QA Tech Lead

Poland

Location: Poland

We Are: 

RTB House is a next-generation performance demand-side platform (DSP) that uses proprietary Deep Learning AI algorithms to help brands grow. The company is the market leader in driving performance using Deep Learning across the entire purchase funnel. 

Founded in 2012, and now operating in 90+ markets, RTB House has always been private-by-design. It embraces first-party advertising and a relentless approach to innovation. RTB House offers end-to-end Deep Learning-powered AdTech products and solutions to maximize conversion, drive new customer acquisition, create engagement, and fuel long-term demand for a global base of clients. 

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. 

You Will:

  • 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:

Must have

  • 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.
  • Experience using AI to work smarter .
  • 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?"

Selected Technologies: 

  • Python
  • Cypress
  • FastAPI/Django
  • TypeScript
  • Kubernetes
  • Google Cloud Platform
  • PostgreSQL
  • AlloyDB
  • BigQuery

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 work 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, not a code factory
