Senior Full-Stack Engineer, WeatherXM, GR

About WeatherXM

At WeatherXM, we’re building the world’s fastest-growing, community-powered weather network. with over 9,000 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 top-tier investors like Lightspeed Faction, Placeholder, Consensys Mesh, Protocol Labs, Borderless Capital, Arca, Redbeard, DLAB, SOSV, and angel investors like Juan Benet (Filecoin), having raised a total of a $13 million, we’re combining Web3, IoT, and AI to build a decentralized, global 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.
