We are working with one of the fastest-growing ventures in the DeFi space – a remote-first, product-led company focused on making decentralized finance accessible to the everyday user.

With estate planning features and a sleek UX, it caters to users transitioning from centralized exchanges into self-sovereign crypto management.


The Role


As a Full Stack Developer, you’ll own the development of end-to-end features with a strong focus on the frontend while ensuring backend stability and scalability.
