Joscha Hoche

Software engineer in London. I’m a Member of Technical Staff at Reflection AI.

Previously, I worked on GPU infrastructure and large-scale compute for AI systems at Isomorphic Labs. Before moving to London from Germany, I completed a PhD in computational quantum chemistry, then built an on-prem HPC platform for around 200 researchers at Merck KGaA.

I’m mostly interested in frontier-scale infrastructure: GPU fleets, scheduling, node health and remediation, reliability, observability, debugging, and the tools research teams need to move fast.

Outside work I usually spend my time on good coffee, interiors*, hiking, running, vegetarian food, and finding my way around a new place.
