Our mission is to continuously drive the scale of genomic information to enable unprecedented advances in biology and improvements in human health. We have developed a foundational new approach to sequencing at scale that overcomes limitations due to the high costs of current technologies. We are well-funded and have raised approximately $600 million from global top-tier investors. Our team brings together unique and diverse expertise across multiple disciplines from healthcare and life sciences to engineering to technology and software and beyond. We are a collaborative group including successful entrepreneurs chemists hardware and software engineers genomics and biotechnology experts molecular and computational biologists software and algorithm experts and operations and commercial leaders. Join us to develop and commercialize technologies that unleash the power of genomics at scale and empower the future of human health.

We are looking for a highly motivatedSenior Scientist Surface Chemistry to join our team!

As a Senior Scientist Surface Chemistry you will lead R&D and process development for surface-modified substrates. You will design surface chemistries build metrology-to-performance correlations and deliver robust scalable processes with clear standard operating procedures (SOPs).

This is a full-time onsite position at our Fremont CA location.

How Youll Contribute

  • Develop and scale surface functionalization processes; link chemistry and process settings to assay and product performance
  • Design and optimize surface chemistries including organosilanes thiols/SAMs linkers passivation and blocking strategies and biomolecule immobilization
  • Run Design of Experiments (DOE) driven optimization and define robust operating windows and control plans
  • Build Quality Control (QC) workflows including metrology panels acceptance criteria and correlation models between metrology and functional performance
  • Own troubleshooting and failure analysis; drive corrective actions via process controls and SOP updates
  • Drive innovation by prototyping next-gen coatings and chemistries assessing feasibility and risk and recommending paths forward
  • Partner cross-functionally with chemistry biology and engineering teams and mentor technicians and junior staff
  • Other job duties as assigned

Qualifications Skills Knowledge & Abilities

  • Degree in chemistry chemical engineering materials science and engineering physics or related field
  • BS with 8 years MS with 5 years or PhD with 3 years of related industry experience. PhD is preferred
