About the role

Key responsibilities & impact

Own the design, implementation, and evolution of our graphics and rendering stack across native (Android/Linux) and web (WebGL, WebGPU) targets.
Write efficient, maintainable, performance-critical C/C++ for system-level and rendering components, with hard requirements on frame budgets, memory, and latency.
Profile and tune the full pipeline: CPU/GPU bottlenecks, shader cost, texture and buffer management, compositor interactions, and end-to-end streaming latency.
Investigate and resolve faults in complex environments, tracing issues from the browser engine down through the runtime to the OS, kernel, and graphics driver.
Drive upgrades to the underlying platforms (AOSP versions, browser engines, GLES/WebGPU evolution) while keeping the system stable and shippable.
Partner with other teams to define and implement robust testing strategies for rendering correctness, performance regressions, and cross-device fidelity.
Operate as a senior independent contributor: scope your own work, drive it to completion, and communicate clearly with a small, high-trust team.
Work natively with AI coding agents and tooling (Claude Code, Cursor, agentic workflows, custom internal agents) to accelerate research, prototyping, code generation, debugging, and review, treating these tools as a junior pair you direct and verify, not a passenger.

Requirements

What you’ll need

Strong systems programming foundation: C/C++ proficiency on performance-critical, low-level codebases, with deep familiarity with Linux and OS-level internals.
Deep experience with one or more real-time graphics stacks: OpenGL ES, WebGL, WebGPU, Vulkan, Metal, or DirectX, including 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 research prototype through production at scale.
Daily fluency with AI coding agents and LLM tooling, with a clear bias toward verifying and pushing back on AI output rather than accepting it.
A "dig until it bleeds" investigative instinct: the drive to understand every layer of the system.
Strong written communication and a self-directed working style suited to a small, senior, high-trust team.
We'd love to see depth in two or more of the following:
Browser engine internals (Chromium/Blink, Gecko, WebKit), particularly the graphics, compositor, or rendering subsystems.
Game engine internals, real-time renderers, or GPU compute frameworks.
Android internals and custom AOSP development (kernel, HAL, SurfaceFlinger, System Services, GMS, Android Build System).
Android/Linux graphics stack (EGL, Gralloc, DRM/KMS, Mesa) and graphics driver work.
Web platform technologies: WebAssembly, WebRTC, and the surrounding browser security/sandboxing model.
Containers and virtualization (LXC, namespaces, cgroups) and their interaction with hardware-accelerated graphics.
Real-time network and socket programming, including low-latency streaming protocols and frame pacing.
Linux device driver programming.
