What makes the role special

Group-IB Fraud Protection is an advanced solution designed to counteract the most sophisticated fraud schemes against an organization, regardless of the industry. Group-IB Fraud Protection helps you detect fraud schemes such as social engineering attacks (phishing sites, email scams, etc.), user account fraud, payment fraud, malicious bot activity, web injections, mobile trojans, malware-related and credit frauds, and more.

Tasks to solve

• Design, write, and maintain test cases, checklists, and test configurations based on requirements and technical documentation.
• Perform manual functional, regression, and integration testing of backend services.
• Identify, reproduce, localize, and verify defects; work closely with developers to drive them to resolution.
• Generate detailed test reports: test execution results, defect summaries, coverage metrics, and key observations.
• Analyze logs and event data using ELK stack to support root-cause investigations.
• Develop and maintain test documentation — test plans, test suites, traceability matrices.
• Understand the system end-to-end and proactively suggest improvements that make it more stable, predictable, and observable.

This role is perfect for you if

• You have solid hands-on experience in manual QA, with a strong focus on backend and API testing (REST, message queues, server integrations, mock testing).
• You're comfortable working with various databases — relational, NoSQL, columnar — writing queries to validate data integrity.
• You have experience testing high-load, distributed systems and know what to look for when things go wrong at scale.
• You have strong analytical skills and genuinely enjoy digging into complex systems to figure out what's happening.
• You write clear, structured bug reports and test documentation that others can actually use.
• Experience building or contributing to automation frameworks (Python/Pytest, Go, or JavaScript) is a significant plus — we're heading in that direction and would love your help.

What else we appreciate in our team

• Collaborative spirit — you make the team around you better.
• Technical curiosity and a drive for continuous improvement.
• Enthusiasm for learning new tools and owning quality end-to-end.
• Python skills are a nice bonus; Go experience is also welcomed.
