Manual QA (Backend)

In this role, you will

- Perform manual testing of backend REST APIs and WebSocket flows using Postman, Swagger, and curl

- Validate data and prepare test states in MongoDB

- Create and maintain test documentation, including test cases in Qase, checklists, and bug reports in Jira

- Review product requirements and technical designs before implementation

- Test A/B experiments, monetization flows, and analytics events, and work with internal tools such as admin panels, brand settings, and feature flags

- Investigate bugs using logs and metrics in Grafana, identify root causes, and distinguish between client-side and backend issues while contributing to improved testing efficiency and quality

It’s all about you

- Have 2+ years of experience in manual backend testing using API tools such as Postman, Swagger, or curl

- Have hands-on experience with MongoDB, including writing queries with filters and projections and using aggregation pipelines; confident SQL skills are an alternative, while MongoDB experience is preferred

Would be a plus

- Familiarity with Grafana, Loki, or Kibana for log and metrics analysis

- Basic API test automation skills using JavaScript/TypeScript or Postman tests
