About the role :Are you a seasoned C++ craftsman who gets genuinely excited when someone mentions stuff like “Btrieve” in 2025?We're inviting you to strengthen our eBlox payroll team - the powerhouse behind Belgium's most popular payroll solution for mid-to-large organizations. 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! 😉You'll join an international, agile squad of 16 talented engineers (developers, functional analysts, testers, scrum master, and product owner). This self-organizing team offers growth opportunities beyond your core responsibilities - take ownership of areas that match your interests and aspirations.What You'll Actually Be Doing
  • Enhance, maintain and refactor our legendary C++ system - Work with a mature, battle-tested codebase that's been processing millions of payslips reliably for years
  • Master the ancient arts of specialized technologies - You'll work with our optimized Btrieve databases and proven MFC interfaces that deliver rock-solid performance for high-volume payroll processing
  • Contribute across the full product lifecycle - From brilliant ideas to production deployment and ongoing optimizations
  • Bridge the business-tech gap - Work with our business experts to translate complex Belgian payroll requirements into elegant technical solutions
  • Debug like a detective - Troubleshoot issues that span decades of development decisions (no direct customer contact required)
While guaranteeing that those 500,000+ Belgian workers get their payslips correctly and on time every month, we're steadily modernizing our solution. We've already virtualized the GUI layer, giving users sleek web interfaces while our performance-optimized backend continues delivering rock-solid reliability. Now we're actively refactoring the backend - this is where you come in to help us modernize the core while preserving everything that makes it so dependable.Your Profile and SkillsEssential Experience:
  • 5+ years of C++ development in complex software environments
  • Boost and MFC knowledge - Because not everything can be solved with modern frameworks
  • Database experience - Especially Btrieve (yes, really!) and MS SQL
  • Windows profiling tools like VTune - performance matters when processing half a million payslips
  • Degree in IT or equivalent battle scars from the software trenches
Bonus Points:
  • If you've survived legacy modernization projects
  • TDD experience
  • CI/CD systems - Azure DevOps, Jenkins, or similar
  • Visual Studio mastery - Our primary IDE
  • Python scripting - Automation is your friend
  • Payroll domain knowledge - Understanding why Belgian tax calculations are... Special
What We're Looking For:We want someone with a "Can Do!" attitude who can:
  • Self-educate and adapt - Our codebase will teach you things they don't cover in university
  • Work autonomously - You'll own your problems and solutions
  • Collaborate internationally - Our team spans Belgium (Antwerp) and Poland (Katowice)
  • Communicate clearly - English is our lingua franca, and you'll be explaining complex technical decisions
  • Embrace the agile mindset - Continuous learning, transparent feedback, and value delivery
Why You'll Love Working Here
  • Actually important work - Your code ensures +500.000 real people get their paychecks, holiday pay, and 13th month bonuses without Belgian tax authorities getting cranky
  • Vintage problems, modern tools - We use contemporary development practices on fascinatingly complex legacy systems
  • Hybrid Setup: Work flexibly from home, with at least 1 monthly visit to our Katowice office and occasional extended office periods. Because sometimes you need to be in the same room to figure out why that 20-year-old calculation module does what it does.
