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.

We are seeking a highly motivated MEMS Process Engineer to support both R&D and production activities within our photolithography and RIE process areas. This role is critical to enabling reliable device fabrication as we scale our thin-film and MEMS manufacturing capabilities. The ideal candidate is hands-on, detail-oriented, and experienced in developing robust semiconductor processes while collaborating closely with cross-functional teams.

Role Responsibilities

• Lead process development, optimization, and troubleshooting for photolithography and Reactive Ion Etch (RIE) modules.
• Integrate and qualify new photoresists, polymers, and materials to reliably produce high-resolution patterns for downstream processes.
• Develop, document, and maintain process recipes, work instructions, SPC controls, and experimental reports.
• Characterize lithography and etch processes using metrology tools (profilometry, ellipsometry, microscopy, electrical measurements, etc.) to validate performance and identify sources of variation.
• Partner with equipment engineers to diagnose hardware issues, maintain tool uptime, and ensure stable process capability across production and R&D.
• Program and optimize track coaters, spin profiles, bake temperatures, edge-bead removal (EBR) recipes, and develop process windows for new materials.
• Support cross-functional R&D teams by translating new device designs into robust, manufacturable process flows.

Key Qualifications

• B.S. in Materials Science, Chemical Engineering, Electrical Engineering, Physics, or a related field.
• 3+ years of process development experience in MEMS, semiconductor manufacturing, or advanced materials fabrication.
• Hands-on experience with process characterization tools such as profilometry, ellipsometry, SEM/optical microscopy, film-thickness measurement, and critical-dimension analysis.

Preferred Qualifications

• Demonstrated ability to develop, tune, and optimize RIE recipes, including plasma parameter adjustments and etch-rate/anisotropy characterization.
• Experience conducting short-loop experiments and refining lithography processes (coat, bake, expose, PEB, develop).
• Working knowledge of ISO 9001 or similar quality-management systems.
• Experience with layout or mask-design software such as KLayout, AutoCAD, Cadence, or similar tools.

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)
