Browser Optimization Engineer

AMD - Advanced Micro Devices

Gdansk, Poland

THE ROLE:

As a Browser Optimization Engineer, you will play a critical role in driving real-world browser performance improvements across Chromium-based platforms. Working at the intersection of browser engines, operating systems, and hardware, you will identify and resolve performance bottlenecks that directly impact millions of users.

This role offers the opportunity to work deeply within Chromium subsystems such as Blink, V8, Skia, and GPU layers, while collaborating with browser, OS, compiler, and silicon teams to deliver measurable, user-visible gains. You will operate in a highly collaborative, systems-focused environment where your work translates directly into faster, more responsive web experiences.

THE PERSON:

You are a performance-focused engineer who enjoys digging into complex systems and uncovering root causes of inefficiency. You are naturally curious, data-driven, and comfortable working across large, multi-layered codebases.

You thrive in collaborative environments, working effectively with cross-functional teams spanning software, operating systems, and hardware. You communicate clearly, translate technical insights into actionable improvements, and are motivated by delivering measurable impact to end users.

KEY RESPONSIBILITIES:

Profile and optimize performance across Chromium subsystems, including Blink, V8, Skia, GPU/ANGLE, and browser multi-process architecture;
Identify CPU, memory, GPU, and power bottlenecks using real-world workloads, benchmarks, and telemetry;
Implement improvements in areas such as page load performance, rendering, JavaScript execution, graphics/compositing, and responsiveness;
Drive cross-platform optimizations, with a primary focus on Windows and exposure to Linux/macOS environments;
Analyze system behavior using tools such as Perfetto, ETW, Chrome Tracing, VTune, PIX, GPUView, and perf;
Collaborate with browser vendors, OS teams, compiler teams, and hardware partners to co-optimize software and platforms;
Contribute high-quality patches to Chromium or related codebases where appropriate;
Translate low-level profiling insights into scalable, user-facing performance improvements;
Document findings and communicate results clearly to technical stakeholders.

PREFERRED EXPERIENCE:

Strong background in software engineering with a focus on performance optimization;
Experience working with Chromium or Chromium-based browsers (e.g., Chrome, Edge, or internal forks);
Proficiency in C++ and modern performance-oriented development practices;
Understanding of browser internals across areas such as:
- Rendering pipelines (e.g., Blink lifecycle, layout, paint);
- JavaScript engines (e.g., V8, JIT behavior, garbage collection);
- Graphics and compositing (e.g., Skia, GPU rasterization, ANGLE, WebGL);
- Multi-process architectures and IPC models.
Experience using profiling and tracing tools to drive optimization decisions;
Strong debugging skills within large-scale, complex systems;
Ability to connect microarchitectural behavior (cache, memory, SIMD, branching) to real-world performance outcomes;
Familiarity with Windows performance analysis (including ETW) and graphics stack interactions;
Exposure to Clang/LLVM and compiler-driven optimizations;
Experience with performance benchmarks such as JetStream, Speedometer, WebXPRT, or MotionMark;
Awareness of hardware-aware optimization techniques (CPU topology, cache behavior, SIMD/AVX, GPU execution models);
Experience contributing to large-scale or open-source codebases;
Ability to mentor others and influence performance best practices across teams.
