Summary:

As a Manufacturing Engineer, you will be responsible for the technical health, reliability, and continuous improvement of assigned manufacturing processes. You will work directly with production personnel to diagnose process and equipment problems, restore production when interruptions occur, reduce recurring failures, and improve manufacturing safety, quality, delivery, productivity, and cost.

APT’s manufacturing processes include zone refining of boride materials and tungsten; micromachining and shaping of lanthanum hexaboride and cerium hexaboride crystals; Schottky emitter assembly; cathode and electron-gun module assembly; tungsten etching; high-voltage conditioning; and cathode and module testing.

The successful candidate will develop sufficient knowledge of these processes to serve as a dependable technical resource when problems arise. This requires strong engineering fundamentals, hands-on mechanical and electrical aptitude, experience with vacuum systems and high voltage, disciplined troubleshooting skills, and the ability to work calmly but urgently during line-down situations.

A Manufacturing Engineer will also identify and implement process improvements, develop and maintain manufacturing documentation, support the company’s Quality Management System, and help transfer new or modified products and processes into production.
 

Essential Responsibilities

Manufacturing Process Ownership

• Provide engineering support for complex manufacturing processes, equipment, materials, testing, and product assembly operations.

• Establish process controls, operating procedures, testing requirements, and reaction plans to ensure consistent production performance.

• Train and support production personnel on manufacturing processes, troubleshooting techniques, and process improvements.

Continuous Improvement

• Identify and implement opportunities to improve safety, quality, productivity, capacity, yield, and cost.

• Lead process improvement initiatives using engineering principles, data analysis, Lean manufacturing, and continuous improvement tools.

• Monitor and analyze manufacturing metrics, identify sources of variation and waste, and implement sustainable solutions to improve process capability and performance.

• Conduct workflow analyses, capacity studies, and line-balancing activities to optimize manufacturing operations.

Quality Systems & Documentation

• Develop, maintain, and update manufacturing documentation, including procedures, work instructions, specifications, process controls, test methods, and training materials.

• Lead or support engineering change processes, corrective and preventive actions (CAPAs), nonconformance investigations, risk assessments, and process validations.

• Execute equipment and process qualification activities, ensuring all changes are properly documented, validated, approved, and implemented.

• Support internal and external audits and maintain accurate, traceable engineering records.

Equipment & Manufacturing Systems

• Design, develop, improve, and maintain manufacturing equipment, tooling, fixtures, test systems, and process controls.

• Troubleshoot and resolve electrical, mechanical, vacuum, thermal, instrumentation, and automation-related equipment issues.

• Support equipment procurement, installation, qualification, maintenance, reliability improvement, and automation initiatives.

• Ensure equipment and tooling meet safety, quality, ergonomic, and production requirements.

New Product Introduction & Process Transfer

• Support new product development, prototype builds, pilot production, and transfer of products into manufacturing.

• Collaborate with R&D to establish production processes, specifications, test methods, acceptance criteria, and process controls.

• Develop manufacturing documentation, tooling, training, and validation requirements to ensure successful product launches and process transfers.

Cross-Functional & Supplier Collaboration

• Partner with Production, Quality, R&D, Sales, leadership, suppliers, and customers to resolve technical issues and drive continuous improvement.

• Support supplier quality improvement, specification development, material investigations, and corrective actions.

• Foster strong working relationships with production teams and leverage operator expertise to improve manufacturing performance and reliability.

Requirements:

• Bachelor’s degree in manufacturing, Mechanical, Electrical, Materials, Process, Industrial, Systems, Applied Physics, or a closely related engineering discipline.

• Minimum of 5 years of relevant professional experience in manufacturing, process engineering, equipment engineering, product engineering, or a similar technical role.

• Experience supporting technically complex manufacturing processes in a production environment.

Necessary Skills:

• Working knowledge of vacuum science and vacuum-system operation, including pumps, gauges, seals, leak detection, contamination control, and vacuum troubleshooting.
