C++ Library Developer (video gaming)

Who is mod.io?

mod.io is the world’s most trusted platform for the creation and discovery of fully cross-platform User-Generated Content (UGC) and mods in video games. 



Many of the industries most innovative and successful games have UGC at their core. We’re talking about Counter-Strike, DotA, and PUBG. These games have become house-hold names and that same innovation is what drives us.

 We are a fast-growing, early-stage startup, backed by leading video game venture capital firms including LEGO Ventures, Tencent, and Makers Fund.

Our mission is to connect game studios and publishers with their communities by harnessing the power of UGC. And we’re doing it; our platform is embedded in over 150 games, including some of the biggest and best games in the world. Games like Deep Rock Galactic, Snowrunner, and Dying Light 2, and we support over six-and-a-half-million monthly users.

We are looking for a C++ Library Developer to join our team. This role will work within a project team and is focused on enhancing and supporting our cross-platform SDK that assists game developers with integrating the mod.io service in their game.

Your responsibilities include:

• Manage feedback and communication with partners and other developers to foster a responsive and task-oriented support system.
• Test and implement your design on Linux, Mac, Windows, consoles, VR and mobile to create a cross-platform solution.
• Create a defensive, robust solution that fails gracefully, caches smartly to minimize API calls and provides useful logging to allow developers to debug.
• Keep your house clean, your code will be open sourced on GitHub and must be well documented for our community to fork and adapt as they need.
