Role Description
We are seeking a passionate and resilient Principal Graphics Engineer to own a foundational piece of our infrastructure: the rendering and runtime layer that lets unmodified mobile apps execute and stream pixel-perfect, low-latency experiences to any browser.
-
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.
This is a technically demanding role that rewards resilience, creative problem-solving, and out-of-the-box thinking.
Qualifications
-
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.
Requirements
-
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.
Nice-to-Haves
-
Experience building, fine-tuning, or evaluating internal AI/agent tooling that augments engineering work.
-
A data-driven mindset, relying on qualitative and quantitative signal to make informed decisions.
-
Mobile game development experience, including engines, SDKs, and the broader ecosystem.
-
Background in advanced compression, video codecs, or color management.
-
Graduate work or research background in computer graphics, systems, or a related area.
Benefits
-
Group Retirement Savings Plan matching and participation.
-
Comprehensive benefits package (health, dental, vision), including Health and Wellness spending account.
-
Generous time off policies.
-
Access to leading AI tools and platforms.
