EGS is seeking a Specialty Mechanical Engineer to join our team at the Y-12 National Security Complex in Oak Ridge, TN, which provides integral mission support to the NNSA.

This position is full-time and will serve the Y-12 National Security Complex in Oak Ridge, TN.


Specialty Mechanical Engineers will produce design and procurement documents of specialty and first of a kind equipment. Equipment examples include gloveboxes, furnaces, high vacuum systems, gas transfer/analysis systems, process skids, metal casting, and machining equipment.

To be successful in this position, applicants should have experience and future career interests in the following skills/subject areas:


Produce a variety of design output documents including but not limited to systems requirements documents, calculations, drawings, bills of materials, specifications, datasheets, inspection plans, assembly instructions, and test plans/procedures.
Ensure design outputs are of sufficient detail for use by the end user/design requestor.
Develop build to print design drawings. This may be self-performed for small tasks, or directing and checking the output of mechanical designer(s) for larger scopes.
Strong understanding of 3D CAD modeling software and drawings
Consistent application of product numbering, drawing structure, and drawing numbers
Use of drafting standards such as ASME Y14.100 or the Drawing Requirements Manual
Application of ASME Y14.5 for dimensional tolerances and inspection criteria
Tolerance stack-up and error analysis calculations
Prepare calculations and analyses associated with machine design (to include, but not limited to, finite element analysis, structural and seismic analysis, ergonomic studies, kinematic calculations and heat transfer calculations).
Develop detailed equipment specifications and data sheets.
Manage project requirements, including extraction of requirements from higher level design criteria, the definition of applicable functional and operational requirements, flow-down to design documents & procurement specifications, and verification matrix activities prior to equipment startup.
Select materials which are compatible with corrosive gases and solutions.
Possess general shop experience with metal cutting tools and sheet metal fabrication (e.g., mills, lathes, wire EDM, bending, water/laser cutting, etc.).
Design fixtures and tooling for part fabrication, inspection, and assembly.
Apply welding, non-destructive examination, and leak checking code references, symbols, and notes in accordance with AWS and/or ASME standards.
Define and document the acceptance criteria, inspection plans, and testing required to qualify equipment and components.
Perform technical evaluations to disposition non-conformances, respond to request for waivers/deviations, and manage engineering change packages.
Conduct technical evaluations of custom and off-the-shelf components to identify attributes which are critical to performance.
Support technical evaluations of structures, systems, and components to identify items relied on for safety (IROFS).

Group/Project Coordination:

Create pre-project documents, including statements of work, cost estimates, and sequencing of design outputs for project scheduling.
Support procurement activities by preparing and reviewing contract documents and coordinating with procurement officers.
Integrate equipment into existing facilities, including interface control documents and coordinating tie-ins with facility engineering representatives.
Coordinate design reviews and design document transmittals.
Plan and direct engineering personnel in the fabrication of equipment and test-control apparatus (Heat-Transfer Engineers, Control and Instrumentation Engineers, or Hydraulic Engineers; Product Design Engineers or Test Engineers when mechanical engineering principles are primarily used).
Support the fabrication, installation, testing, readiness, and startup of custom designed equipment.
Promote a professional code of conduct and ethical behavior.
Provide technical direction and trouble-shooting skills.
Lead small design teams.
Provide direction to designer/drafters.
Perform peer-review or formal design verification of design output documents.


Promote a strong security culture. This involves understanding how to produce design outputs in/with areas, computers, and communication channels which have multiple levels of security control.
Perform design scope on sensitive projects while maintaining excellent. communication with the classification office, derivative classifiers, reviewing officials, and high-risk property management.
Communicate the importance of protecting proprietary or sensitive information and complying with cybersecurity policies and guidelines.


Maintain configuration management of design outputs through project data management systems, to ensure revision control and change control activities/workflows.
Perform design activities in accordance with documented design procedures, processes instructions, and forms (e.g.: Design Control, Design Reviews, Design Verification, Requirements Management, and Change Control Procedures).
Perform verification matrices to ensure design criteria and requirements have assigned acceptance criteria, including documented inspection plans, vendor surveillance, and criteria for the disposition of non-conformances.

Required Qualifications:

B.S. Degree from an ABET accredited Engineering program, a minimum of 10 years' experience with design/specification of custom mechanical equipment.
Hours will be 06:00 - 16:30, Monday through Thursday on-site at Y-12 in Oak Ridge, TN.
Successful drug screening.
Must be eligible to obtain and maintain a security or clearance badge.

Preferred Qualifications:

B.S. Degree from an ABET accredited Engineering program plus 20 years plus of direct experience.
Active Q Clearance Preferred.
CREO 3D CAD experience.
ANSYS FEA experience.
Glovebox design experience.
American Glovebox Society standards of practice & guidelines experience.
Design experience with custom industrial equipment and process skids on government projects.
