Requirements

5–10+ years of hands-on experience with electron beam systems
Strong understanding of EB system architecture, including high-voltage power supplies, vacuum systems, beam optics and alignment, as well as motion and control integration
Proven ability to troubleshoot complex system-level issues
Experience in commissioning, service, or applications engineering roles
PLC experience (diagnostics and adjustments; programming not required)
Strong communication skills and ability to train others
Willingness to travel approximately 30–40%

Nice To Haves

Experience with additive manufacturing systems
Experience mentoring or leading technical teams
Familiarity with Siemens (TIA Portal, drives, etc.)
