Job description

Your job

This role is crucial for our organization. Our Technology team is small and therefore you get a lot of responsibilities and freedom! You are triggered by being faster than the competitors and you like to focus on quality. As you can imagine in a small team, there is a flat hierarchy and everybody is really hands-on to be the best in what we do!

We are looking for senior C/C++ Engineers with extensive knowledge and experience in building, testing, monitoring and maintaining large scale parallel applications and databases. As a C/C++ Engineer at Mathrix in the low latency environment, your focus will be on the code which facilitates the automated trades on various exchanges worldwide.

Our companies’ performance is highly dependent on the performance of our data processing pipelines. You will regularly need to appeal to all aspects of your developers’ skillset to find new and innovative ways to optimize your code. Some examples:

low-latency networking code for fast communication with exchanges

context-switch-free code

design and implement custom data storage structures with minimalistic footprint

data pipelines using a streaming paradigm

complex trading logic for the decision engine with the lowest possible compute time

re-implement existing code using advanced features of the CPU (SIMD)

To accommodate the growth of the company, we spend increasing efforts on the maintainability and manageability of our large, highly optimized and multithreaded codebases while preserving its main purpose (low latency). You will have to maneuver yourself between these worlds to get the best results.

In addition to writing code, the Technology team builds and maintains the global (hardware) infrastructure to facilitate the trading.
