About This Role

We are looking for a systematic, detail-orientated, and proactive Embedded Software Test Engineer who has an interest in medical devices and in trying to break them! You would design and execute tests in support of our Class II cardiac monitoring devices and their supporting software infrastructure. In this role, you will act as an advocate for the quality of our software, both from the perspective of our patients and our internal customers, working primarily with firmware written in C and with C#/.NET windows desktop applications.

• Collaborate with members of R&D and Manufacturing, among other teams, to define and implement testing strategies.
• Develop written verification test protocols, then subsequently document and report test results to both functional and customer requirements - in a manner consistent with regulatory and internal standards.
• Review requirements and design documentation to ensure technical accuracy as well as testability; act as a quality advocate throughout the development process.
• Analyze and test field failures to establish repeatability before working with the development team to address the root cause, and verify the correction before release.

What We Want To See

• At least 5 years of software quality assurance experience.
• At least 3-4 years of experience in testing desktop tools and/or embedded systems/hardware.
• Experience with electronic test equipment (power supplies, DMMs, oscilloscopes, etc) and ability to troubleshoot electrical and firmware issues on circuits/hardware.
• Very good understanding of QA principles and processes.
• Particularly a familiarity with the software QA process in the medical device industry or other regulated environment (e.g., FAA, SEC, DoD, Title 21 CFR part 11), and the related verification, validation, and documentation requirements.
• Excellent analytical and problem solving skills, finding creative solutions as well as enjoying investigative and troubleshooting processes.
• Self-motivated with ability to work independently as well as collaboratively in cross-functional teams, potentially leading testing efforts for a given project.
• Effective written communication skills in presentation of methods and observations.

Ways to Stand Out

• Proficiency in Linux/Unix environment.
• Work experience in a firmware or software development role.
• Programming experience in one or more of the following languages: Python, C/C++, .NET/C#, MYSQL
