Description

  • Own the design, implementation, and evolution of the graphics and rendering stack across Android/Linux and web targets.
  • Write efficient, maintainable, performance-critical C/C++ for system-level and rendering components.
  • Profile and optimize CPU and GPU bottlenecks, shader cost, texture and buffer management, compositor interactions, and end-to-end streaming latency.
  • Investigate and resolve issues across the browser engine, runtime, operating system, kernel, and graphics driver layers.
  • Drive upgrades to underlying platforms such as AOSP versions, browser engines, GLES, and WebGPU while maintaining system stability.
  • Partner with other teams to define and implement testing strategies for rendering correctness, performance regressions, and cross-device fidelity.
  • Scope and execute work independently as a senior contributor within a small, high-trust team.
  • Use AI coding agents and tooling to accelerate research, prototyping, code generation, debugging, and review while verifying outputs carefully.

Requirements

  • Strong systems programming foundation with proficiency in C/C++ for performance-critical, low-level codebases.
  • Deep familiarity with Linux and OS-level internals.
  • Experience with one or more real-time graphics stacks such as OpenGL ES, WebGL, WebGPU, Vulkan, Metal, or DirectX.
  • Experience with shader programming, GPU memory and pipeline optimization, and frame/latency budgeting.
  • Track record of owning complex, multi-component graphics or systems products end-to-end from prototype to production at scale.
  • Daily fluency with AI coding agents and LLM tooling, with a bias toward validating and challenging AI output.
  • Strong written communication skills and a self-directed working style suited to a senior, high-trust team.
  • Depth in browser engine internals such as Chromium/Blink, Gecko, or WebKit, especially graphics, compositor, or rendering subsystems, is preferred.
  • Depth in game engine internals, real-time renderers, or GPU compute frameworks is preferred.
  • Experience with Android internals and custom AOSP development, including kernel, HAL, SurfaceFlinger, system services, GMS, or Android build systems, is preferred.
  • Experience with the Android/Linux graphics stack, including EGL, Gralloc, DRM/KMS, Mesa, or graphics driver work, is preferred.
  • Experience with WebAssembly, WebRTC, and browser security or sandboxing models is preferred.
  • Experience with containers and virtualization such as LXC, namespaces, and cgroups, especially as they relate to hardware-accelerated graphics, is preferred.
  • Experience with real-time network and socket programming, including low-latency streaming protocols and frame pacing, is preferred.
  • Experience with Linux device driver programming is preferred.
  • Experience building, fine-tuning, or evaluating internal AI or agent tooling that supports engineering work is a nice to have.
  • A data-driven mindset that uses qualitative and quantitative signals to guide decisions is a nice to have.
  • Mobile game development experience, including engines, SDKs, and the broader ecosystem, is a nice to have.
  • Background in advanced compression, video codecs, or color management is a nice to have.
  • Graduate work or research experience in computer graphics, systems, or a related area is a nice to have.
