Performance Oriented, Sr. C++ Engineer - Rendering

About Rive

Rive is where designers, animators, and developers build interactive experiences. Design, animate, and code in one place. What you build in the editor is what ships in your app, game, or website. No mockups, no prototypes, no handoff. The real thing.

Companies like Spotify, Duolingo, LinkedIn, Google, and Fortune 500 automakers use our open-source runtimes to build once and ship everywhere — websites, apps, games, and vehicles. With Rive, designers and developers work with the same tools. No silos. What you see in the editor is what ships in production.

Our Rendering team is looking for a very experienced C++ Engineer, with an obsession for making code FAST, to work on our core animation runtime. You will be part of a small, low-level, performance oriented team that specializes in GPU programming, GLSL and C++. Developing and maintaining the core Rive C++ runtime with a focus on performant rendering on all platforms. The core runtime is what drives our novel state machine and generates the Bezier curves that we render.

Some of what you’ll do:

• Own, architect, and implement Rive’s C++ core animation runtime.
• Work closely with world class designers to innovate and implement brand new features.
• Focus on improving performance from C++ optimizations, to SIMD, to threading, to clever math formulas, you’ll be continually thinking about how to maximize performance.
• Contribute to and create new automated CI workflows on GitHub to ensure the quality of our runtime across all architectures and platforms.

What you will bring:

• 5+ years of professional experience programming in C++.

• Proven ability to come up to speed and contribute quickly to a complex code base.
• Self-directed with prior experience owning and delivering features.

• Passion for math, with strong skills in areas relating to Bezier curves, including linear algebra and calculus.
• Experience writing numerically stable routines for 32-bit floating point processors.
• Experience working with vector instructions sets (AVX, SSE, NEON, Web Assembly SIMD)
• Proficiency in dev tooling and automation (GitHub CI, etc.)

Bonus points for:

• Experience in WASM
• Prior experience working in a startup or small, nimble environment
