Senior ML Engineer (AI Research)

[…] is leading a new era in cloud infrastructure for the global AI economy. We are building a full-stack AI cloud platform that supports developers and enterprises from data and model training through to production deployment, without the cost and complexity of building large in-house AI/ML infrastructure.

Built by engineers, for engineers. From large-scale GPU orchestration to inference optimization, we own the hard problems across compute, storage, networking and applied AI.

Listed on Nasdaq (NBIS) and headquartered in Amsterdam, we have a global footprint with R&D hubs across Europe, the UK, North America and Israel. Our team of 1,500+ includes hundreds of engineers with deep expertise across hardware, software and AI R&D.

This role is for […] AI R&D, a team focused on applied research in AI. Examples of applied research that we have recently published include:

applying reinforcement learning for agent training in long-context multi-turn scenarios

dramatically scaling task data collection to power reinforcement learning for SWE agents

building a decontaminated evaluation for SWE agents that is regularly updated

investigating how test-time guided search can be used to build more powerful agents

The results often lead to collaboration with adjacent teams where our research findings are applied in practice.

We are currently looking for senior- and staff-level ML engineers to work on research in areas such as:

Guided search and reinforc
