[Hiring] Blockchain Engineer @Consensys

Role Description

We are seeking a Blockchain Engineer to join our Treasury team, focused on building and maintaining on-chain infrastructure to support liquidity management, cash operations, custody, and risk management. This role will design and implement smart contract solutions, automation pipelines, and integrations with custodial and non-custodial wallets to ensure secure, scalable, and compliant treasury operations.

• Design, build, and audit smart contracts to automate treasury workflows, including rebalancing, cross-chain swaps, and bridging.
• Build systems to consolidate and monitor balances across EOAs, Safe/MPC wallets, custodians, and DeFi protocols.
• Automate recurring transactions (e.g., stablecoin conversions, revenue rebalancing) aligned with treasury policy targets.
• Integrate on-chain infrastructure with Treasury Management Systems (e.g., Kyriba) for unified reporting across fiat, custodial, and non-custodial accounts.
• Develop APIs and middleware to ensure seamless interaction between blockchain networks and internal systems.
• Support risk management with real-time visibility into protocol-level exposures, credit/counterparty risk, and liquidity positions.
• Work closely with Treasury, Finance, Security, and Product teams to translate policy and risk requirements into technical solutions.
• Partner with custodians, auditors, and external vendors (e.g., MPC providers like Fireblocks/FORDEFI) for integration and compliance.

Qualifications

• Bachelor’s or Master’s in Computer Science, Engineering, or related field.
• 3–5+ years of blockchain development experience (Solidity, Rust, or similar).
• Hands-on experience with smart contract development, auditing, and deployment on Ethereum and/or other major chains.
• Strong knowledge of DeFi protocols, liquidity pools, bridges, and stablecoins.
• Experience with custodial and non-custodial wallet infrastructure (EOA, MPC, multi-sig).
• Proficiency with APIs, Python/TypeScript, and DevOps tooling for automation.
• Understanding of treasury operations, cash management, and financial risk is a plus.

Requirements

• Experience with Treasury Management Systems (TMS) integration.
• Prior work in fintech, digital asset exchanges, or institutional crypto custody.
• Strong security mindset: ability to identify and mitigate smart contract and infrastructure risks.

Impact & Success Metrics

• Reduction of manual treasury transactions and approvals.
• Improved visibility of on-chain balances, flows, and risks.
• Successful automation of revenue rebalancing and cross-chain liquidity management.
• Increased capital efficiency (minimizing idle assets, optimizing protocol usage).
