Principal Software Engineer

Company Overview

Red 6 is an innovative Augmented Reality (AR) technology startup leading the way in synthetic air combat training. Our primary technology, supporting our ATARS product, enables pilots to simulate the cognitive challenges of flying while accessing realistic, scalable training in dynamic outdoor environments.

As a Principal Software Engineer at Red 6 you will take a critical role in designing and delivering next‑generation AR pilot training and operating systems. This position is highly hands‑on, driving complex software development. You will identify and implement novel solutions to cutting‑edge augmented reality challenges, working across rendering systems, game engine infrastructure, simulation frameworks, and hardware‑software integration. Your work will integrate state‑of‑the‑art simulation technology with live aircraft and deliver high‑impact capabilities to our military customers.

This is a functional management and developer role with a focus on delivery, technical leadership, and team development. Approximately 25% of your time will be spent performing management duties while the remainder will be focused on active software development.
