About the Role

The SandboxAQ R&D team is looking for a ML Research Engineer to help us bring more AI to the domain of cybersecurity. This includes applying AI in the domain of traditional cybersecurity ("AI for security"), as well as securing AI-first developer workflows ("Security for AI"). A successful candidate will be comfortable building models from scratch, finetuning existing ones, and running inference efficiently (both generative and quantitative). They will be able to design software systems around those models in close collaboration with our engineering department. Candidates should be familiar with the AI development process and be able to identify potential pitfalls and (security) issues. They will be part of a diverse team consisting of ML experts, cryptographers, mathematicians, and physicists, where they will play a key role in efficient and effective enablement of the cutting-edge technologies being developed at SandboxAQ.
