Aghanim is an integrated commerce, liveops automation, community engagement, and payments platform for video games.
Mobile games have traditionally depended on app stores for distribution, payments, and player relationships. We believe there is a better way. Aghanim helps game studios build direct relationships with players, sell directly, and build their future on their own terms. Today, more than 100 games worldwide are already building this future with Aghanim.
Our team brings together people across Los Angeles, New York, Seoul, Beijing, London, Lisbon, Belgrade and other locations around the globe, with deep expertise in gaming, fintech and technology. We move quickly, keep communication direct, and focus on getting things done. We believe the best people thrive when they have autonomy, ownership, and a stake in the company's success.
We're looking for a Senior Python Developer to join the Platform team and take ownership of core backend systems powering Aghanim — a direct-to-consumer (DTC) platform that helps mobile game developers monetize outside app stores. We act as a Merchant of Record, handling payments, compliance, and taxation across 200+ territories, while providing game studios with tools for LiveOps automation, player segmentation, and community engagement.
The codebase follows domain-driven design with 60+ business domains, strict code quality standards, and AI-assisted development as a standard part of the workflow. You'll work across a modern Python stack — Python 3.13+, FastAPI, Pydantic — with a heavy integration layer connecting game backends, and external services.
