Zusammenfassung

EPC Network is seeking a QA Engineer focused on automation to ensure our SaaS platforms scale with high reliability.

You’ll build test suites in QASE, integrate tests into CI/CD, and collaborate with AI/ML and DevOps teams to improve coverage and performance across distributed systems.

You’ll work with modern tech stack (React/Next.js, Node.js, Kubernetes) and help drive observability, resilience testing, and contract testing to support tens of millions of events daily.

Qualifikationen

• 3+ years of experience in software testing (automation-focused).
• Hands-on experience with Playwright for end-to-end and API testing.
• Experience with CI/CD pipelines and integrating automated tests into build workflows.
• Knowledge of testing strategies for event-driven and distributed architectures.

Aufgaben

• Build and optimize test cases in QASE, ensuring full coverage across complex event-driven systems.
• Collaborate 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).
• Drive observability in testing by integrating with monitoring tools (Grafana, Prometheus, Datadog).
• Participate in chaos and resilience testing to validate distributed systems under stress.
• Actively shape QA strategy and tooling for our next-generation SaaS and automation platforms.

Jobbeschreibung

At EPC Network, we’re not just a digital marketing company; we’re a platform for career transformation and personal growth. Our people-first approach shapes our corporate culture, fostering a team of passionate, smart, and energetic individuals who strive to grow professionally in an international, fast-paced environment.

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.

Your Role

Currently 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

• 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).
• 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).
• Excellent teamwork, communication, and problem-solving skills.
