Position Summary:

JGMS is looking to hire an applied mechanical engineer who provides applies their skills for a novel advanced reactor design project. Apply engineering principles to the solution of mechanical problems as they relate to reactor design activities. Mechanical problems are those that are related to the motion and dynamics of heat, gas, air, fluids, and solid materials required to design nuclear reactors and systems that function in a safe and reliable, efficient, and predictable manner. Must be proficient in designing systems in accordance with relevant national consensus codes and standards such as ASME B31 series and BPVC. 

This is a 6-month temporary assignment with possibility for extension. This position is fully remote and requires travel to the client site in Idaho once a month for the duration of the contract. This role operates on a 4 x 10 schedule; expected work hours are Monday through Thursday, from 7:00 AM to 5:00 PM Mountain Time.

Job Duties and Responsibilities:

• Demonstrated ability to work with a multi-disciplinary team of scientists and engineers on a novel advanced reactor design. 
• Demonstrated effectiveness at system design and evaluation. 
• Demonstrated effectiveness with project completion and implementation. 
• Experience with high temperature springs 
• Proven experience with design of safety related steel and concrete nuclear structures. Experience with shielding systems is preferred. 
• Proven experience with design of pipe supports in accordance with ASME B31. 
• Document the design of electromechanical devices (controlled and approved models, drawings, specifications, design descriptions) such as control rod/drum drive mechanisms to establish conformance with design requirements and applicable codes and standards. 
• Decompose project objectives into defined and controlled design requirements using a systems engineering approach and applying digital engineering tools for tracking requirements and design parameters. 
• Use design methodologies, technologies, and processes which are best practice for the technical discipline to develop and define a design, and to validate that the design meets defined requirements. 
• Establish testing, inspection, and quality requirements to ensure technical features important to design functions are maintained. 
• Oversee or otherwise ensure that fabrication, construction, assembly, and procurement are done in accordance with the design. 
• Ensure any design meets the technical baseline requirements and applicable codes and regulations. 
• Develop, ensure adequacy of, and maintain configuration management of the technical baseline. Establish and maintain configuration management of assigned system. 
• Ensure consistency in operation characteristics among applicable documents such as drawings, technical manuals, operating instructions, emergency operating procedures. 
• Work with other designers, customers, and analysts to develop experiment requirements, perform conceptual and final designs, follow all fabrication and inspection activities, lead experiment assembly activities, support installation and testing of experiments, and support development of integrated analyses to ensure that facility safety bases are met.
• Responsible for design and fabrication and associated activities leading to reactor operations and experimentation. 
• Other duties as assigned by the Lead Reactor Project Engineer or the Engineering Manager. 

Required Qualifications:

• Bachelor of Science degree in mechanical engineering or a directly related field, with a minimum of 8 years of relevant experience; or a Master of Science degree in mechanical engineering or a directly related field, with a minimum of 6 years of relevant experience. The qualifying degree must be from an ABET-accredited program. 
• Knowledge of design techniques, tools, and principles involved in production of precision technical plans, blueprints, drawings, and models. 
• Knowledge of the practical application of engineering science and technology. This includes applying principles, techniques, procedures, and equipment to the design and production of various goods and services. 
• Ability to apply general rules to specific problems to produce answers that make sense. 
• Ability to combine pieces of information to form general rules or conclusions (includes finding a relationship among seemingly unrelated events). 
• Ability to listen to and understand information and ideas presented through spoken words and sentences. 
• Ability to communicate information and ideas in speaking so others will understand. 
• Ability to tell when something is wrong or is likely to go wrong. It does not involve solving the problem, only recognizing that there is a problem. 
• Must be a United States Citizen.
• The candidate may work remotely but must be available to travel to client site as required.
