Full-Stack Growth Engineer

ABOUT SHIFTShift pays everyday people to record first-person footage of real-world tasks — repairs, cleaning, cooking, trade work — using a simple phone-mount headset. We're building the dataset that trains the next generation of physical AI systems. We're scaling our B2C operator program and B2B trade partnerships across the US.We move fast. We ship. We figure it out.THE ROLEWe need a builder — someone who's shipped product under real constraints, ideally as a founder or early engineer at a YC-caliber company.
