Join us in pioneering life-changing technology

The Role
We’re hiring a Biointerface Engineer (Neural Interfaces / Tissue Engineering / Cell Engineering) to own the design and development of the biological interface layer of our neural systems. This role is responsible for the electrode–tissue interface as a complete system, spanning cells, materials, and integration with hardware. You will define how our devices interface with the body, from in vitro systems through in vivo validation. This is not a narrow cell engineering role. It sits at the intersection of tissue engineering, neural interfaces, and device integration.You will be working closely with our multi-disciplinary team of electrical engineers, materials scientists, neuroengineers, and operators in our Palo Alto lab.

‍What You’ll Do
- Own the design of the biointerface layer, including cells, scaffolds, and material systems that connect device to tissue
- Develop and optimize cell strategies including: primary cell culture, stem-cell-derived systems
- Optimize cell strategies with long-term clinical and regulatory pathways 
- Design and evaluate cell–material interfaces (e.g., hydrogels, ECM coatings etc) to improve integration, stability, and signal quality
- Build and run in vitro interface models to characterize coupling between biology and electronics
- Partner closely with electrical and device teams to optimize signal quality, impedance, and interface performance
- Work with in vivo teams to translate in vitro systems into implantable, testable constructs
- Define and document protocols for reproducible cell culture, interface fabrication, and experimental workflows
- Drive iterative development across the loop: interface design → implantation → signal → failure mode → redesign
‍
What We’re Looking For
- Experience with cell engineering or genetic manipulation techniques (e.g., CRISPR, viral transduction) where relevant
- Strong hands-on experience in mammalian cell culture (primary cells, stem cells. or differentiated systems)
- Strong background in tissue engineering, bioengineering, neuroscience, or related disciplines
- Experience with in vitro electrophysiology techniques or electrically active cell systems
- Experience in developing and optimising cell–material interfaces (e.g., hydrogels, ECM, coatings)
- Experience designing and running in vitro assays to evaluate biological–electrical interface performance
- Ability to lead projects independently while working in a highly collaborative environment
- Strong communicator with ability to document protocols and drive reproducible experimental workflows
- PhD in Bioengineering, Molecular Biology, Neuroscience, or a related field or equivalent industry experience
- Ability to think at the system level across biology, materials, and device integration

‍Nice to Have
- Familiarity with microfluidics, hydrogel substrates, or implantable systems
- Experience with translational cell therapies
- Animal handling and surgery experience 
- Familiar with in vivo electrophysiology 
- Experience integrating biological systems with devices or materials
- Previous work with startup or interdisciplinary R&D environments
- Understanding of regulatory-minded workflows (GLP, FDA-facing studies)
- Basic data analysis skills (Python, MATLAB, ImageJ, etc.)
- Experience working across in vitro to in vivo translation

Salary/Pay Range
Competitive salary + equity + benefits. Individual pay is determined by several factors, including job-related skills, experience, and relevant education or training.

Benefits
- Competitive salary and equity
- Medical, dental and vision
- Flexible vacation and company-paid holidays
- Healthy meals and snacks provided for non-remote employees
