Senior Full-Stack Engineer

About WeatherXM

At WeatherXM, we’re building the world’s fastest-growing, community-powered weather network. with over 8,000 stations deployed across 80+ countries (and growing fast), we’re tackling the global gap in hyperlocal weather data by rewarding individuals who install and maintain stations with our native $WXM token. Our network already powers a product that delivers real-time, hyperlocal forecasts—and we’re now focused on expanding into new markets and unlocking even more impactful use cases through our unique, community-driven approach.

Backed by a $13 million raise from top-tier investors like Lightspeed Faction, Placeholder, Consensys Mesh, Protocol Labs, Borderless Capital, Arca, Redbeard, DLAB, SOSV, and angel investors like Juan Benet (Filecoin), we’re combining Web3, IoT, and machine learning to build a decentralized, trusted weather infrastructure—especially where it’s needed most.

If working on meaningful tech with real-world impact sounds exciting to you, we’d love to hear from you. We’re just getting started.
