Junior Machine Learning Engineer, HFT Architecture

Remote, Worldwide

HFT Architecture builds short-horizon price prediction and the trading system around it. This role works on the pipeline that turns order-book records into validated models, next to more experienced engineers: data preparation, experiments end to end, and the checks that keep the future out of a training set.

Fully remote, from anywhere in the world. Junior.

Base salary: USD 125,000–155,000 a year.

To apply: a link to your résumé, LinkedIn or GitHub, and one sentence on any of our articles. No file, no cover letter.
