Senior Mobile Engineer (Android / iOS, On-Device & SDK)

At our company, we make mobile advertising and discovery experiences more meaningful for users, app publishers, and advertisers - intelligently connecting people across more devices than anyone else in our space. Our on-device footprint, Ignite, ships with hundreds of millions of devices through the world's leading OEMs and carriers, and is the foundation of our strategy to maximize the value of our on-device presence.
As a Senior Mobile Engineer, you'll build and harden the SDKs and on-device services that power app delivery, discovery, and monetization at carrier and OEM scale. This is a high-impact role on a small, autonomous team that owns its products end to end - from design through release, monitoring, and on-call. Your work directly supports our FY27 goals of reducing installation failures, enabling dynamic app delivery, and extending our on-device presence into alternative distribution.
About the Senior Mobile Engineer Role
Design, build, and maintain high-performance Android SDKs and on-device services (with iOS work as our cross-platform footprint grows), focusing on reliability, footprint, battery, and security
Drive down install and delivery failures - improving package-manager reliability, dynamic app-delivery (ASR), and recovery paths across a highly fragmented device and OS landscape
Partner with OEM and carrier integration teams to ship features that operate within tight platform, privacy, and resource constraints
Extend on-device surfaces that power alternative distribution and brand-on-device experiences, a key pillar of DT's FY27 roadmap
Own the full lifecycle of what you build: instrumentation, alerting, rollout strategy, A/B experimentation, and on-call for your services
Raise the bar on code quality through reviews, automated testing, and tooling, and mentor other engineers on mobile best practices.
