Senior Test Automation Engineer

We are looking for an experienced QA Automation Engineer to take ownership of test strategy and automation for a modern cloud-based web platform. In this role, you will design and maintain automated API and UI tests, ensure software quality through CI/CD processes, and leverage AI-powered tools to improve testing efficiency and reliability.

• 5+ years in software quality engineering
• Proven experience in defining test strategies for web platforms or SaaS products
• Proven experience in setting up, owning, and maintaining test automation repositories using Python or TypeScript, including repository structure, coding standards, CI integration, code reviews, and long-term maintenance
• Strong hands-on experience automating REST API tests (e.g., pytest + httpx, Playwright API testing), including: schema validation against OpenAPI (contract testing is a plus) asynchronous flows (polling, state machines, queues, WebSockets) auth and access control (OAuth2/OIDC, JWT, role- and tenant-based access, negative cases)

• Experience building quality gates in GitLab CI (or a similar tool) with Docker. Experience testing cloud-hosted applications and debugging through logs, metrics and traces
• You understand how LLM-based agents behave (tools, memory, non-determinism). You use AI assistants (e.g., Claude Code, GitHub Copilot) every day in your own work: writing tests, analysing failures and documenting. You review AI-generated code critically
• Strong collaboration and reporting skills; ability to work in cross-functional and international teams. Strong analytical and problem-solving skills with attention to detail

Nice to have:

• AWS experience (Lambda, API Gateway, DynamoDB, S3, CloudWatch, Bedrock AgentCore).
• Experience with Strands or other agent frameworks (e.g., LangGraph, CrewAI).
• Familiarity with LLM evaluation tools (e.g., DeepEval, Promptfoo, Ragas).
• Experience with MCP / A2A servers and protocols.
• Knowledge of vector-based retrieval systems.
• Experience in monitoring & observability.
• Experience with full-stack application testing.
• Security testing: working knowledge of the OWASP Top 10 (web and API) and hands-on penetration testing experience (e.g., Burp Suite, OWASP ZAP)
• Knowledge of GxP or regulated environments is a plus.
• Strong analytical mindset and attention to detail.

• Participation in interesting and demanding projects
• Flexible working hours
• A great, non-corporate atmosphere
• Stable employment conditions (contract of employment or B2B contract)
• Opportunities for development and promotion
• Attractive package of benefits
