Are you a C++ developer who gets genuinely excited when someone mentions stuff like “Btrieve” in 2025?

Then we’re inviting you to strengthen our eBlox payroll team - the powerhouse behind Belgium’s most popular payroll solution for mid-to-large organizations.

eBlox is a user-facing application, used by payroll professionals to manage their payroll processes.

We process over 500,000 payslips monthly, which means your code directly impacts half a million Belgian workers getting paid correctly and on time. No pressure!
