Quest Defense Systems and Solutions is seeking highly skilled Software Engineers to perform requirements-based unit testing for embedded software in a nuclear power plant controls system. 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 proscribed 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 US Citizens or US lawful permanent resident. This role is remote.

• 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.

• Bachelor’s or Master’s degree in aerospace engineering, electrical engineering, software engineering, or a related technical field.
• 5 years performing low‑level software requirements‑based testing.
• 2 years testing with LDRA or similar tool (i.e. Vector
  
  CAST).
• Proficiency in understanding C programming, preferably with experience developing C code.
• Experience doing requirements‑based testing under DO‑178B/C or other safety critical process standards.
• A general understanding of control laws and redundancy management.

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