Sua plataforma oferece aos usuários uma experiência rápida e fluida, sem a necessidade de app stores ou instalações, promovendo um ambiente web livre e sem restrições. Apoiada por empreendedores em série experientes e investidores renomados, a Parallelz busca criar uma internet melhor para todos, oferecendo maneiras totalmente novas de aprimorar as experiências online.

Descrição

• 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.

🎯 Requisitos

• 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.
