Protocol Lead - Rule Enforcement for Regulated Blockchains

Location: remote - north and South America and the EU

Compensation: $180K - $220K

We are building a platform that sets the standard for how regulated blockchain applications enforce transaction rules directly at the smart contract layer. Our system empowers teams to create modular, programmable policies (like AML/CFT checks or off-chain collateral requirements) enforced with cryptographic guarantees before a transaction executes on-chain. We are seeking a Protocol Lead to own the entire smart contract suite, driving robust, scalable risk management for real-world use cases.

As the Protocol Lead, you will have full ownership of the architecture, development, and maintenance of our core smart contract suite. You will be the team's blockchain subject matter expert, defining security best practices, managing audits, and building tooling for seamless integration. This role requires a balance of hands-on coding, security leadership, and cross-ecosystem research (EVM and non-EVM).

Key Responsibilities:

Principal Engineer (Remote Outside US) - Real-World Asset Minter Infrastructure

Location: Remote - Europe or on the East Coast for South America/Canada (No US)

Compensation: $200K - $225K

We are building a critical piece of infrastructure that is the first live Minter on a major protocol. Our system transforms real-world collateral, such as U.S. Treasuries, into on-chain monetary building blocks ($M). This programmable, composable foundation allows builders to create their own application-specific digital dollars. We are seeking a Principal Engineer to take full-stack ownership of the systems that power this creation and distribution.

This role begins as a high-impact Senior Individual Contributor position with broad autonomy to define architecture and set engineering practices, designed to grow into a technical leadership role. You will work directly with leadership to execute a clear, productized system vision. Your focus will be on building the institutional-grade infrastructure that enables automated minting, multi-chain liquidity, and key integrations.
