Principal Graphics Engineer

About the Role

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.

You will spend your time deep in graphics pipelines, shaders, GPU compositing, frame timing, and the cross-stack interactions between Android/Linux graphics, browser engines, and WebGL/WebGPU. The role demands first-principles thinking, an instinct for getting to the root of difficult problems, and the maturity to ship performance-critical code that holds up at scale.

We are equally interested in candidates with a deep graphics engineering background (game engines, browser graphics, GPU systems, real-time rendering) and candidates from adjacent low-level systems backgrounds with demonstrated graphics depth.

• 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.

This is a technically demanding role that rewards resilience, creative problem‑solving, and out‑of‑the‑box thinking.

• 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 Direct
  
  X, 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, Web Kit), 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, Surface Flinger, System Services, GMS, Android Build System).
• Android/Linux graphics stack (EGL, Gralloc, DRM/KMS, Mesa) and graphics driver work.
• Web platform technologies:
  Web Assembly, WebRTC, and the surrounding browser security/sandboxing model.
• Containers and virtualization (LXC, name spaces, 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.

• 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.

• 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
