• Use machine tools, power tools, and hand tools.
• Provide general technical support for sample preparation and sample analysis.
• Acquire and analyze data, and develop solutions and alternative approaches to moderately complex mechanical problems using creativity and judgment.
• Maintain system documentation and experimental records.
• Follow written operational and safety procedures.
• Perform all assignments in accordance with safety and security requirements and policies.
• Perform other duties as assigned.

Additional job responsibilities, at the 533.3 level:

• Provide advanced technical support by applying fundamental knowledge of fabrication, assembly, installation, and system operation under minimal supervision.
• Interact regularly and independently with project leads, scientists, engineers, and technical personnel.
• Identify, evaluate, and analyze requirements and processes.
• Solve complex mechanical and operational problems.

Qualifications:

• Ability to obtain and maintain a U.S. DOE Q-level security clearance, which requires U.S. citizenship.
• Associate degree in engineering, mechanical, industrial, or manufacturing technology, or an equivalent combination of education and related experience.
• Experience with metallurgical sample preparation techniques, including mounting, sectioning, fine polishing, and etching.
• Experience making independent decisions regarding moderately complex technical problems.
• Demonstrated proficiency in written and verbal communication, and the interpersonal skills necessary to communicate effectively.
• Demonstrated ability to organize work, manage conflicting tasks, and interact effectively with team members.
• Experience with personal computers and associated software (Microsoft Office Suite).
• Ability to work in a multidisciplinary team environment.

Additional qualifications at the 533.3 level:

• Advanced knowledge of general manufacturing techniques.
• Significant experience operating and maintaining conventional and NC equipment.
• Experience with complex mechanical fabrication and assembly.

Qualifications We Desire:

• Familiarity with advanced optical microscopy techniques, including polarized light, differential interference contrast, and confocal microscopy.
• Familiarity with image analysis techniques, including grain size determination and measurement methods for determining phase fractions.
• Knowledge of materials processing, including welding.

Pay Range $43.55 - $63.97 Hourly $43.55 - $53.36 Hourly for the 533.2 level $52.23 - $63.97 Hourly for the 533.3 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.
