About the Role

We are building dexterous hands and fingers for a humanoid, which requires custom electronics at every level—from miniaturized motor drivers to flexible sensor arrays wrapped around fingertips. This role will focus on designing, building, and iterating on hardware to meet the unique spatial constraints, flex requirements, and channel density of a robotic hand with 20+ degrees of freedom.

Off-the-shelf electronics are not designed for these challenges, so most of what we build is custom. You will help close the gap between our advancing mechanical systems and electronics stack by owning real PCB designs, bring-up procedures, and hardware validation work that ships to physical robots.

The robotic hand presents one of the most demanding electronics integration challenges in robotics: small form factor, high channel count, mixed signal, high flex cycle life, and real-time performance. We need electrical engineering talent excited by this challenge, not intimidated by it.

As a small startup moving at speed, interns own subsystems, spin boards, and debug hardware alongside the core team. Every intern is a candidate for a full-time role, as we are building the founding electrical engineering team for a product that will define what humanoid hands can do.

Why You Should Join

  • You are highly technical, regardless of your role, and understand technology deeply.
  • You care about aesthetics and design, striving to create the best product possible.
  • You are self-motivated and get things done without needing external direction.

Requirements

  • Currently pursuing a BS or MS in Electrical Engineering, Computer Engineering, or a closely related field, with solid coursework in circuits, electronics, and systems.
  • Strong grasp of analog circuit fundamentals: Ohm’s law, Kirchhoff’s laws, op-amp configurations, voltage dividers, filter design, and signal conditioning.
  • Understanding of power electronics basics: switching regulators (buck, boost), linear regulators, H-bridge motor drive topologies, and the difference between continuous and discontinuous conduction modes.
  • Foundational knowledge of digital systems: logic levels, pull-up/pull-down resistors, GPIO, SPI/I²C/UART protocols, and microcontroller-peripheral communication at the register level.
  • Hands-on experience with schematic capture and PCB layout in KiCad, Altium Designer, or Eagle—you have designed, ordered, assembled, and powered up at least one board yourself.
  • Understanding of PCB layout best practices for mixed-signal designs: ground plane management, power plane separation, decoupling capacitor placement, trace impedance, and isolating analog/digital domains.
  • Familiarity with rigid-flex or flex PCB design concepts is a strong plus, as robotic fingers have minimal space for rigid boards and connectors.
  • Ability to read component datasheets end-to-end, selecting appropriate ICs (e.g., motor drivers), understanding thermal limits, wiring bootstrap circuitry, and configuring devices over SPI.

You don’t need to check every box to be a great candidate. If you’re excited about building the next generation of robotic hands and believe you’d bring value to the team, we encourage you to apply. A project portfolio or presentation showcasing relevant work will significantly strengthen your candidacy.
