Job Specifications
Location: Belgium
Service Delivery: Hybrid / 3 days On-site
Start Date: Nov/Dec
Duration: 3 Years
We are seeking a highly skilled Test Engineer with expertise in automation, integration, manual, and performance testing to ensure the quality, stability, and scalability of our enterprise-grade digital platform.
The platform is built on OpenShift and integrates key technologies such as HashiCorp Vault, MongoDB, PostgreSQL, MinIO, Elasticsearch, ELK Stack, NGINX, Squid, Solace, and Confluent Kafka.
You will play a vital role in designing and executing test strategies, developing automation frameworks, validating complex integrations, and conducting performance benchmarking of distributed systems.
Key Responsibilities
Test Planning and Design
Develop comprehensive test plans, cases, and strategies covering functional, integration, and performance testing.
Define test data requirements and acceptance criteria for platform components and services.
Collaborate with developers and DevOps teams to understand system architecture and integration points.
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 testing in OpenShift-based environments.
Manual and Exploratory Testing
Conduct manual functional testing of platform components to ensure accuracy and reliability.
Perform exploratory testing to identify edge cases and integration issues.
Validate configurations and system behaviour across multiple environments (dev, test, staging).
Integration Testing
Test end-to-end workflows across Vault, databases, message brokers, and microservices.
Validate data flow, API communication, and event streaming between Solace, Confluent Kafka, and downstream systems.
Verify integrations with NGINX, Squid, and ELK Stack for routing, caching, and observability.
Ensure proper Vault policy, secrets management, and access control behaviour.
Perform Factory Acceptance Testing (FAT) and System Acceptance Testing (SAT), generating reports for compliance submission.
Performance and Scalability Testing
Design and execute load, stress, endurance, and scalability tests using tools such as JMeter or Locust.
Analyze response times, throughput, and resource utilization of OpenShift-hosted services.
Identify performance bottlenecks and collaborate with engineering teams to optimize system performance.
Establish performance baselines and monitor improvements over time.
Defect Management and Reporting
Log, track, and verify defects through resolution using JIRA or Azure DevOps.
Participate in root cause analysis and provide detailed defect documentation.
Generate comprehensive test execution reports and quality dashboards.
Continuous Improvement
Contribute to automation coverage expansion and framework enhancement.
Recommend tools and best practices to improve testing efficiency.
Support CI/CD pipeline improvements for faster and more reliable deployments.
Required Skills & Experience
4–8 years of experience in software testing (automation, manual, performance, and integration).
Strong understanding of Kubernetes/OpenShift and containerized application testing.
Experience with API testing and automation using Postman, PyTest, Robot Framework, or RestAssured.
Hands-on experience with performance testing tools such as JMeter, Gatling, or Locust.
Proficiency in Python or Java for automation scripting.
Experience testing Vault, PostgreSQL, MongoDB, MinIO, Elasticsearch, and messaging systems (Solace, Kafka).
Familiarity with ELK Stack, Prometheus, or Grafana for log and metric validation.
Knowledge of Linux, Bash scripting, and networking fundamentals (NGINX, Squid).
Experience integrating tests into CI/CD pipelines (Jenkins).
Preferred Qualifications
Exposure to Infrastructure-as-Code tools (Terraform, Helm, Ansible).
Experience with security and compliance testing in cloud-native environments.
Understanding of service mesh, API gateways, and zero-trust architectures.
ISTQB or equivalent certification (advantageous).
Key Attributes
Strong analytical, problem-solving, and debugging skills.
Detail-oriented, self-driven, and accountable for quality outcomes.
Excellent collaboration and communication skills in agile, cross-functional teams.
Passionate about automation, performance, and reliability.
