Join one of Europe’s leading payment technology providers as they continue to expand their high-performance transaction processing platform. You’ll work in a product-focused environment where stability, speed, and scalability are the top priorities – supporting real-time payments, digital wallets, and transaction processing used across multiple countries.

Your mission:

• Develop, maintain, and improve high-performance C++ code

• Write functional tests and help improve regression frameworks
• Translate business requirements into scalable technical solutions

Your background:

• Strong knowledge of C, C++, STL, Boost
• Familiar with socket programming and multithreading (race conditions, deadlocks, etc.)
• Experience working with MySQL, MariaDB, or Oracle
• Solid understanding of data structures and systems design
• Bonus points for knowledge of ISO 8583, ISO 20022, digital wallets, and real-time payments
• Fluent English – German is a plus, but not required
• Hybrid working – up to 50% remote possible
• Long-term stability in a profitable, fast-growing tech company
• Full development lifecycle ownership – design to deployment
• Regular performance reviews, training budget, and access to an e-learning platform
• EGYM Wellpass membership (gym, pools, yoga, bouldering, and more)
• Monthly €50 shopping voucher + discounts on various brands
• Regular team events: summer party, Oktoberfest, Christmas, and more
