Job summary

Tilde Bio, Inc. in Cambridge, MA, seeks a Senior Nanofabrication Engineer to advance MEMS-based sensor architectures for our proteomics platform.

You will design, fabricate, and optimize micro- and nanoscale devices, translating concepts into robust processes. The role requires hands-on MEMS fabrication, cleanroom process development, lithography, etching, deposition, and integration with fluidic or biological systems.

Qualifications

• Bachelor's, Master's, or Ph.D. in Electrical Engineering, Materials Science, Mechanical Engineering, Applied Physics, or a related field.
• 5+ years of hands-on MEMS fabrication or micro/nanofabrication experience 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 micro-fabrication 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.

Responsibilities

• Lead the design, fabrication, and optimization of MEMS-based sensor components and micro-scale 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.
