The embattled Labour leader said Britain could "certainly thrive and prosper outside the EU" but the nation needed tariff-free access to European markets.
He said: "We are ready to get on with those neogtiaons straight away and you've got Barry, Keir, Emily, you’ve for very experienced people that will lead those negotiations."
Mr Corbyn also warned against an exit without a deal, which Prime Minister Theresa May has pledged.

Speaking in Basildon, he said: "Britain can certainly thrive and prosper outside the EU but we need tariff-free access to European markets
"Theresa May says no deal is better than a bad deal. Let's be clear: 'no deal' is in fact a bad deal. It is the worst of all deals because it would leave us with World Trade Organisation tariffs and restrictions, instead of the access to European markets we need.
"That would mean slapping tariffs on the goods we export – an extra 10 per cent on cars – with the risk that key manufacturers would leave for the European mainland, taking skilled jobs with them.
"In sector after sector, 'no deal' could prove to be an economic disaster – Theresa May's approach risks a jobs meltdown across Britain."
Emily Thornberry said Labour will not form any coalitions
Mr Corbyn said it was “shameful” that the government had not yet guaranteed the rights of EU citizens in the UK and vowed Labour would straight away.
It comes after Mrs May said Mr Corbyn "wasn't up to the job" to lead Britain's exit from the bloc.

Mr Corbyn also said he was entering the election to win, not form a coalition, which was also echoed by Emily Thornberry, who said: "We are not doing deals, we are not doing coalitions, we are not doing any agreements."
Answering questions following a speech by Mr Corbyn in Basildon, Ms Thornberry was asked whether Labour would be ready to do a coalition deal – or even try to persuade Sinn Fein MPs to attend the House of Commons in order to support them.
She replied: "The truth is we are fighting to win and we are fighting to win with a majority. That's what we are fighting to do.
"If we end up in a position where we are in a minority, we will go ahead and we will put forward a Queen's Speech and a Budget.

"If people want to vote for it, then good. If they don't want to vote for it, they are going to have to go back and speak to their constituents and explain to them why it is that we have a Tory government instead.
"If we are the largest party we go ahead – no deals – with our manifesto, our Budget and our Queen's Speech."
Her comments amount to a firm rejection of Mrs May's repeated claim that a vote for Mr Corbyn's party in next week's election would result in a "coalition of chaos" with Labour propped up by MPs from parties like the Liberal Democrats, Scottish National Party or Greens.
