Nnsa Contractor information

What is an NNSA contractor?

NNSA contractors are private companies or organizations that work with the National Nuclear Security Administration (NNSA) to help manage, operate, and support its facilities and missions. These contractors provide expertise in areas such as nuclear security, nonproliferation, and science-based stockpile stewardship. They play a crucial role in ensuring the safety, security, and effectiveness of the U.S. nuclear weapons stockpile, often managing laboratories, plants, and sites under long-term agreements with the NNSA.

What are the key skills and qualifications needed to thrive as an NNSA contractor?

To thrive as an NNSA Contractor, you generally need a strong background in engineering, physical sciences, or cybersecurity, along with a relevant degree and often a security clearance. Familiarity with classified information systems, project management tools, and federal compliance standards is typically required. Excellent problem-solving, attention to detail, and strong collaboration skills help contractors navigate complex projects and communicate effectively with federal stakeholders. These skills and qualifications are crucial for ensuring national security objectives are met and compliance with strict government regulations is maintained.

What unique challenges might I encounter as an NNSA contractor, and how can I prepare for them?

As an NNSA contractor, you may face unique challenges such as navigating complex security protocols and adapting to evolving federal compliance requirements. The work often involves collaboration with multidisciplinary teams, including government officials, scientists, and engineers, which requires strong communication and adaptability. Additionally, balancing project deadlines with strict safety and confidentiality standards can be demanding. Preparing by familiarizing yourself with federal security regulations, honing project management skills, and developing a clear understanding of classified information handling will be highly beneficial.

What is the difference between Nnsa Contractor vs Nnsa Analyst?

AspectNnsa ContractorNnsa Analyst
CredentialsSecurity clearances, specialized certificationsSecurity clearances, technical certifications
Work EnvironmentProject-based, on-site or remoteOffice or field, analytical setting

Job description

Navarro Research and Engineering is recruiting an Electrochemical Engineer (3919) in Oak Ridge, TN. 

Navarro Research & Engineering is an award-winning federal contractor dedicated to partnering with clients to advance clean energy and deliver effective solutions for complex challenges in the nuclear and environmental fields. Joining Navarro means being a part of an exceptional team committed to quality and safety while also looking for innovative strategies to create value for the client's success. Headquartered in Oak Ridge, Tennessee, Navarro has active programs in place across the nation for DOE/NNSA, NASA, and the Department of Defense. 

Position Summary 

The Electrochemical Engineer will provide technical leadership and hands-on engineering support for industrial-scale electrochemical cell development, with emphasis on molten salt or other large-format electrochemical systems. This role will help fill a critical experience need in electrochemistry at scale, supporting design, testing, optimization, and integration of process equipment across multidisciplinary engineering teams. 

Responsibilities 

  • Develop and support electrochemical process concepts, cell designs, operating parameters, and scale-up strategies for industrial-sized electrochemical systems. 
  • Provide technical input on molten salt electrochemistry, cell configuration, electrode materials, reaction environments, power requirements, thermal management, and process performance. 
  • Support design integration with DC power systems, high-temperature vessels, furnaces, mechanical piping, instrumentation, controls, safety systems, and custom equipment fabrication. 
  • Plan, evaluate, and document electrochemical testing, commissioning, troubleshooting, data interpretation, and performance improvement activities. 
  • Identify technical risks, scale-up challenges, process constraints, equipment interface issues, and opportunities to improve reliability, safety, and performance. 
  • Collaborate with internal subject matter experts, engineers, designers, fabricators, vendors, and project leadership to advance technical objectives. 

Requirements

Requirements 

  • Experience with molten salts or experience designing, developing, operating, or scaling industrial-sized electrochemical cells. 
  • Strong electrochemical engineering knowledge, including cell design, electrochemical reactions, mass transport, current distribution, electrode behavior, process monitoring, and performance analysis. 
  • Ability to translate electrochemical process requirements into practical engineering inputs for equipment design, power systems, controls, and operations. 
  • Experience supporting laboratory-to-pilot or pilot-to-industrial scale-up, test planning, technical documentation, and multidisciplinary engineering integration. 
  • Ability to work in a complex technical environment requiring safety focus, technical rigor, quality documentation, and cross-functional communication. 

Preferred Qualifications 

  • Senior-level experience with molten salt electrochemistry, electrorefining, electrowinning, electrodeposition, electroplating, metallurgy, or high-temperature electrochemical processes. 
  • Experience supporting DOE, NNSA, nuclear, advanced energy, materials processing, chemical processing, or highly regulated research and development programs. 
  • Advanced degree in Electrochemical Engineering, Chemical Engineering, Materials Science, Metallurgical Engineering, or a related field is preferred. 

Education and Experience 

Bachelor's degree in Electrochemical Engineering, Chemical Engineering, Materials Science, Metallurgical Engineering, or a related discipline is preferred. Equivalent combinations of education, advanced technical training, and directly relevant electrochemical systems experience may be considered. 

Due to the nature of the government contract requirements and/or clearances requirements, US citizenship is required.
