- Use AI-assisted coding tools and software engineering agents for test generation, test-data creation, mocks, stubs, failure analysis, refactoring, and documentation.
- Review AI-generated test code for correctness, security, maintainability, coverage, and engineering-standard alignment.
- Validate asynchronous processing, state transitions, retries, timeouts, duplicate requests, message ordering, idempotency, backpressure, and partial-failure recovery.
- Integrate automated tests into CI/CD pipelines and define quality metrics, release-readiness criteria, and actionable feedback.
- Partner with developers, architects, product teams, and mission teams to convert requirements and service contracts into executable tests.
- Mentor others in test-first engineering practices.

- Strong hands-on experience with software test automation for backend microservices, REST APIs, event-driven systems, and cloud-native applications is preferred.
- Experience testing Java 17+ and Spring Boot services with tools such as JUnit, Mockito, Testcontainers, WireMock, REST Assured, and Cucumber is preferred.
- Experience with AWS, Docker, Kubernetes, CI/CD pipelines, Kafka or similar messaging platforms, and automated test-environment or test-data setup is preferred.
- Experience with AI-assisted coding platforms such as GitHub Copilot, Claude Code, or Cursor, including context structuring, verification criteria, human review, and responsible AI controls, is preferred.
- Understanding of API contracts, state management, asynchronous processing, retries, idempotency, observability, resiliency, performance, and security testing is preferred.
- Experience creating reusable mocks, stubs, simulators, service virtualization, and integration-test harnesses is preferred.
- Experience with autonomy, robotics, machine integration, industrial systems, simulation-based testing, Software-in-the-Loop, Hardware-in-the-Loop, or Python-based test tooling is preferred.
