Senior Scientist, Surface Chemistry

We are looking for a highly motivated Senior 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 You’ll 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
• Hands on experience supporting a commercial product where surface chemistry is a key component
• Strong surface chemistry and surface characterization skills with ability to correlate measurements to function
• Hands-on metrology experience, including AFM, Ellipsometry, XPS, FTIR, SEM, fluorescence microscopy; additional techniques are a plus
• Proven SOP authoring and release and documentation discipline in a product development environment
• Demonstrated project leadership in framing, planning/DOE, execution, analysis, and excellent communication skills
• Experience with vapor-phase and CVD-style deposition of organosilanes, thiols, or related surface chemistries, biomaterials coatings and/or bioconjugation chemistry
• Familiarity with microfabrication context such as PVD/CVD/PECVD/ALD, lithography, etch, wet bench/cleaning
• Data and image analysis (Python, FIJI, JMP, Matlab/Octave, R)
• Experience using Statistical Process Control (SPC) to monitor process stability and variation
