Job Description
Principal Graphics Engineer responsible for graphics rendering stack in mobile app technology. Collaborating within a small, agile team from an AI-native organization.
Responsibilities:
- 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:
- 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.
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
