About The Position

Bright Vision Technologies is seeking a GPU Software Engineer with deep expertise in CUDA programming, GPU architecture, and high-performance computing to design and optimize compute-intensive workloads on modern accelerator hardware. The role focuses on extracting maximum performance from GPU platforms for AI training, inference, scientific computing, and high-throughput data processing. The successful candidate will bring low-level systems expertise, strong software engineering practices, and a track record of delivering measurable performance improvements on production GPU systems. The engineer will work with product, design, engineering, operations, and business stakeholders to translate ambiguous requirements into well-engineered solutions. The role also includes contributing to code and design reviews and mentoring more junior engineers. Strong engineering discipline, clear communication, and a history of shipping production-quality work are expected. This is a full-time, direct W2 position that is 100% remote in the United States. The salary range is $100,000–$175,000 annually. The employer cannot sponsor new H-1B visa petitions; U.S. citizens, green card holders, EAD holders, and H-1B transfer candidates are encouraged to apply.
