brook following defeat in Mumbai.
Brook, who was given the limited-over reigns by McCullum, has also endured a tricky few months and found himself in the firing line for an incident in a nightclub in New Zealand ahead of the winter Ashes.
"I've said plenty of times he's the best head coach I've ever had," Brook said.
"The things he's done over the four years since he took over has changed English cricket for hopefully the best. One hundred and 25 per cent, he should stay on."
