Systems Engineer – Nuclear I&C / BWR

Join the elite team at QDSS, where our engineers are at the forefront of developing cutting-edge Aerospace, Defense, Space, and Medical Device products. Your work will make a real impact, contributing to the core of engineering solutions that drive technological advancements.

Quest Defense Systems & Solutions (QDSS) is seeking an experienced Nuclear Engineer to support the design, modernization, and modification of complex nuclear power plant systems. This role will work across multidisciplinary engineering teams to evaluate plant-level requirements, support system and subsystem design, and ensure proposed changes meet applicable safety, regulatory, licensing, and operational requirements.

The ideal candidate will bring strong nuclear power design engineering experience with specific knowledge of Boiling Water Reactor (BWR) plants. This position requires a systems-level understanding of how mechanical, electrical, instrumentation and controls (I&C), software, hardware, and FPGA-based systems interact within a nuclear power environment. Experience with reactor protection, nuclear I&C, plant modernization, and legacy GE BWR architectures is highly valued.

This role can be performed remotely from anywhere in the United States. Candidates must be US Citizens or US Permanent Residents.

What You’ll Be Doing

• Translate plant-level, operational, and nuclear safety requirements into allocated system and subsystem requirements.
• Decompose and allocate requirements across mechanical, electrical, hardware, software, FPGA, instrumentation, and control implementations.
• Develop, maintain, and review system descriptions, design specifications, interface requirements, Interface Control Documents (ICDs), cabinet drawings, elementary drawings, and connection/route drawings.
• Evaluate proposed changes to mechanical, electrical, process, instrumentation, control, protection, and safety systems.
• Support the development and review of engineering change packages and plant design modifications.
• Perform requirements quality, completeness, consistency, and traceability reviews.
• Participate in technical and design reviews, Technical Specification markups, and licensing-related reviews.
• Evaluate potential nuclear safety, design-basis, and licensing impacts associated with design changes.
• Support resolution of technical issues, test anomalies, nonconformances, and design discrepancies.
• Perform or support functional analysis, requirements analysis, Failure Modes and Effects Analysis (FMEA/FMECA), single-failure analysis, and design-basis evaluations.
• Collaborate with multidisciplinary engineering teams to ensure system interfaces and requirements are properly understood and implemented.
• Required Qualifications
• Bachelor’s degree in Nuclear, Systems, Mechanical, Electrical, Computer Engineering, or a related engineering discipline.
• 5+ years of nuclear power plant design engineering experience, preferably with GE-designed Boiling Water Reactors (BWRs).
• Solid knowledge of Reactor Protection Systems (RPS), Instrumentation & Controls (I&C), neutron monitoring, safety-related instrumentation, trip logic, and digital/analog control systems, including NUMAC or comparable GE platforms.
• Understanding of BWR design and licensing requirements, safety classifications, equipment/environmental qualification, seismic requirements, failure analysis, Technical Specifications, and surveillance requirements.
• Experience with engineering requirements analysis, FMEA/FMECA, single-failure analysis, and design-basis evaluations.
• Ability to assess plant system interactions, evaluate legacy GE BWR designs, support design changes, and document nuclear safety and licensing impacts.
• Strong technical writing, requirements development, and cross-disciplinary collaboration skills.

Preferred Qualifications

• Direct GE BWR design experience or previous GE Vernova / GE Hitachi engineering experience.
• Reactor protection, Emergency Core Cooling System (ECCS), digital I&C, NUMAC, or legacy GE I&C experience.
• BWR plant modifications, modernization, system safety, or failure analysis experience.
• Experience working under NQA-1 and 10 CFR 50 Appendix B quality programs.
• The QDSS Advantage: At QDSS, our advantage is purpose-driven work, collaborative teams, and complex challenges that push boundaries and build lasting impact. You’ll grow your career while contributing to mission-critical programs that demand excellence and shape the future.
