Senior Full-stack Engineer

Who We Are
‍
We’re 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, scalability, and real-world adoption, we’re redefining what digital money can do.
‍

The Role
‍
As a Full-Stack Blockchain Engineer, you’ll 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’ll 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 operate at the forefront of decentralized finance, bridging traditional financial infrastructure with on-chain innovation. You’ll 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’ll collaborate with a high-performance team of engineers, product thinkers, and designers to expand access to secure, yield-bearing digital dollars worldwide. 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.
