Job Description

Our Product Tools team is responsible for developing and maintaining self-service platforms for managing advertising campaigns with advanced reporting and forecasting capabilities — used by both internal and external users. As a QA Tech Lead, you will play a pivotal role in designing the quality strategy and technical foundations of our testing ecosystem. If you enjoy building frameworks and setting technical standards across the full quality spectrum, this role is for you.

Job Responsibility

  • Architect and oversee the overall testing strategy for both frontend and backend systems
  • Design, develop, and scale automated testing frameworks using Python or TypeScript (e.g., Pytest, Playwright, Cypress)
  • Drive the technical evolution of our QA processes, ensuring they are integrated into the CI/CD pipeline and cloud infrastructure
  • Perform high-level exploratory testing of complex new features, providing feedback on system design and edge cases
  • Collaborate as a technical peer with developers, architects, and product stakeholders to ensure quality is built-in from the design phase
  • Mentor the team in best practices for testability, automation patterns, and defect management

Requirements

  • At least 5 years of experience in QA roles, with a proven track record of designing automation architectures
  • Experience in at least 2 different companies/organizations, demonstrating exposure to diverse technical environments and challenges
  • Strong proficiency in either Python or TypeScript for test automation
  • Deep understanding of modern software architecture, API testing, and frontend automation patterns
  • Use AI tools (LLMs, agents, coding assistants) to speed up writing test scripts, generating edge-case data, and documenting created artefacts
  • Experience in owning or organizing QA processes at a team or department level
  • A "Lead" mindset: willingness to balance high-level strategy with hands-on automation and exploratory testing
  • Technical fluency: Git, Linux basics, and solid SQL skills
  • Languages: English (B2+), Polish (B2+)

Nice to have

  • Experience in building/scaling QA chapters in fast-growing engineering teams
  • Deep knowledge of CI/CD pipelines and cloud-native environments (GCP, Docker, Kubernetes)
  • Performance and load testing expertise
  • Experience with GraphQL and BigQuery
  • UX-oriented mindset — advocating for the end-user by asking "is this what customers will love?" rather than just "does it meet the spec?"

What we offer

  • 100% remote — collaboration from anywhere in Poland or from our offices in Warsaw or Kraków
  • Flexible collaboration model — we trust you to manage your time
  • Shape the QA process — with a small QA team, you'll have a direct impact on how testing is done
  • Influence the product — we cooperate closely with users, developers, and UX designers
  • your voice matters in the final shape of what we ship
  • Freedom in tooling — we're open to adopting better tools and technologies when there's a good case for it
  • Stable tech company — RTB House is an AI/ML-driven product company with a long-term perspective
