QA/Integration Test Engineer

Required Qualifications

Testing & Automation

• Integration and contract testing for event-driven, distributed systems.
• Automated test frameworks: xUnit/NUnit, and an API testing tool (Postman or equivalent).
• Kafka producer/consumer test harness development.

Event Streaming & Schema Management

• Schema compatibility testing against a schema registry, as part of a CI gate.

Test Environments & Data

• Docker Compose-based test environment ownership.
• Test data management across multiple, heterogeneous data stores.

Resilience & CI/CD

• Failure-mode and resilience testing (idempotency, retries, conflict resolution).
• CI/CD pipeline integration for test gating.

Projects

Role OverviewWe are seeking a Senior QA Automation Engineer to own quality for event-driven, distributed systems. In this role you will design and maintain integration and contract testing, build Kafka-based test harnesses, enforce schema compatibility as a CI gate, and drive failure-mode and resilience testing across a heterogeneous data landscape. You will be responsible for embedding automated test gating directly into the CI/CD pipeline so that quality is validated continuously and early.

Key Responsibilities

• Design and maintain integration and contract testing for event-driven, distributed systems.
• Build and enforce schema compatibility testing against a schema registry as part of a CI gate.
• Develop and maintain Kafka producer/consumer test harnesses.
• Own and evolve Docker Compose-based test environments.
• Build and maintain automated test frameworks and API test suites.
• Manage test data across multiple, heterogeneous data stores.
• Design and execute failure-mode and resilience testing, including idempotency, retries, and conflict resolution.
• Integrate automated tests into CI/CD pipelines for test gating.

Nice to Have

• Apache Avro.
• Azure DevOps.
• SQL Server, MongoDB/Cosmos, and MariaDB.
• AI-augmented test generation/maintenance tooling.
• Chaos-engineering or fault-injection tooling.
