Job Description:

Job Description Job Description Description: At SHINE Technologies, we are building the future of clean, limitless energy through next-generation nuclear fusion. As a fast-growing startup company, we thrive on solving some of the toughest challenges in science and engineering. We are a team of physicists, engineers and innovators working together to bring fusion energy out of the lab and into the grid. The Fusion Linear Accelerator for Radiation Effects (FLARE) team will operate and develop the linear accelerator and gas separation system reliability testing and performance projects, lead commissioning and qualification activities, identify and implement system improvements, perform R&D project testing, train new operators, and operate the system to support the FLARE business customers. The person will be responsible for operating the system to support internal system development projects and external customer radiation effects testing. They will be responsible for designing, executing, and evaluating experiments for radiation effects testing and system performance. All work will be performed in compliance with safety regulations. The Fusion Linear Accelerator & Gas Processing Test Engineer will also contribute to continuous improvements for the equipment and team processes. The base salary range for this position is $65,000 - $115,000 per year plus a comprehensive compensation package. Our salary ranges are determined by role, level, and location. Duties and Responsibilities: Complete required training and operate a neutron driver linear accelerator system and a tritium purification system in accordance with written procedures and plans. Participate in a training program that, upon successful completion, will result in a State of Wisconsin Radioactive Materials License Authorized User qualification. Design and conduct radiation effects tests using the linear accelerator and gas separation system. Design and execute experiments to test the performance and reliability of the linear accelerator and gas separation system. Evaluate the data to understand failures, recommend improvements, and implement improvements. Collect, analyze, and interpret experimental data to assess tritium usage, how it affects the equipment installation, and neutron output. Create and implement workplans that adhere to radiation safety procedures, maintenance operations and troubleshooting standards. Participate in facility readiness reviews, safety assessments, and system upgrades to enhance testing capabilities, including assessing how they will affect future equipment installation. Utilize test equipment to detect and measure radiation activity and understand the physics of the accelerator to troubleshoot and diagnose for performance optimization. Execute customer projects and collaborate with cross-functional teams to ensure customer requirements and timelines are met. Commitment to maintaining a strong culture of safety and compliance by adhering to all applicable radiation safety and protection, quality assurance, and environmental health and safety procedures, including but not limited to lock-out, tag-out, Requirements: Bachelor’s degree in Nuclear Engineering, Physics, Chemistry or Chemical Engineering is preferred.

Two or more years of relevant experience in radiation testing, nuclear engineering, or a related technical discipline (graduate research may be considered) with a deep understanding of general engineering principles and familiarity with radiation safety and applicable NRC or DOE regulations. Experience with data analysis and technical reporting using effective written and verbal communication skills. Proficiency with standard computer software and data analysis tools (e.g., MATLAB, Python), or equivalent is desirable. Experience with Monte Carlo radiation transport modeling (e.g., MCNP, FLUKA) is desirable. Working Conditions and Physical Effort: Ability to remain in a stationary position (e.g., standing or sitting) for extended periods. Ability to move within facility environments, including accessing testing areas and operating instrumentation. Ability to handle standard laboratory equipment and materials weighing up to 50 pounds with or without reasonable accommodation. Work may occasionally take place in controlled radiation areas under supervision and within regulatory exposure limits. Use of personal protective equipment (PPE), including full Tyvek suit while wearing a ventilated hood, lab coats, safety glasses, and dosimeters. Work involves moderate exposure to unusual elements, such as extreme temperatures, dirt, dust, fumes, smoke, unpleasant odors, and/or loud noises. Work environment involves some exposure to hazards or physical risks, which require following basic safety precautions. Although flexible work hours may be available, shift-work schedules may be required, and extended hours will sometimes be necessary to complete required work assignment. Able to obtain confined space entry certification. Exposure arc flash and high voltage usage. Participation in the site emergency plan drills. Eligibility for employment is conditioned on the applicant’s ability to qualify for access to information subject to U.S. Export Controls. Additionally, applicant’s eligibility may be conditioned based upon meeting the Nuclear Regulatory Commission requirements for access to Safeguards Information, which typically requires a pre-employment drug screen, fingerprinting and criminal background check.
