MXON is the first live Minter on the M0 Protocol, operating the infrastructure that transforms real-world collateral like U.S. Treasuries into onchain monetary building blocks - $M. $M is M0’s programmable, composable foundation for builders to create their own application-specific digital dollars via M0’s $M Extensions. MXON was incubated and funded by the M0 project, and grew to become the first Minter on the M0 network.

This role starts as a senior individual contributor position, with full-stack ownership and meaningful scope, but is designed to grow into a technical leadership role as the team scales. Please note: This position is open only to candidates who are based outside of the United States.

You'll work directly with the Head of MXON and M0’s Chief Technical Officer to execute on a clear, productized system vision, and have broad autonomy to define architecture, set engineering practices, and shape the long-term technical direction of the Minter stack.
