About The Position

This lead-level Mechanical Engineering position offers challenging work and career advancement opportunities. The role leads mechanical design engineering efforts on multidisciplinary project teams, applying mechanical engineering expertise to special-purpose equipment, pressure vessels, and interfacing systems, controls, and structural support elements. The position includes technical oversight of assigned staff, preparation and review of calculations, designs, specifications, and reports, and responsibility for managing assigned work to schedule and budget. It also involves direct customer interaction, vendor communication, and mentoring junior engineers. The position supports Sargent & Lundy’s Government Services Division, which provides engineering design and consulting services to U.S. Department of Energy sites and national laboratories, including DOE Environmental Management and National Nuclear Security Administration locations. Projects may involve cleanup of legacy nuclear weapons production sites or support for the country’s nuclear deterrent, including facilities, systems, and equipment for treating, storing, and disposing of nuclear waste and safely handling and processing nuclear material. The role allows a hybrid arrangement with a mix of work from home and in the office. Candidates must be U.S. citizens; dual citizenship with a country other than the U.S. does not qualify. The selected candidate must be able to obtain a U.S. Government security clearance.

Requirements

U.S. citizenship; dual citizenship with a country other than the U.S. does not qualify.
Ability to obtain a U.S. Government security clearance.
BSME or MSME from an ABET-accredited engineering program, with a strong academic background and interest in thermodynamics, heat transfer, fluid mechanics, machine design, or thermal systems.
12+ years of progressive, responsible experience in mechanical engineering, ideally in a nuclear environment.
Experience producing engineering designs and analyses for piping, pressure vessels, HVAC, and/or radioactive material handling systems.
Working knowledge of codes, standards, and regulations applicable to mechanical engineering design, such as ASME B31 piping codes, ASME Boiler & Pressure Vessel Code, and ASME AG-1.
Experience with Finite Element Analysis or advanced engineering software, such as ANSYS, AutoPIPE, Datacor/AFT flow simulation, Hourly Analysis Program, or Trace 700.
Excellent written and verbal communication skills.
