A day in the life:

08:00 - 08:15 AM:        

I arrive at the office and walk into the lounge to get myself a sandwich and a glass of orange juice and while I am at it, I bring some coffee for my teammates. I log in to my computer and walk towards the huddle area to listen to the daily morning meeting which gets us up to speed on what has happened over night and the most important things to expect for today.

08:30 - 10:00 AM:        

After the morning meeting I start running the quantitative models that are already in production and send updated parameters to Traders so they can put it in their trading engine.

10:00 - 12:00 AM:        

Mostly programming, I start working on my to-do list which are mostly researching and designing new trading algorithms, but projects can range from statistically investigating a trading idea in Python, R or MATLAB to coding new improved versions of trading algos in JAVA. As an example today I was working on a bug in one of the trading algorithms that I wrote as we noticed it doing some weird trades.

12:00 - 12:30 PM:        

Lunchtime! At Flow we enjoy a great lunches. To illustrate this: Every now and then, we get spareribs and nothing makes me happier.

12:30 - 17:45 PM:        

After lunch I continue where I left off and try to finish any projects with pressing deadlines, or ad-hoc research requests that come in.

17:45 PM:                   

As most European exchanges close, I shut down my PC and head home. However, on Fridays it usually worthwhile to stay and have a drink at our in-house bar where some good old trash talking usually leads to a counterstrike team battle at our gaming room combined with a few beers.

What You Need to Succeed:

  • An academic degree (e.g. Physics, Math, Econometrics, Computer Science, Engineering, Machine Learning or similar);
  • Experience with a scientific programming language ( e.g. Python / MATLAB / R or similar);
  • Experience with JAVA and/or C ++ (or similar) is an advantage;
