Key Responsibilities:
· Analyze firmware requirements, architecture, C/C++ source code, design principles, and existing test procedures to identify test scenarios, establish expected behavior, and develop automated tests with clear requirements traceability
· Adapt C/C++ firmware and its operating system and hardware interfaces to support host-based SIL execution
· Develop and maintain Python test scripts, reusable libraries, hardware simulations, and test utilities within the existing SIL framework, extending the framework to support additional subsystems and products
· Develop positive, negative, boundary-condition, and fault-injection tests covering functional behavior, interfaces, fault handling, recovery, and state transitions, including timeouts, sequencing, and concurrency-related behavior within SIL capabilities rather than assuming target-equivalent execution timing
· Run tests, assess results, reproduce defects, and investigate failures throughout the firmware, interface adaptations, simulations, framework, and test code to distinguish product defects from test-environment issues
· Integrate tests with Azure DevOps (ADO), GitHub, and CI workflows
· Collaborate with embedded software, systems, architecture, verification, and quality engineers to improve testability
· Develop repeatable, isolated tests with reliable setup and cleanup, clear assertions, versioned firmware and test configurations, review records, and retained results to support regression testing and use in formal verification
· Improve framework reliability, simulation fidelity, execution efficiency, and test coverage; identify differences between simulated and target behavior that could affect test validity
Key Requirements/Minimum Qualifications:
· Bachelor’s or Master’s degree in Computer Engineering, Electrical Engineering, Computer Science, or related field
· 8–10 years of relevant experience grounded in hands-on embedded software/firmware development; experience limited to general software automation or SDET work is not a substitute for this foundation
· Strong embedded C/C++ firmware development experience and understanding of firmware architecture, design principles, microcontrollers, peripherals, hardware interfaces, platform software, and abstraction layers
· Hands-on experience with real-time operating systems (RTOS) and OS abstraction concepts
· Demonstrated ability to learn new programming languages and tools, and willingness to build Python proficiency for test automation, framework extensions, and hardware simulation
· Experience developing automated tests for embedded systems and using firmware design and source-code analysis to select test scenarios and investigate failures; prior SDET job experience is not required
· Good understanding of real-time system fundamentals, including scheduling, interrupts, concurrency, timing behavior, communication interfaces, and fault handling
· Experience with medical device software development and IEC 62304 lifecycle practices
· Knowledge of risk-based verification, requirements traceability, configuration management, and objective test evidence
· Familiarity with Python, particularly for test automation or engineering tools
· Experience with pytest, test doubles, mocking, hardware simulation, and code coverage; familiarity with static analysis, CMake, or containerized test environments is a plus
· Prior exposure to SIL or hardware-in-the-loop (HIL) testing, or specific RTOS platforms such as ThreadX or FreeRTOS
· Experience improving an existing test automation framework
· Strong debugging, log analysis, root-cause analysis, and problem-solving skills
· Ability to develop clean and maintainable automation code
· Ability to work independently and collaborate with cross-functional teams
· Attention to detail, structured thinking, and strong ownership
· Ability to translate requirements and product risks into executable…
