• Design, build, and maintain automated testing frameworks • Develop and execute unit, integration, regression, and end-to-end automated test suites • Create and maintain automated tests for complex workflows • Integrate and manage automated testing within CI/CD pipelines • Conduct performance, scalability, and load testing • Identify, document, and track bugs and system weaknesses

• Design, build, and maintain automated testing frameworks across web applications, APIs, backend services, and integrations. • Develop and execute unit, integration, regression, and end-to-end automated test suites to ensure system reliability and stability. • Create and maintain automated tests for complex workflows, edge cases, and data/state transitions across services. • Integrate and manage automated testing within CI/CD pipelines using tools such as GitHub Actions, GitLab CI, or Jenkins. • Conduct performance, scalability, and load testing across core services and infrastructure. • Identify, document, and track bugs and system weaknesses, partnering with engineering teams to improve QA processes, automation coverage, and testing standards.

• Design, develop, and maintain automated test suites using C#, .NET. • Build automation for API, integration, end‑to‑end, performance, and regression testing. • Implement testing best practices, including shift‑left testing and quality‑driven development. • Ensure high coverage and reliability of automated tests across services and microservices. • Build and execute cloud‑based test strategies across AWS services (Lambda, API Gateway, S3, SNS/SQS, DynamoDB, ECS/EKS, IAM). • Validate architecture resilience, scalability, and security through automated and exploratory testing. • Use **infrastructure‑as‑code** tools (CloudFormation / Terraform / CDK) to provision test environments. • Develop and optimise CI/CD pipelines using GitHub Actions / Azure DevOps / Jenkins / GitLab CI. • Integrate automated tests into pipelines to ensure rapid, reliable delivery. • Embed quality gates, security scans, and performance checks into end‑to‑end pipelines. • Collaborate with DevOps/Platform teams to build repeatable, self‑service test environments. • Work closely with developers, product managers, and SRE teams to drive a quality‑first culture. • Participate in code reviews, architecture discussions, and design sessions to influence quality early. • Troubleshoot defects, conduct root cause analysis, and implement preventative fixes.

• Design, develop, and maintain automated tests (UI, E2E, functional, and integration) across multiple platforms and environments: Linux, Windows, macOS, Docker, and WSL. • Expand test coverage for new and existing functionality. • Monitor automated test execution results. • Debug and troubleshoot test failures, distinguishing product issues (regressions) from infrastructure-related issues (including test, framework, or environment). • Optimize test execution time and reliability. • Improve test automation stability and contribute to automation frameworks. • Report bugs in YouTrack and verify that they are properly fixed and backported. • Participate in release quality assessments. • Collaborate with QA and developers on testability and quality improvements. • Help define test strategies and quality gates for your team. • Support manual QA activities when needed. • Define and track quality metrics, including testing coverage, failure rate, and flakiness. • Identify gaps in test coverage and propose solutions. • Improve domain-specific test infrastructure and CI/CD pipelines within your team's scope. • Share knowledge about automation best practices with other team members. • Work with the tooling team to adopt new frameworks and practices.
