Additional Information

What we do matters. We are a high-growth, agile company creating safety and mission-critical solutions in a synergistic environment between our people and our client partners. From F-35 and F-16 fighter jets to the latest aviation technologies to medical devices, spacecraft, and satellites - our engineers have worked on some of the coolest Aerospace, Defense, Space, and Medical Device products in the world. Be a part of the team that is powering engineering solutions that drive technology. Quest Defense Systems and Solutions is seeking highly skilled Software Engineers to perform requirements-based unit tests for embedded software in a nuclear power plant controls system. Additionally, the engineer will use Python to develop User Interface (UI) for a software verification tools. The project is governed by the NQA-1 safety standard, a quality assurance framework for nuclear facility applications. Testing should be performed with a safety and completeness mindset prescribed by DO-178. However, NQA-1 is less prescriptive, acting as a high-level quality framework, and less structured. Comprehensive testing is required (MCDC coverage). Due to the nature of the project, all applicants must be U.S. Citizens or US lawful permanent residents. This role is preferred onsite/hybrid in Wilmington, NC.
