• Work with logs, transaction data, and system behavior to identify root causes and propose effective solutions
• Configure client-specific payment setups, including routing rules, cascades, payment methods, and operational logic
• Optimize client performance by improving configurations and reducing reliance on engineering escalations
• Collaborate with developers and QA teams to resolve complex technical incidents and integration challenges

• Basic knowledge of APIs, including request/response structures, HTTP status codes, and webhooks
• Ability to read and apply API documentation in real-world integration scenarios
• Experience working with logs and debugging technical issues independently
• Strong problem-solving skills with the ability to handle multiple integrations and maintain context
• Ability to work autonomously without heavy reliance on developers for first-level troubleshooting
• Intermediate English level or higher for communication with international partners
• Nice to have: experience with payment gateways, routing logic, Postman/Swagger, monitoring tools (e.g., Sentry, Grafana), or backend system understanding

Benefits:

• Flexible work setup with remote or office-based options
