Job description

Overview

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

• Strong expertise 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.

Our Tech Stack

• Test Automation: JS/TS + Playwright, Jest, Pact, k6

• Test Management: QASE

• Backend: Node.js, NestJS, Golang, Elixir

• Messaging & Queues: RabbitMQ, Redis Streams, Kafka

• Data: PostgreSQL, BigQuery, Clickhouse

• Infrastructure: AWS, Fly.io, Digital Ocean, GitLab

• Front-end: React.js, Next.js

• AI/ML: Proprietary self-hosted GenAI models, integrated ML pipelines

Why Join Us?

• Work on "cosmic" scale projects - platforms that process tens of millions of events daily, with complexity few companies can match.

• Ownership from day one - shape QA strategy, tooling, and processes.

• Collaborate with top talent - experienced engineers, marketers, and AI specialists who thrive on big challenges.

• Innovation-focused environment - we explore cutting-edge tech, not just "play it safe".

• Social impact - contribute to products that make a real difference in businesses and communities.

• Competitive compensation and growth opportunities.
