A Heterogeneous Systems Developer designs, develops, and optimizes computing systems that utilize diverse, multiple processing units. These units can include CPUs, GPUs, and other types of processors. The developer ensures these units function together seamlessly, maximizing their performance and efficiency. They work on tasks such as system architecture design, algorithm development, programming, debugging, and performance tuning. They must have a deep understanding of different hardware architectures, parallel programming models, and system software. Their work is crucial in areas like high-performance computing, artificial intelligence, and data analytics, where processing large amounts of data quickly is essential.
