About Good Traffic

Good Traffic is revolutionizing outdoor advertising by combining real-world reach with cutting-edge technology. We help brands launch hyper-targeted, high-impact campaigns through mobile outdoor units, powered by advanced geospatial data and real-time analytics.

As we scale our AdTech platform, we’re hiring a Mobile Developer (iOS & Android) to help evolve our native apps used in real-world campaign operations. This is not a greenfield role — our apps are already in production and actively used. We need someone who can quickly understand an existing codebase, improve it safely, and ship high-quality features without disrupting what already works.

What You’ll Do
- Build and ship new mobile features across iOS and Android, aligned with product/design requirements and a shared GraphQL backend.
- Work within existing native codebases and improve them incrementally with a strong focus on maintainability and production stability.
- Improve Android architecture over time (e.g., dependency injection, repository pattern,



reducing coupling, better state handling).
- Continue the migration of Android UI toward Jetpack Compose and support the gradual adoption of SwiftUI on iOS.
- Identify and reduce technical debt while preserving reliability for users in production.
- Write testable code and introduce/expand unit and integration test coverage where it does not yet exist.
- Build and maintain features involving background location tracking, motion/activity signals, camera usage, maps, and push notifications.
- Collaborate with backend engineers to evolve shared GraphQL schema integrations (including open areas such as Payments and Notifications).
- Participate in code reviews, technical discussions, and project standards across both mobile platforms.
- Support release quality through debugging, crash analysis, and performance improvements (Crashlytics, analytics, logs).
