Join a project where your work directly impacts large-scale mobile monetization platforms used by publishers worldwide. We are looking for a Senior Android Developer with strong expertise in native Android SDK development and production-grade mobile engineering.
You will work remotely with a distributed team on maintaining and enhancing open-source Android SDKs integrated into real mobile applications at scale. This role is ideal for engineers who enjoy solving complex architectural and release-quality challenges beyond standard application development.
We at Sigma Software offer the opportunity to work with modern technologies, collaborate with experienced professionals, and contribute to high-performance SDK solutions in the growing AdTech domain.
CUSTOMER
Our Customer operates in the mobile advertising technology industry and develops SDK solutions that help mobile publishers monetize their applications through in-app advertising infrastructure. Their products support ad delivery, rendering, analytics, and communication with advertising platforms while serving performance-sensitive production environments.
PROJECT
The project focuses on the ongoing development and maintenance of native Android advertising SDKs distributed through Maven and integrated into third-party mobile applications. The SDKs support banner and video advertising, SSP communication, beacon and pixel tracking, timeout handling, and publisher-side integration processes.
The team works in a release-critical environment where stability, backward compatibility, and SDK reliability are essential. This is an opportunity to contribute to scalable open-source SDK solutions already used in production rather than building a product from scratch.
