Who we are 

TFG is the largest mobile game company in Latin America, and one of the largest in the world. In 8 years, we have released over 70 games, including hits such as Sniper 3D, the leading FPS game on App Store and Google Play Store, and Colorfy, the world's most popular coloring app. Our games have been downloaded 1 billion times in 125 countries. The team started with two brothers, and now there are around 320 of us – and counting. To build the very best mobile games, we gather exceptional talent in software engineering, art and animation, product design and management, marketing, and data science.

About the Team

Backend Engineers are responsible for defining the architecture and implementing systems with high availability and scalability which interact with millions of players across the world and are essential to our games. Besides directly impacting our players, our team is also responsible for developing internal systems and tools, used by a wide variety of teams of the company, from other engineers to recruiters. To achieve both goals, we work with a broad technology stack and have a mindset of being fully responsible for our systems, from their conception to incident resolution and troubleshooting in production. We are always collaborating with other engineering teams, to provide the best experience to our players.We own several services that, combined, serve more than 1 million requests per minute. We know this number will only grow and we're looking for engineers that can help with the challenges of developing backend systems that perform well at large scale.
