Process Engineer (Etching)

About Syenta
Syenta is pioneering a new era in semiconductor manufacturing with our groundbreaking Localised Electrochemical Manufacturing (LEM) technology. Our manufacturing products build cutting edge advanced packaging for the semiconductor industry by combining patterning and metallization into a single tool. We do that by achieving high-speed, high-resolution metallization at significantly lower costs and energy use, while minimizing emissions and waste.

Founded in Australia, our growing footprint in the US represents a key milestone in our journey. We are building a world-class team where seasoned engineers and ambitious emerging talent collaborate to solve some of the toughest challenges in semiconductor manufacturing.

About The Role
We are seeking a
Process Engineer (Etching)
to join our Tempe team. In this high-impact role, you will develop, fabricate, and characterise critical components for Syenta’s LEM process. You will work hands-on with microfabrication processes while translating experimental data into actionable improvements.

This role is ideal for someone with proven microfabrication experience, particularly in etching of high aspect ratio structures, who thrives in a collaborative, high-growth startup environment and enjoys seeing their work progress from prototype to fully integrated product.

Responsibilities
Process Development & Fabrication

• Follow and refine microfabrication process flows for LEM stamps


• Manufacture prototype LEM stamps to support mechanical, mechatronic, and software systems


• Develop novel MEMS structures compatible with LEM processes


• Develop etching processes for high aspect ratio structures on hard oxides

Cross-Functional Collaboration

• Collaborate closely with Sydney team to develop stamps


• Work closely with materials scientists, chemists, and engineers to integrate microfabrication into the final product


• Transfer developed processes to national and international commercial fabs


• Ensures clear, timely, and well-documented engagement with external suppliers

Characterisation & Quality

• Conduct metrology and inspection to validate process fidelity, yield, and reproducibility


• Translate experimental data into actionable process improvements and report results

Innovation & Continuous Improvement

• Investigate and implement novel etching techniques for high aspect ratio structures


• Stay abreast of emerging microfabrication technologies and recommend enhancements for LEM processes

Requirements

• Bachelor’s degree in Nanotechnology, Electrical Engineering, Mechanical Engineering, Physics, Chemistry, Materials Science, or related field


• Minimum 6 years combined experience in MEMS/microfabrication, academia or industry


• Hands-on experience in metallisation, etching, lithography, thin film deposition, and wafer-to-wafer bonding


• Experience with ICP and CCP plasma etch tools


• Experience with TSVs, TGVs, and high aspect ratio etching structures


• Experience working in semiconductor-grade cleanroom environments

Preferred Qualifications

• Master of Research or Ph.D. with industry experience


• Experience working within commercial semiconductor fabs or local university fabs


• Proficiency with CAD tools (e.g., KLayout) and metrology tools (FIB-SEM, 3D profilometry, optical inspection)


• Experience with lithography (SU-8, AZ resist, EBL resist), wafer/die bonding, and nano-imprint lithography


• Knowledge of copper electroplating and advanced packaging techniques
