Salary: £60,000 - 100,000 per year
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 (e.g., 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 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 our 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.
