Quest Defense Systems and Solutions is seeking highly skilled Software Verification & Validation Engineers to perform requirements-based unit tests for embedded software on a nuclear power plant control system. The NQA-1 safety standard governs the project, 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.ย
This role is remote.ย
Key Responsibilities:ย
- Developing controls/monitoring software, low-level requirements-based tests to generate full-coverage LDRA verification procedures.ย
- Analyzing and dispositioning structural coverage holes.ย
- Coordinating with the customer to ensure full test coverage, correct expected results, and communication/disposition of test findings.ย
- Executing the tests in the LDRA test setup on both simulated and on-target environments.ย
- Reviewing test results and test time history data during test development, regression runs, and to help debug software issues.ย
- Identifying findings and reporting them to the customer when test outcomes do not align with requirements or with expected results.ย
- Authoring and participating in formal reviews of test cases, procedures, and results.ย
Required Qualifications:ย
- Bachelor's or Master's degree in aerospace engineering, electrical engineering, software engineering, or a related technical field.ย
- 5 years performing low-level software requirements-based testingย
- 2 years testing with LDRA or similar tool (i.e., VectorCAST)ย
- Proficiency in understanding C programming, preferably with experience developing C code.ย
- Emphasis on Python development, especially UI building with Python.ย
- Experience doing requirements-based testing under DO-178B/C or other safety-critical process standards.ย
