Lead Mechanical Engineer

Company Description

Raven-Flint is dedicated to strengthening U.S. leadership in the nuclear industry by delivering critical uranium conversion services for advanced reactors. The company focuses on closing a key gap in the nuclear fuel supply chain as global demand for clean, reliable energy increases. While new reactors are being developed worldwide, existing conversion infrastructure has not kept pace with these advancements. Raven-Flint is building next-generation conversion facilities designed to be safer, more cost-effective, and faster to deploy.

Team members contribute directly to a mission that supports energy security and innovation in nuclear technology.

This is a full-time, on-site Lead Mechanical Engineer role based in Idaho Falls,  Lead Mechanical Engineer will oversee the mechanical design and development of equipment and systems for uranium conversion facilities, from concept through detailed design and implementation. Responsibilities include leading mechanical engineering activities, performing calculations, reviewing drawings and models, and ensuring designs meet safety, regulatory, and performance requirements. The role involves directing and mentoring other engineers, coordinating with cross-functional teams (process, electrical, controls, safety, and operations), and managing technical interfaces with suppliers and contractors.

Day-to-day work includes creating and reviewing CAD models and mechanical layouts, supporting R&D efforts on new equipment and processes, resolving technical issues during fabrication and installation, and contributing to project planning, scheduling, and risk management. The Lead Mechanical Engineer will also help develop and maintain engineering standards, documentation, and best practices for the organization.
