Work on something
built to last.
QuantSpire AI is a small, private, research-stage platform. We hire slowly and for the long term: people who like being measured against criteria they helped write, who prefer honest negative results to flattering ones, and who treat risk as the first design constraint, not the last.
Remote-first. We read every application ourselves.
Roles we are looking for
Statistics and time series on market data; designing tests that can fail; writing up what you found either way.
Training, evaluation and operation of models under strict out-of-sample discipline; reproducible pipelines.
Python services, data pipelines, cloud infrastructure, observability; systems that fail safely.
Web application and design system for a demanding, information-dense product.
Nothing that fits? Send a general application and tell us what you do best.
