We are looking for a Senior QA Automation Engineer to ensure the quality of an enterprise AI solution built around MCP (Model Context Protocol) Servers. This role is well suited for a technically curious professional who enjoys working at the intersection of quality engineering and emerging AI architectures. You will play a critical part in validating the reliability and correctness of complex, agent-driven systems. This is a great opportunity to shape testing practices for a cutting-edge AI platform from the ground up.
Responsibilities
- Analyze product and architecture requirements to define the QA strategy and determine test coverage for MCP-based AI solutions
- Design and implement Python-based automated tests for MCP Servers, tools, resources, APIs, and integrations
- Validate MCP protocol behavior, including tool discovery and execution, schemas, error handling, authentication/authorization, and integration scenarios
- Test agent-to-MCP-to-tool workflows, covering positive, negative, edge, failure, and security scenarios
- Validate the reliability, performance, scalability, and production readiness of MCP services
- Define quality gates and integrate automated testing into CI/CD pipelines
- Identify quality risks, investigate test failures, and collaborate closely with developers and architects to drive improvements
Requirements
- A minimum of 3 years of relevant experience with the ability to independently own test strategy and quality
- Deep, hands-on knowledge of MCP Server/Model Context Protocol and its underlying architecture
- Strong Python automation skills, including experience with API and integration testing
- Experience testing distributed backend systems, APIs, microservices, and integrations
- Good understanding of GenAI/LLM and agentic architectures, including agents, tools, prompts, and MCP-based integrations
- Experience with CI/CD and modern automated testing practices
- Strong analytical skills with the ability to translate requirements and architecture into comprehensive test scenarios
- Excellent English communication skills (B2 level or higher)
Nice to have
- Familiarity with GitHub for version control, collaboration, and managing test automation code
- Experience with Kubernetes for testing and validating containerized applications and services
