Description

As a Senior Software Engineer on the UI Systems team, you will design and implement performance-critical C++ code for Roku's UI engine, optimizing graphics rendering and memory management across diverse hardware. You'll tackle complex systems-level challenges, integrate AI/ML for code generation, and collaborate with firmware teams to push the boundaries of embedded TV streaming.

Requirements

• 5+ years of software engineering experience with heavy focus on C++ (C++14/17/20)
• Deep understanding of systems programming: memory management, multi-threading, hardware-software abstraction
• Experience with graphics APIs (OpenGL, Vulkan, or proprietary embedded graphics stacks) and rendering pipelines
• Proficiency in Python for tooling and automation
• Strong root cause analysis skills using GDB, Valgrind, or platform-specific profilers

Responsibilities

• Architect and optimize core C++ UI frameworks and rendering engines for buttery-smooth performance
• Lead technical investigations into system-level bottlenecks, memory leaks, and GPU/CPU synchronization
• Develop and maintain low-level graphics APIs and layout systems
• Integrate AI/ML capabilities to optimize code generation and automate performance profiling
• Mentor junior developers through code reviews and architectural design sessions
