Senior React Native Engineer

About Argent

Argent aims to be crypto’s defining company: the first to bring the benefits of self-custody to a global audience. Giving people control of their assets and identity, and helping them to enjoy new economic opportunities.

To do this we’ve built the first smart wallet. As different from traditional wallets as smart phones were to 90’s phones. Argent is easier, safer, cheaper, and greener.

With over 2m users we’re growing fast. And have raised a total of $56m from Paradigm, Index Ventures and Creandum to fuel our ambitious efforts.

We work remotely across Europe, prioritizing autonomy and flexibility. And it’s a particularly exciting time to join as we’re launching new breakthrough products on Starknet.
