AppsFlyer builds technology at massive scale, powering measurement, analytics, and fraud prevention across billions of mobile events every day.
Join AppsFlyer’s Core SDK Team, responsible for building and maintaining the core mobile technology that powers AppsFlyer’s platform across millions of applications worldwide. The team develops high-performance, reliable, and secure SDK components used by developers globally.
The Core SDK team operates across Android and iOS platforms, with a long-term vision of a unified mobile SDK engineering team. Engineers collaborate across platform boundaries while maintaining deep expertise in their primary mobile ecosystem.
Operating at the intersection of mobile platforms and large-scale distributed systems, the team tackles complex challenges such as performance optimization, platform compatibility across thousands of devices, and maintaining highly reliable code that runs on billions of devices.
As the team evolves, we are also expanding beyond traditional mobile development and scaling engineering capabilities with AI. This includes building and using AI-powered tooling, MCP-based systems, and agent-driven automation to improve developer productivity, testing, and SDK innovation.
Engineers in the team therefore have the opportunity to work not only on mobile platform challenges, but also on emerging areas where mobile infrastructure, AI systems, and developer platforms intersect.
