Senior QA Automation Engineer – Integration Testing

About the role

Avenga, an international engineering firm with 6,000+ experts worldwide, is looking for an experienced Senior QA Automation Engineer to build automated integration testing for a new Apache Camel platform and support the TIBCO-to-Camel migration. The focus is on creating reusable tools and procedures for long-term integration and regression testing, not just a one-off migration. The role involves technical integration testing, test automation and close collaboration with developers, architects and testers.

Key responsibilities

• Design and execute integration tests covering APIs, message contracts, transformations, routing, error handling and end-to-end flows.
• Develop reusable Java test automation components for multiple integration services.
• Build automated tests for TIBCO-to-Apache Camel migration releases and establish a sustainable regression test suite.
• Implement comparative testing to verify behavioural consistency between legacy TIBCO and new Camel implementations.
• Automate synchronous and asynchronous integration scenarios involving Kafka and JMS.
• Analyze logs and trace transactions using Kibana/Elasticsearch and correlation IDs; validate data consistency using SQL (Oracle/PostgreSQL).
• Create mocks, stubs and test data to simulate upstream and downstream systems.
• Integrate automated tests into CI/CD pipelines and define testing standards and best practices for Camel integration services.
• Collaborate with developers to identify test scenarios and improve service testability, and document solutions and knowledge transfer.

Required profile

• Minimum 5 years of experience in backend/integration testing or system integration.
• Strong knowledge of API and integration testing, including REST, SOAP, synchronous/asynchronous communication, error handling, retries, timeouts and complex integration flows.
• Hands-on experience with Java test automation, preferably with RestAssured, Serenity BDD or similar frameworks.
• Good understanding of JSON, XML, schemas and API contracts; knowledge of SQL and ability to validate data at database level.
• Ability to independently analyze integration services, design test coverage and troubleshoot issues across distributed systems.
• Slovak or Czech native speaker with English at B1 level or higher.

Required skills

• Git, CI/CD, Jenkins and logging/monitoring tools such as Kibana or Elasticsearch.
• Familiarity with Swagger/OpenAPI, JIRA, TestRail or equivalent tools.
• Nice to have: Apache Camel, TIBCO BusinessWorks, TIBCO EMS, Kafka, JMS, Enterprise Integration Patterns, Docker, Kubernetes, service virtualization, JMeter/LoadRunner, BPMN and Camunda, and experience in telecommunications (BSS/OSS) or integration platform migration.

What we offer

• Guaranteed minimum salary of EUR 2,700 gross per month, negotiable depending on profile.
• Language courses, MultiSport card, sick days, meal allowance and company events.
• Hybrid remote work after mutual agreement.
• Internal and external training courses and high-quality hardware and software.
