About the Job

Requirements

  • Minimum of 5+ years of software engineering experience with a heavy focus on C++ (C++14/17/20).
  • Deep understanding of systems programming, including memory management, multi-threading, and hardware-software abstraction layers.
  • Experience with graphics APIs (OpenGL, Vulkan, or proprietary embedded graphics stacks) and rendering pipelines.
  • Proficiency in Python for tooling and automation, with a working knowledge of BrightScript or JavaScript being a significant plus.
  • Strong root cause analysis skills, specifically using tools like GDB, Valgrind, or platform-specific profilers.
  • Knowledge of AI applications and hands-on experience using generative AI tools to accelerate systems-level development.
  • A proactive mindset with a passion for squeezing every drop of performance out of embedded systems and a commitment to data-driven optimization.

Responsibilities

  • Architect and optimize core C++ UI frameworks and rendering engines to ensure buttery-smooth performance across a diverse range of hardware profiles.
  • Lead technical investigations into system-level bottlenecks, memory leaks, and GPU/CPU synchronization issues.
  • Develop and maintain low-level graphics APIs and layout systems that serve as the backbone for Roku’s application ecosystem.
  • Integrate AI/ML capabilities at the systems level, leveraging generative AI tools to optimize code generation and automate performance profiling.
  • Collaborate with firmware and driver teams to leverage hardware-specific optimizations and ensure seamless integration with the underlying OS.
  • Mentor junior developers through deep-dive code reviews, architectural design sessions, and technical documentation of core systems.
  • Drive engineering excellence by implementing advanced debugging tools, automated performance regression suites, and modern C++ best practices.

Desired Qualifications

  • Proficiency in BrightScript or JavaScript (as a significant plus)
  • Experience with generative AI tools to accelerate systems-level development (if not already required)
  • Experience with embedded hardware optimization and cross-platform graphics pipelines
