Our exchange handles billions of ad requests every day, connecting thousands of publishers with demand partners across the global advertising ecosystem. The platform runs in the cloud across multiple regions and operates at a scale where performance, reliability, correctness, and every millisecond matter.\nYou will be part of a cross-functional platform engineering team focused on the Marketplace workflows that support how our core exchange operates. The components and tools help internal and external users manage marketplace settings, configure integrations for publishers and demand partners, review transaction setups, and ensure that platform behavior aligns with optimal liquidity and exchange performance.\nIn this senior SDET role, you will take strong ownership not only of test automation, but also of building new frameworks and maintaining existing ones - for TypeScript-based frontend applications as well as for API testing. This role is ideal for someone who wants to go beyond just testing and work on creating and maintaining test frameworks and testing approaches used across the organization.\nThe primary stack for this role includes: TypeScript, Playwright, React-based applications, Java, Python, Pytest, Spinnaker (CI/CD). The broader engineering environment also includes Node.js, GraphQL, GCP, and Kubernetes.\nYou do not need to be an expert in every part of our stack, but you definitely need to be eager to grow in those directions and bring a can-do attitude.\nPrior AdTech experience is helpful, but not required.\nWhat we offer:\nEmployment contract (22 595 - 25 254 PLN gross/monthly) OR B2B (181 - 202 PLN

across the organization, designing and maintaining tests across both layers for complex Marketplace workflows and integrations.\nImprove the reliability, speed, and maintainability of test automation frameworks and CI/CD pipelines.\nBe involved in all phases of platform development, from requirements and architecture design to validation, deployment, and release readiness.\nPartner with engineers and stakeholders across the organization to identify quality risks early, applying risk-based testing to make pragmatic coverage decisions across unit, integration, API, and end-to-end levels.\nInvestigate test failures, flaky tests, and production issues, driving root cause analysis with actionable improvements.\nCommunicate quality risks, trade-offs, and recommendations clearly to engineering, product, and business stakeholders.\nRequired qualifications\n5+ years of professional experience in test automation or software engineering in test, including hands-on experience designing and maintaining test automation frameworks, not just writing tests within them.\nStrong hands-on experience with TypeScript and Playwright (or a comparable frontend framework such as Cypress).\nSolid experience with API testing in Java and/or Python, ideally with pytest.\nPractical knowledge of test design techniques and risk-based testing.\nExperience with CI/CD tooling and pipelines, and improving automated test execution in CI environments.\nExperience with Google Cloud Platform, Kubernetes, Docker, Spinnaker, or similar cloud and deployment technologies.\nExcellent troubleshooting skills, able to triage complex issues across application, test, and infrastructure layers.\nExperience working in an agile engineering environment.\nStrong communication skills,
