Senior Nanoscientist

About SubsenseSubsense is a deep-tech company developing the world’s first non-surgical, bidirectional brain-computer interface powered by plasmonic and magnetoelectric nanoparticles. Our mission is to unlock direct communication between the human brain and AI - starting with medical applications such as stroke recovery and moving toward cognitive enhancement for healthy users. Headquartered in Palo Alto, Subsense brings together leading scientists and engineers to redefine the future of human–machine interaction.
The Opportunity
We're looking for a Senior Nanoscientist to take ownership of nanoparticle design and development for our BCI platform. This role is for someone who has already built a track record in nanoscience research and is ready to lead projects independently, mentor junior scientists, and make the technical calls that shape how our nanoparticles are designed, made, and scaled. You'll work closely with the Nanoscience team and Acting Director, R&D Execution across neuroscience, hardware, software, and data science teams to advance our technology.

Key Responsibilities

Lead the design and development of new nanoparticle technology, including synthesis, functionalization, and formulation strategies
Set and maintain standardized characterization methods for the company, ensuring design criteria are consistently met
Drive scale up of nanoparticle synthesis, working directly with contractors and collaborators to move from lab to production scale
Mentor and provide technical guidance to junior nanoscientists on the team
Partner with academic and industrial collaborators to advance the company's nanoparticle IP and research agenda
Work across hardware, software, data science, and regulatory teams to integrate nanoscience advances into BCI technology
Help operate and maintain internal nanoscience laboratories, with input on lab planning and equipment decisions
Represent Subsense's scientific work through peer reviewed publication and conference presentations

What You'll Bring

A PhD in chemistry, materials science, or a similar field, with 5 to 10 years of industrial or postdoctoral research experience
Deep expertise in inorganic and organic nanoparticle synthesis, modification, and characterization, with a track record of leading projects independently
Strong understanding of biological applications of nanoparticles
