QA Engineer Playwright Automation SaaS Platforms

Hi there,

At Web Impact , we’re more than just an email marketing agency and digital solutions provider. We’re building cutting-edge, socially impactful products that redefine how businesses operate in the digital world.

Our team of experienced marketers, designers, and developers delivers measurable, business-driving results for our clients, but that’s just the beginning. Behind the scenes, we are actively developing next-generation automation platforms and SaaS products capable of processing tens of millions of real-time events every day .

Our technology stack is modern, scalable, and future-proof : React.js, Next.js, Node.js, Elixir, Golang, Kubernetes, CI / CD pipelines, PostgreSQL, BigQuery, Clickhouse, AWS, Redis, RabbitMQ, Kafka, and our proprietary, self-hosted GenAI technology.

We tackle highly complex engineering challenges - from external system integrations with strict rate limits to massive asynchronous event pipelines , all in mission-critical environments where performance, scalability, and reliability are paramount. That’s why we’re looking for a QA Engineer who thrives in automation, loves solving “impossible” problems, and ensures that products scale with uncompromising reliability.

What You’ll Do

Design, develop, and maintain automated test suites using JavaScript / TypeScript and Playwright (UI, API, and end-to-end).

Build and optimize test cases in QASE , ensuring full coverage across complex event-driven systems.

Collaborate closely with developers, DevOps, and AI / ML teams to integrate shift-left testing into CI / CD pipelines.

Implement contract testing for microservices and integrations with external APIs (handling strict rate limits and async flows).

Contribute to performance, load, and reliability testing (JMeter, k6, or similar), ensuring systems handle tens of millions of daily events.

Drive observability in testing - integrate with monitoring tools (Grafana, Prometheus, Datadog) to track quality metrics in production.

Participate in chaos and resilience testing to validate distributed systems under stress and failure conditions.

Actively shape QA strategy and tooling for our next-generation SaaS and automation platforms.

What We’re Looking For

3+ years of experience in software testing (automation-focused).

JavaScript / TypeScript - designing and implementing automation frameworks

Experience in Playwright for end-to-end and API testing.

Hands-on experience with QASE or similar test management tools.

Solid knowledge of testing strategies for event-driven and distributed architectures .

Familiarity with API testing (REST, gRPC, WebSockets).

Experience with CI / CD pipelines and integrating automated tests into build workflows.

Knowledge of PostgreSQL and the ability to work with large datasets for validation.

Experience with performance / load testing tools (JMeter, k6, Locust).

Experience with SmartLook or a similar tool is a plus.

Bonus points for : contract testing (e.g., Pact), chaos testing, or experience testing AI / ML pipelines.

Excellent teamwork, communication, and problem-solving skills.

Fluent in English and Polish .
