* Duties & Responsibilities:

**### Support Coating Platforms and Processes You support production thin-film deposition platforms and processes. You find root causes in process and hardware issues, track the KPIs that control them, and work with engineers and maintenance to keep the system running efficiently.  ### Fix It on the Floor When yield issues, defects, or excursions appear, you go to the tool first. You contain the issue, find the root cause, and carry corrective and preventive action through 8D/ CAPA methodology until the documentation is closed.  

### Production Support Keeping the site running is the first priority. You are on the floor during critical builds, ramps, and tool recoveries, and you do the work yourself: pulling and analyzing data, preparing trial runs and acceptance plans, coordinating with other teams, and verifying the fix.  ### Complex Machine Ownership Maintenance performs the repairs, and you are accountable for how the tool performs.

You drive tool-level gains in uptime, yield, and cycle time, requalify equipment after maintenance or modification, and hold maintenance, facilities, and outside vendors to completion on repairs and upgrades.  ### Continuous Improvement, Documentation, and New Product Introduction You maintain SPC and trend reporting, run designed experiments, and lead Lean and Six Sigma projects that reduce scrap and increase throughput. You write the work instructions and qualification records that standardize work across shifts, and you train the floor on what changed.

You also help R&D, Product Engineering, and Quality move new coating designs into production.  ### Working Across the Site You collaborate with Design Engineering, R&D, Equipment Engineering, Maintenance, Quality Engineering, Project Management, and Manufacturing, at every level from leadership discussions to task-level execution.

Job Description ###

Required Qualifications
* BS in Physics, Materials Science, or an Engineering discipline. MS preferred.
* 7+ years of manufacturing or process engineering experience in thin-film vacuum deposition (sputtering, e-beam evaporation, ion-assisted deposition, or similar).
* Hands-on ownership of a production coating platform, including its process window, uptime, yield, and cycle time. Running recipes or performing maintenance alone does not meet this bar.
* Proven ability to isolate faults on complex electro-mechanical and vacuum equipment and drive the fix to completion.
* Working knowledge of optical coating process control, including in-situ monitoring and ex-situ metrology, and the ability to trace a spectral result back to a process cause.
* Working knowledge of PFMEA, CAPA, 8D, SPC, and DOE, plus Lean and Six Sigma skills with completed projects that produced measurable gains.
* Track record of hands-on execution and cross-functional work, from leadership…
