Edgewater Technical Associates is seeking qualified candidates for Nuclear Criticality Safety Engineer opportunities at various locations across the United States Department of Energy (DOE) complex in support of traditional environmental clean-up missions and in support of the advancement of first-in-kind commercial fuel capabilities at select sites across the United States.

Work Location: Varies from on-site full-time; hybrid with 1-2 weeks on-site at a time with business travel for on-site trips; and Edgewater regional office locations (i.e., remote).

Clearance Requirement: Ability to obtain DOE L or Q level clearance.

Citizenship: United States Citizenship required.

Edgewater Technical Associates, LLC (Edgewater) is a New Mexico-based small business headquartered in Los Alamos, NM, with five (5) regional offices across the United States to locally support their growing presence at project sites. Edgewater has a proven track record and is a trusted provider of fixed-price construction projects, engineering, and technical services for the DOE, DOD, National Nuclear Regulatory Commission (NRC), Canadian Commercial Nuclear Industry, and private sector commercial contractors involved in nuclear, high-hazard, or complex operations. Edgewater's experience and guidance ensure that its customers perform hazardous operations, comply with regulatory requirements, and maintain the highest quality and safety standards.

Candidate(s) will independently perform Nuclear Criticality Safety (NCS) analysis and design activities in support of DOE nuclear and commercial fuel cycle facilities, engineering programs, and projects. Utilizing basic and advanced engineering and NCS fundamentals, as assigned, perform criticality safety analyses to support new and existing design and licensing functions. Perform other engineering activities required to support facility design, configuration control, and operation. Candidate(s) will work in design safety basis organizations and depending on area of expertise will focus on criticality safety analyses, chemical dose consequence analyses, or shielding analyses.

Requirements:

• Have a Bachelors, Masters, or PhD in nuclear engineering, chemical engineering, or chemistry.
