LMAX is looking for a C++ and Python developer to join our middle-office team. This team works closely with the infrastructure, research and treasury teams. In this position you can expect to take a significant role in the development of our trade reconciliation, back-testing framework and trading monitoring. You will be working with the team to design and implement our trading system with a predominant focus on data engineering. We are looking for developers who are confident in their ability to develop software, both with others and on their own. A finance or trading background is not required.
Our code base is currently split between C++, a language which the infrastructure team works on, and Python, which is used by the research team for analysis and automation. This role is part of a new team to help bridge the gap between the two.
Working on financial data brings some interesting technical challenges in the area of throughput. Here you can expect to focus more directly on software performance than at other organisations, while still striving for easily maintainable code. You will be digging deep into our system, understanding how it works and where it can be improved.
We rely heavily on validating our system using our extensive test suites. We test at all levels of our system from unit testing to full end-to-end tests in which the entire system is launched and tested in a simulated environment. All tests are run every 15 minutes on our CI to give us a fast and reliable feedback cycle. There is no waiting for overnight test suites here. You can also expect to develop performance benchmark tests to monitor how our software's performance is improving over time.
Responsibilities
- Produce clear, well-structured and fully tested C++ and Python code
- A focus on writing high throughput software
- Use pair programming to increase the spread of knowledge and avoid siloing
