Senior Designated Support Engineer

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.

Backed by a $300M investment from Blackstone at a $5B valuation, and working alongside partners including NVIDIA, Supermicro, and Google Cloud, DDN is a well-established business currently going through genuine transformation.

You'll act as the senior technical expert for a portfolio of DDN's largest and most strategic global customers. This is a named-account role, not a general support queue - you'll build lasting relationships and take ownership of complex, large-scale Lustre parallel file system environments from end to end.

You'll join a team of 7 experienced engineers, growing by 3 further hires, working alongside deep specialists in Lustre and parallel file systems. You'll also collaborate closely with DDN's engineering and education teams, contributing directly to product improvements and customer training.

Fully remote. Fully self-managed. We're not interested in watching you work - we're interested in you owning it. Some travel and on-site work when it counts, plus a fair, once-per-team-cycle on-call rotation
