## Description

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.
