Lead Mobile Engineer

About Drover Drover is replacing fencing on ranches with an ear tag that moves cattle using their muscles. Virtual fencing is already becoming one of the biggest shifts in livestock management, with multi-billion-dollar valuations. But those systems are all collar-based, infrastructure-heavy, and built around electric shock training. Drover is taking a fundamentally different approach: shrinking virtual fencing into an ear tag, the form factor every rancher already knows. We're building a rugged, solar-powered hardware product that combines low-power GPS, cellular, and satellite connectivity, embedded sensing, and patent-pending muscle stimulation to guide cattle directionally, replacing the need for electric shock. Drover was founded by Callum Taylor (Harvard EE), who comes from 5 generations of ranching, and Samuel Aubin (USYD, CS), both of whom grew up in Australian ranching towns and have an intricate understanding of the problem space. We’re backed by Workshop Ventures (the founders of SimpliSafe) and have recently closed an oversubscribed seed round. We’ve also signed with a top-tier contract manufacturer and will launch commercially in Q1 2027. About the role As the Lead Mobile Developer, you'll own and scale the React Native application that serves as the main touchpoint for ranchers to move and monitor their cattle. This is a high-impact role at the intersection of geospatial data, livestock operations, and connected hardware. Performance and reliability here directly affect the animals, land, and livelihoods of our customers. We're an early-stage startup. You'll have high ownership in what you build and a real hand in where the product goes. You'll own our mapbox-powered maps, the user experience, and the data flows that keep everything in sync with our backend. Over time, you'll grow and lead a mobile team.
