QA Automation Engineer

Key Responsibilities

• Design and implement a NUnit based automation framework to drive test execution against simulator
• Build reusable service-layer components: TCP/socket connection handling, XML message construction and parsing, database state verification (polling Rx status/reason against expected values within timeout), and structured logging
• Automate test cases
• Implement fault-injection scenarios for Resilience & Chaos suites (connection drops, malformed/oversized messages, duplicate ACKs, timeout/watchdog behavior) and validate structured log output as a pass/fail criterion
• Integrate the automated suite into a CI/CD pipeline (GitHub Actions) with phase-gated execution
• Maintain a requirement-to-test-case traceability matrix
• Flag and document the small set of manual-only cases that fall outside automation scope
• Work within a compressed timeline prioritize a working, CI-gated regression suite over exhaustive tooling polish

Required Skills

• 4+ years hands-on test automation experience, with strong C# and NUnit 3 (or equivalent xUnit-family framework) expertise
• Solid experience with TCP/socket-level programming and XML message-based integration testing (not just REST/HTTP)
• Experience building or extending a layered/service-oriented automation framework (not just writing flat test scripts) comfortable with concepts like connection/auth abstraction, database verification services, and fault-injection harnesses
• Working knowledge of CI/CD pipelines, ideally GitHub Actions
• Familiarity with database validation (SQL queries, polling for state transitions with timeout logic)
• Comfortable working against a fixed, aggressive delivery timeline with minimal ramp-up time
