Founding Sensor Engineer — PlainHand

Founding Sensor Engineer — PlainHandWe're building the sensing layer for dexterous robotics: high-fidelity capture of human motor intent, translated across platforms. Three provisional patents filed. An active fingertip force sensor programme that needs someone to own the physics end to end.What you'd ownThe transducer itself. Capacitive and piezoresistive sensing elements, from first principles through to a part that measures repeatably on a bench. Diaphragm mechanics, error budgets, noise floor, drift, hysteresis. The question of whether a design can hit its spec before anyone spends money machining it.Right now that means a fingertip force sensor with real open questions: what the low end actually resolves, how a compliant contact surface affects the calibration chain, and where the repeatability limits sit under off-axis loading. Real problems, not busywork.What we're looking forYou've designed a sensing element from scratch, not just integrated someone else'sCapacitive or piezoresistive transducer experience, MEMS background welcomeYou do the maths first and treat the render as a hypothesisComfortable on the bench: load cells, calibration rigs, cycling dataYou'll tell me when a design doesn't workWhat this isCo-founder title. Equity-based only. No salary at this stage — this is early, and I'd rather be straight about that than dress it up. You'd be joining a small group of people who own real pieces of this.What this isn'tA firmware role. A general mechanical engineering role. A job where the spec arrives finished, and you build to it.If you've built a sensing element from the ground up and want to do it again on something that matters, message me directly.— Levi Ezagui, Founder, PlainHand
