Technology at Optiver

Since trading on the floor changed to screen-based trading, we constantly need the most advanced technology, trading software and connections to the market. In short, we need the best Engineers to develop, optimize and support our systems and tools. The atmosphere we are working in is fast, but exciting. This makes Tech at Optiver a great challenge whereby expertise, innovation and fun go hand in hand every day.

What you’ll do

During this internship you will be responsible for your own project from day one, guided along the way by a senior developer assigned as your mentor. You will interact closely with our traders and researchers, directly impacting the end-results of the company. During the program you will also join several lectures to learn about trading and our other departments to get a full understanding of our business.

Examples of potential projects that you could be working on:

  • The performance of our systems – profiling and optimizing our software and hardware
  • Developing tools in close collaboration with our traders to improve our trading strategies
  • Building a powerful tool to find errors in our systems by turning huge amounts of data into useful information

In all cases you can expect that all projects will be a valuable contribution to our business, focusing on actual issues that we face and like to see solved.
