Job Description


onX is a pioneer in digital outdoor navigation. With offices in Missoula and Bozeman, Montana, we are inspired by the landscapes that surround us. We bring our outdoor passion to work every day with a singular goal–to awaken the adventurer in everyone. We do this by engineering industry-leading technology, and by crafting dynamic outdoor experiences. 

Through multiple years of growth, we haven’t lost our entrepreneurial ethos at onX. We offer a fast-paced, tech-forward environment where ownership and accountability are essential.


onX is seeking a Software Engineer with a 3D graphics background to help us take our off-pavement mobile GPS experience to the next level. You’ll be our third hire on this new and exciting team focused on a greenfield, cross-platform 3D map viewer. You will work closely with our lead engineer on this project to create a beautiful and efficient 3D map viewing experience for millions of passionate customers. If you’re a linear algebra wiz, love maps, and can wrangle quaternions in your sleep, then this job might be just what you’re looking for!  This person will report to our VP of Research. 


In this position, you’ll work in C++, Kotlin, Swift, and Web Assembly. You will leverage WebGL, OpenGL, and Metal to write a high-performance 3D map viewer. We use a cross-platform graphics library called BGFX to build our viewer for Android, iOS, Windows, Mac, and Web. If you love creating purpose-built, lightweight 3D apps that impact millions of loyal customers, this is the perfect opportunity for you.


Missoula, MT; Bozeman, MT; or Remote from the USA only.  We offer generous relocation assistance to qualified hires interested in relocation to Montana.
