Joshua Kolden
Founder at Avalanche
Los Angeles, California, United States
Summary
👤
SeniorJoshua Kolden is a founder and principal engineer who has driven paradigm shifts at the intersection of media production technology and AI infrastructure for over three decades, from pioneering CG photorealism and early virtual production for Avatar to leading production-scale Kubernetes and agent platforms. He architects production AI agents and multimodal tooling—shipping a model-context protocol server (godoc-mcp, 114+ stars) and pure-Go implementations of OpenTimelineIO and OpenEXR—to replace legacy C++ tooling with container-friendly libraries. Author of SMPTE ST 2114 and the C4 reference suite, he blends standards leadership with hands-on open-source delivery across Go, Python, TypeScript, Swift, and C. At Sphere he built the studio’s container-native microservices platform and a production AI agent that automated code fixes and pull requests ahead of commercial offerings. Relocating to Seattle, he’s seeking principal roles focused on AI infrastructure, agent platforms, or media-scale Kubernetes, with particular interest in AWS/Azure media stacks, NVIDIA Omniverse, and Vision Pro integration.
