Principal VR Developer

About the Role

A well-funded startup building an adaptive training platform at the intersection of immersive technology and human performance is looking for its most senior VR engineering hire. The platform integrates real-time physiological sensing to deliver personalized biofeedback experiences that measurably improve focus, emotional regulation, and cognitive performance.

This is a hands-on IC role with high ownership and significant architectural influence. You'll set the technical direction other VR engineers build on, own the full experience stack, and collaborate across neuroscience, hardware, and product. No direct reports.

Note that candidates must be fully on-site in Austin, Texas.

What You'll Own

• End-to-end Unity VR experience architecture on standalone Android hardware — scene composition, interaction systems, state management, runtime performance
• The full graphics pipeline: HLSL/ShaderGraph shaders, render features, post-processing, GPU profiling on-device
• Real-time biosignal data pipelines (EEG, HRV, PPG, eye tracking) driving adaptive, personalized in-experience behavior within strict latency budgets
• Spatial audio pipeline (Steam Audio, Resonance Audio, or equivalent) as a primary modality, not a polish layer
• Backend integrations: REST/WebSocket APIs, cloud infrastructure, analytics pipelines
• Technical direction through architecture reviews, code review, and mentorship

What We're Looking For

• 10+ years shipping immersive VR experiences to real users across multiple platforms
• Deep Unity/C# mastery with a strong portfolio of shipped projects
• Demonstrated graphics pipeline ownership on standalone Android XR hardware
• Experience with biosignal-driven adaptive systems strongly preferred
• Experience in biofeedback, wellness, therapeutic, or performance-focused VR strongly preferred
• Familiarity with the platform/SDK layer underneath Unity strongly preferred
• BS in Computer Science or related field preferred
