SIG is a global quantitative trading firm founded with an entrepreneurial mindset and a rigorous analytical approach to decision making. As one of the largest proprietary trading firms in the world, we trade our own capital at our own risk. We are experts in trading all listed financial products and asset classes handling millions of transactions on exchanges around the world every day.

We are expanding our team in Sydney as we have a lot of exciting new projects and have a number of tech roles open (min 2 years of experience):

• Windows Powershell Engineer

• Software developers: C#, C++ or Python

• Quantitative Researcher

• Application Support Engineer

• Quantitative data developer: Python, linux

On a personal note, I worked in a few places in the region over past years and I think you will work in the best office in Sydney with 360 views of the Sydney Harbour Bridge, Sydney Opera House and the ocean. We have people returning back after trying their luck elsewhere as we offer good work/life balance. With free lunches, gym & health benefits, SIG is one of the best companies I worked for.
