Full-Stack Blockchain Engineer

We are building a new financial layer that reimagines how money moves across the internet. By merging the stability of traditional finance with the programmability of blockchain, we’re creating a powerful stablecoin ecosystem that unlocks access, yield, and utility for users and builders everywhere. Focused on transparency, scale, and real‑world adoption, we’re redefining what digital money can do.

As a Full-Stack Blockchain Engineer, you will play a key role in designing and building the infrastructure and user-facing systems that power a next‑generation stablecoin and programmable money platform. You will work across smart contracts, backend systems, and frontend integrations to create products that combine stability, transparency, and yield in a seamless user experience. This role offers the opportunity to work at the forefront of decentralized finance, bridging traditional financial infrastructure with on‑chain innovation. You will build systems that support real‑world use cases such as global payments, programmable yield, and institutional‑grade capital management, while ensuring security, scalability, and compliance. You will collaborate with a high‑performance team of engineers, product thinkers, and designers to create a product that expands access to secure, yield‑bearing digital dollars for users around the world. Backed by a well‑funded organization, you’ll have the autonomy to innovate and the resources to execute at scale, shaping the foundation of a new financial operating system.
