Our products are utilized by companies in designing and optimizing technology products, with applications ranging from designing airplanes and cars to wind turbines and quantum computing chips. Our customer base includes both household names and startups in emerging industries. Our company was founded by world-renowned leaders in simulation technology from Stanford University and MIT. Backed by top VC firms, we are poised to disrupt the billion-dollar engineering simulation industry with our fast-growing trajectory\n\nJob Summary:\nFlexcompute is seeking an experienced software developer to contribute to a modern Computational Fluid Dynamics simulation software designed for multi-node CPUs and GPUs. The successful candidate will have a critical role in designing and implementing cutting-edge algorithms with an emphasis on speed, robustness, accuracy, and scalability. This position offers a unique opportunity to explore state-of-the-art CFD and computational geometry algorithms in a production environment. The candidate will gain experience working with highly experienced professionals and be an integral part of the product development, release, maintenance, and support phases. Over time, the strong collaborative nature of this role offers exposure to Flexcompute’s sophisticated multi-physics simulation and design optimization technologies.\n\nWhat You Will Do:\n\nIndependently implement, test, and document new solver and meshing features\n\nProfile and optimize feature implementation to improve speed and scalability on CPUs/GPUs\n\nContribute to a clean and maintainable API for various functionalities\n\nContribute to general source code maintenance and other relevant software development activities (bug fixes, support, etc)\n\nCollaborate with teams developing the user-interface and scientific visualization tools/technologies\n\nCollaborate with Product Management, QA, and Documentation teams to accomplish product milestones in a timely manner\n\nFollow sound software engineering practices. The code we write today will underpin our platform simulation products for years to come – it needs to be maintainable, extensible and robust\n\nMake user experience a priority.
