Requirements & Qualifications

• Proficiency in ERC‑4626 and ERC‑4337.
• Experience with consumer/user‑facing applications.
• Production experience with Go.

• Experience with ERC‑7540, ERC‑7579, ERC‑7683.
• Experience with ClickHouse & Dagster.
• Experience with asset management / TradFi (risk, portfolio mgmt, trading systems) strongly preferred.

• Compensation: Base salary up to $175k + equity.

Additional Information

• Client Protocol: A permissionless smart account layer that compresses actions across chains into a single signature.
• Client App: Desktop, iOS, and Android apps that make the protocol accessible through consumer‑grade UX.
• Client Vaults: Institutional‑grade, validator‑secured vaults that dynamically optimize across fixed and variable rate strategies for USD, BTC, and ETH.
• Our client is live across multiple chains, trusted with $130M+ in TVL, 160k+ depositors, and over two years of production uptime with zero exploits. They are backed by leading investors across TradFi and DeFi, including VanEck, Circle, and Polychain.
• With their v2 now live on desktop and mobile launches imminent, they’re looking to expand the backend engineering team foundation.
