For the Slang-curious: I'll be doing a virtual meetup to teach the very basics of getting started with Slang -- all the way up through drawing your first (2D) Gaussian splat! Join me on May 20, at 8am Pacific / 11am Eastern / 4pm British Summer / 5pm Central European:

Getting Started with Slang: Draw Your First Splat

A few weeks ago, I posted a blog walking through a very simple example of how you can use Slang's autodiff to make a set of gaussian splats learn an image -- yesterday, I finally posted the follow-up article that shows how you can speed things up to achieve much better image quality in much less time: https://shader-slang.org/blog/2025/04/30/neural-graphics-first-principles-performance/
Neural Graphics: From First Principles to Performance

I got a comment at Vulkanised that really resonated, asking how folks from traditional triangle-mesh-land can approach neural graphics. Because it was also new to me really recently, I thought I should take a crack at writing a welcoming introduction for beginners. Here's the result:

Slang is now officially under open governance at Khronos, and what better way to celebrate than running Slang shaders directly in your browser with WebGPU?

You can also compile your shaders to a variety of targets including Metal and HLSL. I'm giddy to finally share this!

Slang Playground

Interactive playground for experimenting with Slang shading language. Write, compile, and visualize shader code in real-time.

Anyone going to #SIGGRAPHAsia2024 ? Catch me at the BOFs for Vulkan & Slang. (Also tell me your favorite food spots in Tokyo.)
Senior Graphics Compiler Engineer, Slang

Computer Graphics is undergoing a significant transformation spurred by the AI revolution. Slang, an open-source language and compiler for portable real-time graphics programming, is at the forefront of this transformation. We enable developers to leverage AI-driven, neural techniques in graphics workloads to create realistic and immersive experiences. Does this sound exciting to you? If so, the Slang team may be just the place! We are looking for an experienced Senior Engineer with extensive end-to-end experience in designing programming languages and graphics systems. In this role, you will have a direct impact on ongoing critical projects at NVIDIA and beyond, and play a crucial role in shaping the future of computer graphics. What You’ll Be Doing: Invent the future of programming models for real-time graphics developers within an open-source shader compiler framework. Collaborate with top-tier graphics engineers and neural graphics researchers to evolve and improve the language and compiler implementation. Introduce new language constructs, implement critical optimizations, and add language support for GPU hardware capabilities. Establish and drive product-critical performance and quality metrics. Profile, debug, and optimize the Slang stack for both compile-time and run-time performance. Coordinate with a distributed development team on a large code base using modern software development processes, including continuous integration, testing, and deployment. What We Want to See: M.S. or Ph.D. in computer science or equivalent experience. 10+ years of experience in software development. Proficiency in C++ and HLSL/GLSL. Excellent software engineering fundamentals (source control, CI/CD, testing/validation, packaging, release). Proven track record developing, testing and releasing production-grade, complex software. Extensive experience in developing and optimizing real-time rendering systems and/or parallel programming models. Deep knowledge of compiler implementation techniques, including parsing, semantic checking, intermediate representations, and optimization. Strong Collaboration skills to work with researchers, application developers, graphics drivers, and tools teams. Familiarity with modern Graphics APIs such as Direct3D 12, Vulkan, and/or OptiX. Ways to Stand Out from the Crowd: Understanding of modern techniques in Machine Learning, Deep Neural Networks, and Generative AI, with relevant contributions to major open-source projects. Proficiency in general-purpose languages such as Rust or Swift. Experience in programming language design and implementation or type theory. Proven track record in large-scale real-time graphics application development. With competitive salaries and a generous benefits package, we are widely considered to be one of the technology world’s most desirable employers! We have some of the most forward-thinking and hardworking people in the world working for us and, due to unprecedented growth, our teams are rapidly growing. The base salary range is 180,000 USD - 339,250 USD. Your base salary will be determined based on your location, experience, and the pay of employees in similar positions. You will also be eligible for equity and benefits. NVIDIA accepts applications on an ongoing basis. NVIDIA is committed to fostering a diverse work environment and proud to be an equal opportunity employer. As we highly value diversity in our current and future employees, we do not discriminate (including in our hiring and promotion practices) on the basis of race, religion, color, national origin, gender, gender expression, sexual orientation, age, marital status, veteran status, disability status or any other characteristic protected by law. NVIDIA is the world leader in accelerated computing. NVIDIA pioneered accelerated computing to tackle challenges no one else can solve. Our work in AI and digital twins is transforming the world's largest industries and profoundly impacting society. Learn more about NVIDIA.

I won't be at SIGGRAPH this year, but people who will should check out Hai Nguyen's talk on using Slang in Vulkan, at the Vulkan BOF on Wednesday July 31. We've been up to some cool stuff!
My wife @ShannonIn3D and I have decided to renew our vows.
