ABOUT THIS OPPORTUNITY

You’ll be supporting secure, reliable access to onX Hunt, Offroad, Fish and Backcountry for millions of hunters, anglers and outdoor enthusiasts, including when they’re far from a cell signal.

Job Duties & Functions

• Own the platform. You’ll own onX’s Android identity, subscription, and feature‑access libraries: shared Kotlin modules consumed by every onX Android app. You’ll set their technical direction, decide which patterns to keep and which to replace, and see changes through to production.

• Champion both directions. You’ll represent Android in IAM design work (account management, session management, passkeys, one‑time passwords, entitlements and bundling) and represent IAM in the Android codebase, partnering with backend engineers, Android platform leads and product teams across our apps. You’ll push for new capabilities when the current ones aren’t enough.
• Work with your iOS counterpart. You’ll be partnered on the team with an iOS counterpart to keep identity and entitlement behavior consistent: shared specs, shared test cases, and joint design docs.
• Raise the bar. You’ll grow the team’s client expertise through…
