Principal Inkjet Process & Integration Engineer

Genscript Biotech Corp•Redmond, WA

78d•$110,000 - $160,000

About The Position

Lead the development of a high-precision DNA oligo synthesizer by integrating inkjet printing, microfluidics, and motion control systems. Own the optimization of jetting parameters for custom substrates and prototype microfluidic washing chambers to maximize fluid exchange efficiency. Partner with overseas manufacturers to design, validate, and deploy R&D instruments, ensuring robust performance through hundreds of cycles.

Requirements

Bachelor's or Master's degree in Chemical Engineering, Mechanical Engineering, Materials Science & Engineering, or a related field, with 5+ years of hands-on experience in inkjet printing or precision fluid jetting technologies.
OR
PhD in a relevant engineering or physical science discipline with 3+ years of applied R&D experience in jetting systems or microfluidic instrumentation.
Direct experience tuning printhead jetting parameters (waveforms, drop volume, frequency, satellite droplet control) on customized substrates.
Exposure to inkjet driver electronics, reagent delivery architectures (pumps, valves, pressure regulation), and/or fluid path design.
Familiarity with integrating jetting systems into custom instrumentation - especially involving motion control and sealed fluidic chamber.
Fluent in Chinese (required) for vendor coordination.

Nice To Haves

Hands-on prototyping of microfluidic components or washing chambers.
Experience transferring lab-scale jetting processes to integrated, automated platforms.
Prior collaboration with overseas hardware vendors or contract manufacturers.
Proficiency in CAD (e.g., SolidWorks) and fluid dynamics simulation (preferred).
Familiarity with LabVIEW or Python for instrument control (bonus).

Responsibilities

Technical Ownership: Serve as primary engineer for inkjet process development and microfluidic chamber prototyping.
Cross-Functional Collaboration: Work with chemists, facilities, and EHS to ensure utility support (gas, exhaust, waste) for instrument operation.
Vendor Management: Direct overseas partners in design, cost estimation, and validation (DFM, FMEA, DOE).
Problem Solving: Deploy SPC, DOE, and root-cause analysis to resolve jetting instability or fluidic inefficiencies.
Technology Integration: Adapt cutting-edge materials (e.g., hydrophobic coatings) and components (solenoids, pumps) into designs.
