MechanicalManufacturing Engineer

We have an opening for a Mechanical/Manufacturing Engineer to join our Manufacturing Engineering and Technology Development Group. You will apply engineering principles to contribute to and/or lead projects supporting stockpile stewardship programs. These efforts will include the planning and execution of strategies of new and existing technologies ranging from additive manufacturing to dimensional metrology. You will become familiar with the ongoing priorities of the programs being supported to assist in developing proposals for future technology development that aids in the success of program objectives. Projects may involve requirements that are beyond commercially available capabilities and solutions may require modifications to commercial tools or development of advanced tools and fabrication methods. When available technology is inadequate to meet current or future program needs forward thinking will be essential for envisioning directions for technology development. This position is in the Material Engineering Division (MED) within the Engineering Directorate.

This position requires full-time on-site presence due to the nature of the work.

This position will be filled at either level depending on your qualifications. Additional job responsibilities (outlined below) will be assigned if you are selected at the higher level.

You will

• Provide engineering solutions of limited complexity for the characterization and processes used in the fabrication of components including tooling design and procedure development.
• Perform inspection operations of limited complexity and interpret specifications and mechanical drawings.
• Develop and execute Design of Experiments (DoE) studies to optimize process parameters.
• Work with multiple disciplinary teams to achieve engineering goals.
• Perform engineering calculations to support design fabrication and operations.
• Analyze and interpret data and the methods used to collect it.
• Work independently under general direction and collaboratively as part of a team while adhering to defined practices and procedures.
• Present technical approaches project plans and documentation to peers and program managers.
• Utilize Manufacturing Executing System (MES) for data entry part tracking and manufacturing optimization.
• Perform other duties as assigned.

Additional Duties at the SES.2 Level

• Solve moderately complex to complex technical issues related to mechanical systems and manufacturing operations.
• Develop and maintain procedures and processes to ensure that work is up to safety and quality standards.
• Utilize rigorous error budgets kinematic (exact) constraint and other precision engineering principles to qualify processes provide quantified design enhancements as needed to meet capability requirements and oversee the fabrication and implementation of these designs.
• Develop and present research and development proposals.
• Represent additive manufacturing processes to internal stakeholders and designers providing technical support for development of components and hardware.

Qualifications :

• Ability to secure and maintain a U.S. DOE Q-level security clearance which requires U.S. citizenship
• Bachelors degree in Mechanical Engineering Manufacturing Engineering Materials Engineering or the equivalent combination of education and related experience
• Fundamental knowledge of engineering principles and technologies as well as their related application spaces
• Fundamental engineering knowledge associated with machining and inspection operations and experience interpreting specifications and technical drawings.
• Ability to work independently and collaboratively as part of a team with effective organizational and interpersonal skills.
• Sufficient verbal and written communication skills necessary to effectively collaborate in a team environment and present and explain technical information
• Experience with responsibility for research design analysis prototyping and early fabrication/assembly/test

Additional Qualifications at the SES.2 Level

• Comprehensive knowledge of engineering principles and technologies with demonstrated ability to apply these to both new and existing moderately complex processes/equipment.
• Proficient verbal and written communication skills necessary to effectively collaborate in a team environment and present and explain technical information
• Experience leading or contributing to design reviews.
• Broad applications of fundamentals of vacuum technology and Programmable Logic Controller (PLC).

Qualifications we desire

• Masters Degree in Mechanical Engineering Manufacturing Engineering or the equivalent combination of education and related experience.
• Experience in CAD/CAM programming (Solidworks Autodesk Netfabb Prusa Slicer EOSPrint Stratasys Insight Materialize Magics Fusion 360 Mastercam).
• Experience in L-PBF SLS FDM and/or SLA additive manufacturing.
• Experience in machining using lathes mills wire-edm band saws welding casting forming etc.
• Understanding of additive manufacturing workflows materials and post-processing methods.
• Experience handling classified documents parts and removable electronic media.
• Familiarity with ISO 9001 AS9100 or similar quality standards.
• Knowledge of Design of Experiments (DoE) metrology tools and statistical process control.
• Experience with welding equipment including GTAW (TIG) welding and robotic welders.
• Experience working with customized foundry and welding systems in a R&D environment and working with radioactive/fissile materials.

Pay Range:

$121830 - $185544 Annually
$121830 - $154500 Annually for the SES.1 level
$146340 - $185544 Annually for the SES.2 level

This is the lowest to highest salary we in good faith believe we would pay for this role at the time of this posting; pay will not be below any applicable local minimum wage. An employees position within the salary range will be based on several factors including but not limited to specific competencies relevant education qualifications certifications experience skills seniority geographic location performance and business or organizational needs.
