Senior Hardware Engineer, Nanofabrication and MEMS Development

Flagship Pioneering, Inc.•Cambridge, MA

6d•$108,000 - $176,000•Onsite

About The Position

We are seeking a highly skilled and innovative Senior Nanofabrication Engineer to drive the development of MEMS-based sensor architectures and micro/nanoscale structures that are core to our next-generation proteomics platform. This individual will play a critical role in designing, fabricating, and optimizing micro- and nanoscale devices, translating novel concepts into robust, manufacturable processes. The ideal candidate has deep hands-on experience in MEMS fabrication, cleanroom process development, and microfabrication techniques including lithography, etching, deposition, and thin-film processing. Because our sensors operate at the interface of silicon and biology, experience integrating microfabricated devices with fluidic, chemical, or biological systems is highly valued. This role requires close collaboration with electrical, mechanical, materials, and bioengineering teams to ensure seamless integration of MEMS sensors into larger instrument systems. This is an on-site position requiring regular cleanroom and lab work.

Requirements

B.S., M.S., or Ph.D. in Electrical Engineering, Materials Science, Mechanical Engineering, Applied Physics, or a related field.
5+ years of hands-on experience in MEMS fabrication or micro/nanofabrication in industry or advanced research environments.
Demonstrated expertise in cleanroom processes including photolithography, thin-film deposition, and etching techniques (RIE/DRIE preferred).
Experience designing microstructures and mask layouts using CAD tools (e.g., L-Edit, KLayout, or similar).
Strong understanding of MEMS device physics and materials selection.
Experience with wafer-level processing and packaging considerations.
Hands-on experience with microfabrication characterization and metrology tools.
Strong problem-solving skills and the ability to iterate quickly in a fast-paced R&D environment.
Excellent written and verbal communication skills.

Nice To Haves

Experience developing MEMS-based sensing devices (mechanical, optical, electrical, or fluidic).
Familiarity with microfluidics or bio-integrated MEMS devices.
Experience with wafer bonding, surface functionalization, or nanostructure fabrication.
Prior experience working with external semiconductor foundries.
Experience in early-stage or startup environments.

Responsibilities

Lead the design, fabrication, and optimization of MEMS-based sensor components and microscale structures, from concept through manufacturable process.
Develop and optimize cleanroom process flows including photolithography, thin-film deposition (PVD/CVD/ALD), dry and wet etching, and wafer bonding.
Design masks and layouts, and characterize micro- and nanoscale structures using metrology tools such as SEM, profilometry, ellipsometry, and optical microscopy.
Perform failure analysis and root-cause investigations to improve yield and device performance.
Collaborate with electrical, systems, and bioengineering teams to integrate MEMS sensors with PCB, packaging, and fluidic/bio-interface solutions.
Support process transfer to external foundries or manufacturing partners, and maintain thorough documentation of processes, results, and design revisions.
Contribute to intellectual property development and technical strategy, and stay current with advancements in MEMS fabrication, materials science, and nanoscale device engineering.
