Contribute to release quality gates, regression testing strategies, smoke tests, and pre-release validation within CI/CD pipelines.
Identify risks across distributed payment systems and proactively strengthen testing coverage, reliability, and engineering quality standards.
Explore AI-assisted QA and automation techniques where they can improve testing efficiency and effectiveness.
Proven experience in QA engineering, test automation, or a closely related software quality role, with strong ownership of complex systems.
Hands-on experience testing REST APIs, including JSON, request/response validation, and API-driven workflows.
Strong understanding of backend systems, distributed services, and software integration patterns.
Practical experience with test automation frameworks such as Playwright, RestAssured, or similar tools.
Ability to diagnose technical issues using application logs, databases, API traces, and other debugging tools.
Experience working with CI/CD pipelines and integrating automated quality checks into software delivery processes.
Strong analytical and problem-solving skills, with the ability to identify risks beyond individual feature requirements.
SQL and data-validation skills are an advantage.
Familiarity with prompt engineering or AI-powered tools for QA and test automation is beneficial.
Strong communication and collaboration skills, with the ability to work effectively with engineering and product stakeholders.
A proactive mindset and willingness to take ownership of quality improvements across the wider engineering lifecycle.
Fully remote-friendly working environment, with flexibility around working hours.
Modern technology stack and engineering-focused environment.
Exposure to scalable distributed systems, external financial integrations, and cloud infrastructure.
