Senior Backend Developer (File Processing)

The role is about:
We are a lean but growing engineering team working in the eCommerce payment processing space. As we expand, we are looking for a Senior Backend Developer to join our File Processing squad and take ownership of our pipeline migration. You will lead the transition from legacy Perl/crontab infrastructure to a modern, observable, and maintainable Python-based architecture.

You will play a central role in designing, building, and operating the systems that process daily scheme files (e.g., Visa and Mastercard clearing/settlement files), replacing manual production access patterns with robust orchestration and deployment automation. In this small team, your voice carries real weight—you will help define how we build, not just what we build.
