Important Alert: There is an active job scam using the false domain of careers-onXmaps.com. Please note, onXmaps will never ask for credit card or SSN details during the initial application process. For your digital safety, apply only through our legitimate website at onXmaps.com or directly via our LinkedIn page. For adventurers seeking richer experiences in their pursuits, onX is a pioneer in outdoor navigation offering trusted tools, data, experience, and insight that enables customers to understand landscapes, explore with confidence, increase their odds of success, and better preserve the outdoor experience for all, because onX is built by passionate experts who deeply understand what drives our customers on their own adventures. onX Founder Eric Siegfried was plenty familiar with the challenges of knowing where public and private boundaries could be found. What was unfamiliar was the situation he found himself in during the 2009 season in Southwest Montana—the longtime hunting guide was lost in fading light. Eric managed to find his way back to the truck that night, but the experience lingered as he worked to combine the power of land ownership data and GPS technology to create a tool that told hunters where they could go, where they were, and how to get back home. Eric also recognized that there is no adventure without access, and onX’s DNA drives us to dedicate time, money, and human/vehicle power to clean up trailheads, rebuild trails, and open access to public land. Whether you sit, send, crawl, haul, grip, rip, or slip, onX exists to power your next adventure. Our Values: Solve What Matters Expedition Together Discover New Paths Get After It
