Job Summary

About Tilde (FL110)


Tilde Bio Inc. (FL110) is building a next-generation biological sensing platform at the intersection of synthetic biology protein engineering nanopore biophysics electrophysiology signal processing and machine learning. Our goal is to create programmable biological measurement systems capable of extracting rich molecular information from single-molecule interactions.

We believe nanopores generate a high-dimensional measurement of molecular identity and behavior that remains largely untapped. Unlocking that information requires new computational approaches ones that dont yet exist built by people who are comfortable working at the edge of whats known. At Tilde you will work alongside scientists and engineers from diverse disciplines to help define how a new generation of biological sensing systems extract meaning from the physical world.

Tilde is backed by Flagship Pioneering which brings the long-term vision and resources needed to build platforms that dont fit neatly into existing categories.

Position Summary

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 micro-fabrication techniques including lithography etching deposition and thin-film processing. Because our sensors operate at the interface of silicon and biology experience integrating micro-fabricated 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.

Key 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.

Basic Qualifications

  • 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 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.

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.
