Just is an ambitious startup which is uniquely poised to change how global corporations trade foreign currency. We are focused on bringing transparency and accessibility to an industry which is ripe for disruption, by delivering modern, high-performance software allowing companies to price and execute foreign exchange trades in real time at market rates.

We recently completed a large funding round, backed by top angel investors and a bank, and our team is growing rapidly. We are seeking enthusiastic, forward-thinking software engineers to help us build one of the most challenging (and interesting) types of software system in the tech industry.
