Engineer II - Quality Engg & AI

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 Nice to Have Prior experience testing hardware-integrated or device-simulator-driven systems (pharmacy automation, IoT, industrial control, or similar domains) Familiarity with chaos engineering principles (steady-state verification, fault injection, recovery validation) Healthcare/pharmacy domain exposure, including PHI-awareness in logging and data handling Experience with resilience/reliability testing patterns (retry logic, watchdog timers, connection recovery)
