Key Responsibilities
High-Power Laser Testing & Characterization (HP Mantis)
- Execute standard tests on the HP Mantis laser platform and generate detailed device performance reports.
- Characterize device performance to establish, rank, and maintain a clear inventory of backup devices for daily printing operations.
- Troubleshoot system issues as they arise, collaborating cross-functionally with the internal OE team and external vendors (e.g., Laserline) to implement solutions.
- Support the system setup, validation, and testing for the upcoming HP Mantis PL upgrade.
- Create and maintain accurate CAD drawings and assembly models for LV configurations, substrates, and engineering requirements.
- Author and maintain procedural documentation, standard operating procedures (SOPs), and internal documentation highlighting build process deviations.
- Act as the primary escalation point for cleanroom technicians, resolving issues related to daily tasks, LV builds, and quality inspections.
- Review post-build inspection images and log results into our Airtable database.
- Perform advanced consumable preparation beyond the scope of standard technicians, including precise mixing of alignment layers and epoxy materials.
- Maintain, troubleshoot, and fix LV processing equipment, including specialized tools, computers, and supplies.
- Support future development efforts for future cleanroom scoping
- Partner with the process engineering team to troubleshoot system-level 3D printer issues, actively isolating LV-specific failures from general system errors.
- Execute the mechanical removal, replacement, and housing integration of LVs, ensuring backup devices are correctly set up.
- Install new electro-optic devices into the printer systems and assist with system tuning, alignment, and calibration.
- Experience in an electro-optical, semiconductor, or laser systems manufacturing environment.
- Hands-on experience working in a cleanroom environment, specifically with sensitive optics, liquid crystal devices, or semiconductor wafers.
- Advanced Proficiency in CAD software for creating assembly models and configuration drawings.
- Experience executing DOEs and managing data tracking systems
- Strong mechanical aptitude and troubleshooting skills, with the ability to diagnose complex hardware and equipment issues.
