Electrical Engineer

About the Company

We are a venture-backed, stealth-mode technology company building bioelectronic interfaces that read and write signals in living tissue. We are developing hardware and biocompatible materials to interface with biology using optical, electronic, and ultrasound modalities, with the goal of enabling regeneration and repair in the human body.

Our first goal is to demonstrate that we can both read and write two of the most accessible and important organs in the body, with downstream applications in wound healing. Our team comes from leading academic labs and biotech and hardware companies, and we are solving hard problems at the intersection of engineering, regeneration, electrophysiology, and physics. Our goals are measured in months and our progress in weeks, and we are looking for people who are as obsessed as we are.

Position Overview

• You will build the electronics that read and write bioelectric signals in living tissue, starting with PCBs and later moving on to custom ASICs.
• You will own the electronics end to end: schematic, simulation, board bring-up, power management, packaging, and integration with the actuators.
• The devices are low-power and low-voltage.
• Job Responsibilities

You will build the first prototypes on off-the-shelf microcontrollers and existing PCBs, mounted by hand outside the cleanroom.

• When we move to our own chips, you will design mixed-signal ASICs: circuit design, simulation, floorplanning, tapeout, packaging, and testing. Fabrication will be outsourced to a leading foundry.
• You will integrate the electronics with the actuators and package them for use in tissue.
• Cleanroom work (photolithography, nanofab) is mostly for transducers (probes) and integration/packaging. On this work, you will collaborate closely with our actuators and microfab engineers rather than running the full process.
• You will work alongside our ultrasound, materials, optics, and in vivo teams.
• You will set the initial technical direction of the electronics infrastructure and fabrication, and eventually hire new engineers to scale the electronics team.
• The role is on-site and hands-on in the Bay Area. Our team is on site five days a week and frequently works on the weekends. The days can be long as we have a demanding schedule and aggressive milestones to achieve.

Key Qualifications

• You have designed PCBs and integrated microcontrollers yourself, including fabrication and testing.
• You have built low-power, low-voltage systems and owned the power management.
• You have built current and voltage drivers for electrodes, stimulators, ion pumps, or other actuators.
• You have integrated and packaged electronics into a device used outside the lab, ideally implantable or wearable.
• You have shipped a product or a deployed device.
• You have done analog or mixed-signal IC design: circuit design, simulation, layout.

Preferred Qualifications (optional, not required)

• Tapeout experience.
• Cleanroom work.
• Flexible substrates (polyimide, parylene, PEDOT:PSS, IrOx).

What We Offer

• Generous compensation package, salary and equity.
• Medical, dental and vision insurance coverage.
• 401(k) retirement plan, with 3.5% matching.
• Flexible time off and paid holidays.
• Free lunch, plus dinner on late nights.
• Opportunity to work on one of the most important missions of this century.
