Write clean, tested, and well-documented code that follows best practices in performance, security, and scalability.
Identify and troubleshoot performance bottlenecks to ensure high availability and reliability of services.
Keep up to date with the latest fintech and Golang trends, integrating relevant advancements into our ecosystem.

Requirements

Solid understanding of backend architectures, including microservices, RESTful APIs, or gRPC-based services.
Familiarity with payment systems, card processing, or banking integrations (SEPA, SWIFT) is highly advantageous.
