We are Optiver, an international trading company, headquartered in Amsterdam. With more than 700 colleagues across four continents we constantly offer fair and highly competitive prices for the buying and selling of stocks, bonds, options, futures, ETF’s et cetera. It is called ‘market making’. We build markets and provide liquidity to international exchanges in Europe, the US and Asia Pacific.

We make financial markets fair, open and reliable. We do not only trade when we feel like it. Not only when our outlook is bright, but 24 hours a day. Whichever way the markets go, we are there, always at our own risk, using our own capital. ‘Value the difference’ sums it up perfectly. It explains in a nutshell what we do every day. It also invites you to explore how we do our job differently.

We want to be the best trading firm in the world and therefore we need the most advanced technology, trading software and connections to the market. In short, we need the best IT-professionals to develop, optimise and support our tools. We aim to be unrivalled in our industry, by being talented, creative and result-driven. And it doesn’t matter how we dress or what we believe in, as long as we exceed our and each other’s expectations.
