XR Software Engineer

Job Description

This Job description is an overview of the duties and responsibilities of the XR Software Engineer. It does not imply that these are the only duties you will perform in this position. You should expect to take on tasks outside the scope of this role in support of the mission of the National Security Space Institute (NSSI).

Sigmatech is seeking a creative and motivated XR Software Engineer to join our growing Technical Solutions Group (TSG). In this role, you'll help design and develop interactive, immersive training systems that support the National Security Space Institute (NSSI) Digital Learning Team (DLT) in Colorado Springs, CO
, as well as other defense-focused educational initiatives.
This is an in-person 6-month contract role and is not eligible for remote work. You'll collaborate closely with an experienced senior XR engineer, multimedia developers, 3D artists, and subject matter experts to deliver compelling real-time 3D experiences across multiple platforms—including desktop, XR headsets, WebGL, and mobile devices. This role is a 6-month contract position primarily to focus on transferring our Unity applications to Unreal for a switch in game engines.

However, you may be tasked with helping on other projects outside of the transfer.
