Solana Protocol Engineer — On-Chain Settlement & Payments

SOLANA FOUNDATION; International Falls (MN); On-site; USD 120,000 - 190,000; Full time

Job summary

Perena, the risk-layer protocol on Solana, seeks an experienced engineer to design and implement end-to-end funds movement and settlement across on-chain and off-chain systems.

You will build custody, key management, and on-chain flows in Solana (Rust) with cross-chain considerations, ensuring secure, auditable, and scalable infrastructure for USD*. This role demands hands-on experience with financial systems and high-stakes environments.

Qualifications

• 3+ years building financial systems where correctness and settlement guarantees are non-negotiable.
• Experience with on-chain and cross-chain payment flows and custody/settlement.
• Proven track record orchestrating flow of funds across multiple venues with reconciliation and settlement.
• Familiarity with Solana Rust/Anchor or EVM Solidity, and secure key management architectures.

Responsibilities

• Design flow-of-funds orchestration across venues and chains — bridging, routing, rebalancing between custodial and non-custodial systems — with reliable settlement, reconciliation, and failure handling as first-class concerns
• Develop custody and key management patterns that meet institutional-grade security requirements across custodial and non-custodial environments
• Build on-chain settlement and payment flows, including integrations with DEXs, lending markets, custodians, and bridge infrastructure — starting on Solana (Rust) and extending across EVM and other chains as we scale
• Build and maintain the systems that move Perena's money: minting/redeeming USD*, allocating collateral, and routing capital between on-chain protocols, centralized custodians/exchanges, and partner bank rails
