LMAX Group is looking for a tester for our C++ development team. In this position you can expect to help design and implement automated testing suites as well as conduct exploratory testing of our trading applications. You will also be assisting the development team to ensure that new code is designed with testing in mind. We are looking for testers who are confident in their ability to create tests, both with others and on their own.
A finance or trading background is not required.
What you will be working on
Our code base currently has extensive automated tests from unit test to integration tests and acceptance tests. All our tests run through our CI every 15 minutes and we are looking to maintain and expand this test suite as we create new features. There will also be some time allocated to exploratory testing to try and find elements of the system that are not functioning correctly. Our developers prefer to practice TDD. This is the first Tester hire for the team, so you will be expected to drive the testing strategy to prove functional correctness. Exploratory testing to identify obscure edge cases and complex interactions, both on your own and pairing with developers, is expected to be a significant part of this role.
