Job description

Job Title: DMD Mechanical/Piping Design Engineer

Job Specialty: Core Engineering

What You'll Do

As an engineer in Division Managed Design (DMD), you will be responsible for upgrades, retrofits, and modifications to existing systems across the Y-12 complex. DMD engineers are in a unique position to work near-term small to medium scale projects with direct impacts to the Y-12 mission.

Piping Design Engineers are responsible for equipment and piping system designs including line sizing and pressure drop calculations. This will also involve the selection of piping components (e.g., valves, regulators, pumps, etc.).

Key Responsibilities

• Perform relief valve sizing calculations to ensure safety and compliance with industry codes and standards (e.g., ASME B31, API, and Boiler Pressure Vessel code).
• Perform walk-downs and inspections of process and utility piping systems.
• Prepare written reports, drawings/sketches, and technical documents (Equivalencies, P&IDs, data sheets, and bills of material).
• Utilize appropriate regulations, design codes, and standards, including ASME B31.1 and B31.3, ASTM, AWWA as well as other relevant industry standards.
• Plan and self-perform project tasks including scope development, design timelines, requirements, schedule, research, design review, and field verification.

Recommended Attributes

• Knowledgeable in industry piping codes such as ASME, ASTM, and AWWA.
• Experience with design in systems such as potable water and fire-protection supply systems, gas supply systems, acid and caustic fluids, brines, cryogenics, steam and condensate, chilled water systems, chillers, boilers, cooling towers, and vacuum systems.
• Experience with pipe routing and piping component selection.
• Technical knowledge of related engineering systems, applications of engineering and construction methods and materials, and engineering application of computers.
• Experience with Microstation or other CAD software.
• Ability to effectively communicate complex technical information, both written and verbal.
• Ability to work independently and as part of a multifunctional team.
• Ability to self-direct with minimal day-to-day supervision.
• Highly detail-oriented with a strong focus on accuracy and thoroughness in all tasks.

What You Can Expect

• Meaningful work and unique opportunities to support missions vital to national and global security
• Top-notch, dedicated colleagues
• Generous pay and benefits with a stable organization
• Career advancement and professional development programs
• Work-life balance fostered through flexible work options and wellness initiatives
• Bachelor of Science in Engineering/Physical Science [Chemistry, Physics, or related] from an Engineering Accreditation Commission (EAC) Accreditation Board of Engineering and Technology (ABET) accredited program in the United States or designated equivalents from Canada or Mexico, the Washington Accord, or the list of substantially equivalent as documented by ABET AND 4 years of relevant experience. OR MS in Engineering /Physical science AND 2 years of relevant experience. OR PhD in Engineering /Physical science.
• There is a minimum Grade Point Average (GPA) requirement up to 4 years post-graduation at time of offer and confirmed by transcript. Beyond four years from graduation, engineering experience will supersede GPA as a requirement for hire.
• 3.5 minimum cumulative GPA for PhD
• In addition, the applicant must meet the requirements of DOE O 426.2A (i.e., Baccalaureate in engineering or related scientific major 2 years job-related, and 1-year nuclear experience; or a DOE O 426.2A alternative). DOE 426.2A experience requirements can be satisfied following employment. In the interim, newly hired personnel will not be assigned duties that could impact the safety basis of nuclear facilities. (Ref. DOE O 426.2A)
• Demonstrated experience in piping system design across diverse applications (e.g., boilers/steam, potable/hot/chilled water, compressed gases, cryogenics, vacuum, caustic/acid)
• Proficiency in pipe routing, component selection, and strict adherence to ASME B31.1 and B31.3 codes including owners inspection requirements
• Knowledge of industry codes (ASME, ASTM, AWWA) and relevant quality programs (ASME NQA-1, 10CFR 830.120)

Preferred Job Requirements

• Experience with CAD modeling, particularly using Bentley software
• 10+ years of experience
• A Professional Engineering License (PE)
