Work Environment This role offers a primarily remote work arrangement, complemented by periodic travel to nuclear plant sites and office locations as project needs dictate. You will work in a highly regulated nuclear industry environment that emphasizes safety, quality, and compliance with strict procedures and standards. Site visits may involve working in operational commercial nuclear facilities, w you will follow established access, security, and safety protocols and collaborate closely with plant personnel and multidisciplinary engineering teams. The position involves regular use of advanced engineering software tools such as Auto

PIPE, CAESAR II, ANSYS

Mechanical, and ANSYS Fluent, as well as other analysis and documentation systems commonly used in nuclear and heavy industrial projects. Travel is expected to be approximately 25% of the time to support onsite work, client meetings, and coordination with project teams, while the remote component allows focused analytical and design work in a professional office setting.
