MEMS Process Engineer

Science is a clinical stage, vertically integrated technology company focused on solving some of neuroscience’s hardest questions and most serious unmet medical needs. We work to restore quality of life to those with debilitating conditions for which there are no treatment options, creating devices aimed at restoring vision, cognition, and mobility to patients who have lost it. To support progress across our industry, we provide state-of-the-art components and vertically integrated infrastructure for others to build on via Science Foundry. The Senior Process Engineer owns the end-to-end fabrication lifecycle for semiconductor and MEMS devices, from initial specification through product delivery. This role requires deep cleanroom expertise in CMOS post-processing, independent technical leadership, and the ability to manage cross-functional project teams and external vendor relationships. Role Responsibilities Project Ownership: Drive post-processing development from specification to final delivery, working autonomously or leading dedicated project teams Vendor Management: Identify outsourcing opportunities, prepare technical statements of work, oversee vendor execution, and integrate external deliverables within specification, schedule, and budget constraints Recipe Development: Design, baseline, and optimize thin-film deposition, lithography, and thermal processing using Design of Experiments (DOE) methodologies Mask Design: Create photolithographic mask layouts and generate GDSII/OASIS files using tools such as KLayout or L-Edit Etching Processes: Execute and optimize reactive ion etching (RIE), deep reactive ion etching (DRIE), and wet chemical etches (isotropic/anisotropic) Wafer Bonding: Perform temporary and permanent wafer bonding, thermal/chemical debonding, and sacrificial layer release processes Backend Operations: Execute wafer dicing (saw/laser), manage kerf clearance and chipping specifications, and oversee die preparation and substrate cleaning Advanced Metrology: Conduct failure analysis and material characterization using SEM, FIB, EDS, and ToF-SIMS Root Cause Analysis: Interpret process data and metrology results to diagnose defects and implement corrective actions Process Control: Apply Statistical Process Control (SPC) methodologies to maintain process stability Enforce cleanroom protocols and contamination control standards Manage hazardous materials (including HF and solvents) per safety regulations Maintain detailed process documentation and equipment logs Key Qualifications B.S., M.S., or Ph.D. in Electrical Engineering, Materials Science, Physics, or related engineering discipline 7+ years hands-on experience in Class 100/1000 cleanroom environments 2+ years in a technical leadership or project lead capacity Demonstrated experience with CMOS device post-processing Preferred Qualifications Proficient operation of cleanroom equipment: lithography systems, PVD/CVD tools, dry/wet etch stations, wafer bonding tools, dicing equipment Expert-level knowledge of semiconductor process integration Hands-on experience with SEM and advanced analytical instrumentation Working knowledge of Statistical Process Control and DOE methodologies Proficiency with mask layout software (KLayout, L-Edit, or similar) Excellent project management and vendor coordination skills Effective communication across technical and non-technical audiences Self-motivated with ability to work independently and collaboratively Benefits: At Science, our benefits are in place to support the whole you: Competitive salary and equity Medical, dental, vision and life insurance Flexible vacation and company-paid holidays Healthy meals and snacks provided for non-remote employees Paid parental, jury duty, bereavement, family care and medical leave Dependent Care Flexible Spending Account, subsidized by Science Flexible Spending Account 401(k) Science Corporation is an equal opportunity employer.
