Role: Test Engineer – Platform (Automation, Integration & Performance)

Location: Brussels, Belgium (hybrid: 3 days onsite-2 days remote)

We’re looking for a Test Engineer with experience in automation, integration, and performance testing to join our dynamic platform engineering team. You’ll play a key role in ensuring quality, reliability, and scalability across a modern microservices-based ecosystem deployed on OpenShift.

Key Responsibilities

1. Test Planning & Design

• Develop detailed test plans, cases, and strategies covering functional, integration, and performance testing.
• Define test data and acceptance criteria for platform components and services.
• Collaborate closely with developers and DevOps teams to understand architecture and integration points.

2. Automation Testing

• Design, develop, and maintain automated test scripts for APIs, microservices, and UI components.
• Build reusable automation frameworks using Python, PyTest, Robot Framework, RestAssured, or similar tools.
• Integrate automated tests into CI/CD pipelines (Jenkins) for continuous testing.
• Implement automation for regression, smoke, and sanity tests in OpenShift environments.

3. Manual & Exploratory Testing

• Execute manual functional testing to validate deployments and configurations.
• Conduct exploratory testing to uncover edge cases and integration issues.
• Verify system behavior across dev, test, and staging environments.

4. Integration Testing

• Validate end-to-end workflows across Vault, databases, message brokers, and microservices.
• Test data flow and API communication between Solace, Confluent Kafka, and downstream systems.
• Verify integrations with Nginx, Squid, ELK Stack for routing, caching, and observability.
• Ensure proper Vault policy, secret management, and access control behavior.
• Lead Factory Acceptance Testing (FAT) and System Acceptance Testing (SAT), generating compliance reports.

5. Performance & Scalability Testing

• Design and execute load, stress, endurance, and scalability tests using tools like JMeter or Locust.
• Analyze response times, throughput, and resource utilization in OpenShift-hosted environments.
• Identify bottlenecks and collaborate with engineers to optimize performance.
• Define performance baselines and monitor improvements.

6. Defect Management & Reporting

• Log, track, and validate defects using JIRA or Azure DevOps.
• Perform root cause analysis and document findings.
• Generate detailed test execution reports and dashboards.

7. Continuous Improvement

• Enhance automation coverage and improve test frameworks.
• Recommend new tools and best practices to increase testing efficiency.
• Contribute to CI/CD optimization for faster and more reliable releases.

Requirements:

• 4+ years of experience in software testing (automation, manual, performance, integration).
• Solid understanding of Kubernetes/OpenShift and containerized application testing.
• Proficiency in Python or Java for automation scripting.
• Hands-on experience with Postman, PyTest, Robot Framework, RestAssured.
• Strong knowledge of JMeter, Gatling, or Locust for performance testing.
• Experience testing Vault, databases (PostgreSQL, MongoDB, MinIO, Elasticsearch), and messaging systems (Solace, Kafka).
• Familiarity with ELK Stack, Prometheus, Grafana for logs and metrics.
• Working knowledge of Linux, Bash scripting, and networking (Nginx, Squid).
• Experience integrating tests into Jenkins CI/CD pipelines.
• EU CITIZENSHIP
