Requirements

- Bachelor’s degree in computer science or a scientific discipline, or equivalent experience. - At least three years of professional C++ development focused on high-performance programs. - Experience writing unit and integration tests for C++ systems. - At least one year of professional experience developing Python programs or libraries. - Familiarity with accessibility and security compliance, and with version control such as Git or SVN. - Strong written and verbal communication skills and the ability to work effectively on a team.
