C/C++ Unreal Engine Developer (SpacetimeDB)

is the easiest way to build a Multiplayer Game or App

You can write your entire application in a single language (currently C# or Rust) and deploy it as a single binary. No more microservices, no more containers, no more Kubernetes, no more Docker, no more VMs, no more DevOps, no more infrastructure, no more ops, no more servers.
We’re looking for an expert C/C++ Unreal Engine Developer to join the SpacetimeDB team and play a pivotal role in making SpacetimeDB accessible to a whole new group of game developers. You'll be the Unreal Engine subject matter expert who will be charged with delivering this sought after new feature. Your contributions will range from designing, developing, and maintaining our C/C++ and Unreal SDKs to crafting an Unreal Engine integration that feels seamless and robust.

Important Note:

We will be accepting applications until May 11, 2025, before beginning the first round of interviews. If you're interested in the role, we encourage you to watch the keynote and try the demo before applying.

It’s important to us that new team members not only have the right skills, but also share our excitement for how SpacetimeDB is transforming the way multiplayer games and apps are built.

Taking the time to explore the keynote and demo will also make the interview process more productive and meaningful for everyone involved. Thank you for taking the time to consider this opportunity — we’re excited to hear from people who are genuinely excited to be part of what we’re building.

• Any experience with custom build tools or code generation tools are a plus
• Any experience with distributed systems or databases are a plus

We are a fully remote distributed company. We will consider candidates with the above qualifications from anywhere in the world but they MUST be happy to attend meetings during our core collaboration times between 8am and 12pm PST.
Our goal is to provide fair and equitable compensation based on market location as well as an individual candidate’s specific experience level and qualifications for an open role.
