Electrical Maintenance Engineer - Electron Beam Systems

Department: Engineering / Maintenance / Manufacturing

The E-Beam Systems Electrical Maintenance Engineer is responsible for the preventative and corrective maintenance, troubleshooting, and performance optimization of our electron beam equipment. This role requires a deep understanding of high-voltage systems, vacuum technology, precision analog/digital controls, and industrial automation. The ideal candidate will be a hands‑on problem‑solver who ensures maximum equipment uptime and process stability through rigorous electrical engineering practices and an unwavering commitment to safety.

• Develop, execute, and continuously improve preventative maintenance (PM) schedules for all E-Beam subsystems.
• Perform hands‑on troubleshooting and root cause analysis for electrical and electro‑mechanical system failures.
• Repair and replace faulty components, including high‑voltage power supplies, lens/deflection amplifiers, vacuum pump controllers, PLC modules, and sensors.
• Maintain meticulous records of all maintenance activities, failures, and solutions in the computerized maintenance management system (CMMS).

• Maintain and troubleshoot high‑voltage power supplies for the electron guns, and filament circuits.
• Safely perform high‑voltage DC measurements and discharge high‑energy capacitors using established LOTO procedures.

• Maintain and troubleshoot the vacuum system, including roughing pumps, turbo‑molecular pumps, pressure gauges (Pirani, Cold Cathode), and pneumatic valves.
• Support the cooling water system, ensuring proper flow, temperature, and resistivity of de‑ionized coolant.
• Collaborate with mechanical and vacuum technicians on complex, multi‑disciplinary issues.

• Troubleshoot and program PLCs (e.g., Siemens) and HMIs for equipment control and sequencing.
• Diagnose and repair issues with safety interlock circuits (door switches, water flow, vacuum level).
• Utilize schematics, wiring diagrams, and ladder logic to diagnose control system faults.

• Serve as a subject matter expert on E‑Beam safety, including high‑voltage and X‑ray hazards.
• Rigorously enforce and adhere to Lock‑Out/Tag‑Out (LOTO) procedures.
• Ensure all work complies with company safety policies and industry regulations.

• Education: Bachelor of Science in Electrical Engineering, Electronics Engineering, or a related field. Equivalent military training or an Associate's degree with significant direct experience may be considered.
• Experience: Minimum of 3-5 years of hands‑on experience maintaining and troubleshooting complex capital equipment in a manufacturing or R&D environment.
• Technical
