Internship Programme in Madrid

Join the CoinUnited Internship Programme in Madrid and work alongside our teams on live projects that real traders use every day. Since 2018 we have been building one account that reaches global markets around the clock, across crypto, stocks, indices, forex, commodities and pre-IPO. You will learn by doing, with a dedicated mentor, and strong performers are considered for full-time roles.

This role is based in our Madrid office and forms part of our operations across Europe. You will work to Madrid market hours and support the international order flow connected to the Spain market. Madrid is one of our market facing offices, close to the trading flow that runs across Europe at every hour.
