Opis stanowiska
Currently, for one of our Partners, we are looking for an experienced eDelivery Backend Test Automation Engineer (m/f/n) to support a project focused on backend and API test automation for eDelivery-related digital solutions.
Offer:
• Contract: B2B via SHIMI.
• Mostly remote, services must be performed from within the EU. Occasional travelling to Brussels may be required (the client may request on-site presence in Brussels with 7 days’, at contractor’s cost). For eDelivery profiles, 2 physical meetings with the customer are planned per 12-month period, max. 2 days each, at the contractor’s cost.
• Rate: 200–350 EUR/MD netto+VAT
Requirements
•
Java for writing robust, maintainable backend and API test automation code: at least 4 years.
•
API testing experience: at least 3 years.
• Experience with SoapUI for SOAP service testing or Postman for REST service testing: at least 2 years.
• Experience building and maintaining backend, non-UI-centric test automation solutions: at least 2 years.
• Experience with message format standards such as XML, XSD, XPath, WSDL, JSON, and JSON Schema: at least 2 years.
• Experience with defect tracking and test management tools, e.g. Jira, Zephyr: at least 2 years.
• Experience with version control systems, e.g. Git: at least 2 years.
• Experience designing, preparing, and monitoring automated tests for APIs, web services, and backend systems.
• Experience developing automated test suites for SOAP and REST web services using SoapUI, Groovy scripting, Postman, or Newman.
• Experience creating backend test automation architecture covering functional, integration, and contract testing layers.
• Experience validating message format correctness and protocol-level behaviour, including HTTP, TLS, and WS-Security.
• Experience integrating automated backend tests into CI/CD pipelines.
• Experience preparing structured and comprehensive test reports.
• Ability to read and interpret technical specifications, API contracts such as OpenAPI and WSDL, and message format standards.
• Excellent knowledge of English: minimum B2 level.
Nice to have
• Experience with eDelivery-related standards: OASIS ebMS3, AS4, SMP, BDXL, ebCore PartyId, and eDelivery profiles such as AS4, SMP, BDXL, and ebCore PartyId profile.
• Experience with Groovy as a scripting language within SoapUI and for lightweight automation tasks: assertions, property transfers, and data-driven tests.
• Experience integrating automated backend test suites into CI/CD pipelines such as Bamboo or GitLab CI.
• Experience with test data management for backend scenarios, including database seeding, mock services, and environment isolation.
• Experience with containerization technologies, e.g. Docker.
• Experience working in an international or intergovernmental organisation, European Institutions, or large public administration.
• Experience producing structured technical documentation in English.
• Good knowledge of French.
• For advanced profiles: over 15 years of professional experience.
• For senior profiles: over 20 years of professional experience.
Tasks
• Contribute to the development of one or more of the eDelivery products (Domibus, DomiSMP, DomiSML, eDelivery Conformance Testing Platform) in coordination with the eDelivery Solution and Technical Architect(s).
• Develop and maintain services and business logic using one or more backend programming languages.
• Maintain code integrity and organisation.
• Writing clean, functional, and maintainable code on the backend.
• Compile and analyse data, processes, and code to troubleshoot problems and identify areas for improvement.
• Perform unit/integration testing, debug, fix, and validate code changes.
• Deliver solutions that fulfil functional and non-functional requirements and align with user expectations.
• Design and implement distributed transaction patterns.
• Handle idempotency and duplicate detection across service boundaries.
• Implement reliable message delivery with at-least-once / exactly-once semantics.
• Manage eventual consistency and compensating transactions.
• Apply data and security best practices: input validation, authentication/authorization, secure storage, compliant logging and monitoring.
• Design and implement authentication and authorization flows to secure API endpoints and services.
• Implement certificate-based mutual TLS (mTLS) between services.
• Manage secrets, key rotation, and HSM integration.
• Conduct threat modelling and security review of API surfaces.
• Optimization of the application for maximum speed and scalability.
• Profile and optimize database query plans and index strategies.
• Design caching strategies.
• Identify and resolve contention points (connection pools, thread starvation, lock contention).
• Conduct load and stress testing, interpret results, and iterate.
• Design and develop versioned, backward-compatible REST or SOAP APIs.
• Define and enforce API contracts (OpenAPI, WSDL) across teams.
• Implement service discovery, load balancing, and circuit breakers.
• Govern inter-service communication patterns (sync vs. async, request-reply vs. event-driven).
• Design and operate message broker topologies (queues, topics, dead-letter handling).
• Implement and monitor async workflows with guaranteed delivery.
• Integrate with third-party systems via standard protocols (AS4, ebMS3, etc.)
• Handle schema evolution and backward compatibility in event-driven architectures.
• Implement structured logging, distributed tracing, and metrics collection.
• Participate in post-mortems and translate findings into architectural improvements.
• Design and implementation of data storage solutions.
• Choose appropriate storage engines for the access pattern.
• Design for data partitioning, sharding, and replication.
• Implement data migration strategies with zero or minimal downtime.
• Enforce data integrity constraints at the application and database level.
• Write technical documentation.
• Basic configuration of cloud services for back-end functionality.
• Write and maintain unit and integration tests to ensure code quality and reliability, integrating them into the CI/CD pipeline.
