You will join a strategic initiative within the Payments Processing domain, focused on improving the performance of the PIP payments processing pipeline ahead of the SEK Batch go-live. The project involves redesigning and optimizing several critical microservices to significantly increase processing speed and reduce latency.
The target is to achieve high-throughput, low-latency transaction processing at the level of 15–30k TPS, with scalability up to 50k TPS, while operating in a complex environment that combines event-driven microservices, data-intensive processing, and legacy systems. The solution must meet strict security, GDPR, and PCI compliance requirements typical for large-scale banking systems and international organizations.
