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., We are seeking a Software Optimization Engineer with deep experience improving realworld browser performance in Chromiumbased 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 lowlevel performance analysis, systemlevel optimization, and collaborative work with browser, OS, and silicon teams to deliver measurable uservisible gains., * Profile and optimize performance across Chromium subsystems, including Blink, V8, Skia, GPU/ANGLE, and browser multiprocess 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 industrystandard 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 cooptimize software and platforms * Contribute clean, wellreviewed 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, AMD may use Artificial Intelligence to help screen, assess or select applicants for this position.
