Senior Designated Support Engineer

Job description

DDN has been a trusted name in high-performance data storage for over 25 years, with technology deployed across 48 of the world's top 100 supercomputers. That long track record now sits at the centre of one of the most significant infrastructure shifts in a generation: the AI boom has created unprecedented demand for exactly the kind of high-performance storage DDN has spent decades perfecting.
