Finance Intern | Based in Barcelona
Behind every FX transaction Kantox processes, there is a finance function making sure the numbers are right. We are a 200-person fintech handling over $18 billion in client transactions across 75 countries, and our Finance team keeps the engine running. We are looking for an Accounting Intern to join that team in Barcelona and get hands-on experience in a fast-paced, international financial environment.
This is not a shadowing role. From day one, you will be doing real work that the team depends on.
What you will work on
The setup
You will be based in our Barcelona office, working directly within the Finance team. You will get structured onboarding, close support from senior team members, and the opportunity to see how finance operations work inside a profitable, high-growth fintech backed by BNP Paribas.
Who you are
You are currently studying Accounting, Finance, Business, or Economics, and you are looking for an internship where you will actually learn, not just observe. You are comfortable with numbers, disciplined about detail, and the kind of person who flags a problem rather than sits on it.

Nice to have:
