Qualifications

• Bachelor's degree in Software/Engineering or related field.
• 6+ years of experience in software testing, test automation, verification, integration, or embedded systems development.
• Experience developing and maintaining automated system-level HIL test platforms, simulation environments, fault-injection frameworks, and CI/CD-integrated automated test solutions for complex embedded or electromechanical systems.
• Strong C# programming, test scripting, debugging, and software design skills.
• Experience testing embedded software and integrated hardware/software systems.
• Experience with CAN and CANopen networks, including configuration, monitoring, diagnostics, fault analysis, and validation of communications between embedded controllers, motor drives, sensors, actuators, and test systems.
• Hands-on electrical aptitude and experience building, wiring, instrumenting, and debugging test fixtures for software-controlled electromechanical systems.
• Experience with source control, defect management, and workflow tools such as Bitbucket, Azure DevOps, & Jira.

Responsibilities

• Define comprehensive software test strategies that verify requirements for functional, performance, reliability, fault-handling, and failure-mode scenarios across normal and abnormal operating conditions.
• Translate system requirements, user stories, and defect reports into executable test cases that include test scenarios, procedures, and acceptance criteria
• Identify test coverage gaps and develop plans to close them.
• Maintain traceability among requirements, test cases, results, and defects
• Influence product and software architecture to enable improved testability, diagnosability, safety, and robustness.
• Design, develop, and maintain automated test frameworks, test harnesses, reusable libraries, fixtures, and utilities.
• Validate end-to-end integration and interoperability of software, firmware, hardware, communications networks, simulated subsystems, and machine-level functions within automated system-level HIL test platforms
• Develop and debug C# test scripts for embedded controllers, robotic behaviors, communications, fault handling, and machine functions.
• Develop automated fault injection tests to evaluate software resilience.
• Develop fault-injection and negative-test methods to evaluate fault detection, recovery, and fail-safe behavior.
• Integrate automated testing, reporting, and quality gates into CI/CD and software release workflows.
• Establish metrics for test coverage, pass rates, defect trends, reliability, and release readiness.
• Evaluate AI-assisted tools for test generation, coverage-gap detection, debugging, and data analysis.
• Execute automated and manual tests across software configurations and product releases.
• Verify fault detection, fault handling, recovery behavior, and system safety functions.
• Validate communications, controller states, and machine response during abnormal operating conditions.
• Analyze test data and logs to identify trends, isolate failures, and determine root causes in collaboration with software developers and system engineers.
• Document defects with clear evidence, reproduction steps, risk assessments, and recommended actions.
• Troubleshoot issues across embedded software, networking, hardware integration, and automation systems.
• Expand & Execute automated regression coverage across multiple software releases.
• Present testing results and quality assessments to engineering leadership and project teams.
