Senior Software Engineer - Map Viewer

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.

The Core Services team builds and maintains onX's proprietary cross-platform map rendering engine, written in C++, shipped as native SDKs to Android, iOS, and web clients. The engine powers map experiences across onX products. We are looking for someone who can bring production engineering expertise — someone who knows what it takes to deliver and operate software at scale, and who is genuinely excited to apply that experience inside a cross-platform mobile graphics engine. The secondary scope of this role is the engine itself. You need to arrive with the CS depth and the production instincts to bring meaningful impact, and a strong motivation to contribute to a successful SDK launch. This role will report to the team's Engineering Manager.
