ABOUT OnX
We’re a team of builders, adventurers, and risk takers using technology to help people confidently explore the outdoors. Driven by our mission to awaken the adventurer inside everyone, we build products that optimize every outdoor experience and inspire confidence to get out and go further.
We’re a high-growth tech company. The pace is fast, the work takes grit, and ambiguity is part of the job. As the world changes around us, we adapt - continuously evolving how we build, prioritize, and deliver.
Our business moves quickly, and there’s real opportunity to shape what we build next. Each of our verticals - Hunt, Offroad, Backcountry, and Fish - is at a different stage of maturity, which means the challenges you encounter and the impact you have will vary depending on where you sit and what the business needs most.
We operate with an experimentation mindset, continually iterating and improving how we solve problems. We expect our people to use the latest tooling, including AI, thoughtfully and responsibly, pairing human judgment with technology to increase quality, speed, and impact.
Our impact comes to life through the products we build, in the stories of our customers, and in our growing commitment to land stewardship and recreational access.
What You Will Do
onX is seeking a talented Senior Backend Engineer to join our Content Delivery team. In this role, you will build the backend infrastructure that powers offline map experiences for millions of outdoor enthusiasts. You will work on high-performance data pipelines, map tile generation and delivery systems, and large-scale geospatial data processing -- turning terabytes of cartographic data into fast, reliable, offline-capable map content across onX's suite of apps.
We practice data-driven decision making and emphasize experimentation. Engineers on our team have ownership and autonomy to create, develop, and analyze their work in the context of greater company objectives. This is a great opportunity to solve hard problems at the intersection of geospatial technology, large-scale data processing, and outdoor recreation.
This position reports to a Software Engineering Manager III.
TECHNOLOGIES WE USE
Our backend engineers primarily work in Go running in Kubernetes on Google Cloud Platform. The Content Delivery team works extensively with geospatial technologies (PostGIS, vector/raster tile processing, GEOS), GCP data services (Cloud Storage, Dataflow, Cloud Functions, Firebase), and CDN/caching infrastructure for map tile delivery. Experience with large-scale ETL pipelines and offline-first content synchronization patterns is particularly relevant.
