WHAT YOU DO AT AMD CHANGES EVERYTHING

At AMD, our mission is to build great products that accelerate next-generation computing experiences—from AI and data centers, to PCs, gaming and embedded systems. Grounded in a culture of innovation and collaboration, we believe real progress comes from bold ideas, human ingenuity and a shared passion to create something extraordinary. When you join AMD, you’ll discover the real differentiator is our culture. We push the limits of innovation to solve the world’s most important challenges—striving for execution excellence, while being direct, humble, collaborative, and inclusive of diverse perspectives. Join us as we shape the future of AI and beyond.

Together, we advance your career.

THE ROLE:

AMD is looking for a strategic software engineering lead who is passionate about improving the performance of key applications and benchmarks. You will be a member of a core team of incredibly talented industry specialists and will work with the very latest hardware and software technology.

THE PERSON:

We are seeking a Software Optimization Engineer with deep experience improving real‑world browser performance in Chromium‑based browsers. In this role, you will focus on identifying, analyzing, and resolving performance bottlenecks across the Chromium stack, working close to the browser engine, OS, and hardware. This position is ideal for an engineer who enjoys low‑level performance analysis, system‑level optimization, and collaborative work with browser, OS, and silicon teams to deliver measurable user‑visible gains.

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 workloads, benchmarks, and field telemetry.
• Implement performance improvements in areas such as page load, rendering, JavaScript execution, graphics/compositing, and browser responsiveness.
• Drive optimizations across platforms (Windows primary; Linux/macOS experience a plus), including interactions with OS schedulers, graphics stacks, and drivers.
• Analyze performance using industry‑standard and custom tools (e.g., Perfetto, ETW, Chrome Tracing, VTune, PIX, GPUView, perf).
• Collaborate with browser vendors, OS teams, compiler teams, and hardware partners to co‑optimize software and platforms.
• Contribute clean, well‑reviewed patches upstream to Chromium or downstream forks as appropriate.
• Translate benchmark and microarchitectural findings into practical, scalable browser improvements.
• Document performance investigations, results, and best practices; communicate findings clearly to technical stakeholders.
• Software engineering experience, with a strong focus on performance optimization.
• Hands‑on experience working with Chromium or Chromium‑based browsers (e.g., Chrome, Edge, internal forks).
• Strong proficiency in C++ and modern C++ performance best practices.
• Deep understanding of browser internals, including at least two of the following:
• Rendering pipeline (Blink lifecycle, style/layout/paint)
• JavaScript engines (V8 internals, JIT behavior, GC)
• Graphics and compositing (Skia, GPU rasterization, ANGLE, WebGL)
• Multiprocess/threading model and IPC in Chromium
• Proven experience using low‑level profiling and tracing tools to drive optimizations.
• Strong debugging skills across large, complex codebases.
• Ability to reason from microarchitectural behavior (cache, memory, SIMD, branch behavior) up to user‑perceived performance.

Preferred Qualifications

• Experience optimizing browser performance on Windows, including ETW‑based analysis and graphics stack interactions.
• Familiarity with Clang/LLVM, compiler‑driven optimizations, and code‑generation tradeoffs.
• Experience working with performance benchmarks (JetStream, Speedometer, WebXPRT, MotionMark, internal workloads).
• Exposure to hardware‑aware optimization (CPU topology, cache behavior, SIMD/AVX, GPU execution models).
• Prior experience contributing to large open‑source projects or upstream Chromium performance changes.
• Ability to mentor junior engineers and influence performance culture across teams.

ACADEMIC CREDENTIALS:

• Bachelor’s or Master's degree in Computer Science, Computer Engineering, Electrical Engineering, or equivalent.

This role is not eligible for visa sponsorship.
