Embedded Software Verification & UI Programmer

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)., * Develop User Interface (UI) using Python Tkinter library

• Developing controls/monitoring software, low-level requirements-based tests to generate full-coverage LDRA verification procedures.
• Analyzing and dispositioning structural coverage holes.
• Coordinating with the customer to ensure full test coverage, correct expected results, and communication/disposition of test findings.
• Executing the tests in the LDRA test setup on both simulated and on-target environments.
• Reviewing test results and test time history data, during test development, regression runs, and to help debug software issues.
• Identifying findings to the customer in instances where test outcomes do not align with requirements or with expected results.
• Authoring and participating in formal reviews of test cases, procedures, and results.

Do you have experience in User-facing feature development?, Do you have a Master's degree?, * Bachelor's or Master's degree in aerospace engineering, electrical engineering, software engineering, or a related technical field.

• Experience developing Python UI using Tkinter or similar libraries (pySide, pyQt, wxPython, etc)
• Experience performing low-level software requirements-based testing under DO-178B/C or other safety-critical process standards
• Experience testing with LDRA or a similar tool (i.e. VectorCAST)
• Proficiency in understanding C programming, preferably with experience developing C code.
• A general understanding of control laws and redundancy management

Preferred Qualifications:

• Commercial controls industry experience or other embedded software development experience
• 5 years developing embedded software in safety-critical systems
