About:

Veda is the DeFi engine powering financial apps enabling platforms to seamlessly create on-chain yield products. Our mission is to unlock DeFi for the world by providing seamless, enterprise-grade integrations for modern finance. Veda's technology powers many of DeFi's largest vault products, including ether.fi Liquid, PlasmaUSD Vault, Lombard DeFi Vault, and Mantle cmETH.

At $6B in TVL and 100k+ users, Veda is one of the fastest growing DeFi protocols with a team passionate about DeFi and dedicated to our work. This role will be high impact and have the opportunity to directly shape some of the most critical infrastructure in DeFi.

Role:

As a Smart Contract Engineer, you will contribute to our Solidity engineering organization — architecture, delivery, and security for all on-chain code. You will help to uphold world-class security and reliability standards for contracts securing ten-figure TVL.

We seek individuals with high agency to join us in defining the next phase of DeFi growth and adoption. The ideal candidate takes ownership, thrives in a fast-paced environment, and adapts swiftly to evolving demands.

Responsibilities:

Contribute to all Solidity codebases, including upgrade patterns, proxy architecture, account abstraction, and cross-chain messaging.
Drive rigorous design reviews, threat modeling, fuzz testing, and formal verification to achieve “audit-by-design” security
Continuous deployment, maintenance, and upgrades of existing vaults
Own end-to-end delivery of new protocol features
Manage external auditors and bug-bounty programs; implement on-chain monitoring and incident-response playbooks
Represent Veda in client integrations, conferences, and the broader open-source community

What you'll bring:

6+ years of software engineering experience
2-3+ years writing production Solidity (ERC-20/4626, custom libraries, proxy & upgrade patterns)
Track record of creating or maintaining a contract suite without critical incidents
Knowledge of EVM internals, gas optimization, storage layout, and common smart-contract exploits (re-entrancy, oracle manipulation, MEV)
Fluency with Foundry and/or Hardhat,
Excellent written and verbal English; comfortable presenting to executives, auditors, and the wider community

Preferred Skills & Experience:

Familiarity with multi-chain DeFi interactions and cross-chain messaging standards
Professional experience using Rust
Experience using Move-based smart-contract platforms (Aptos) would be a huge plus also.
Background in traditional finance, risk, credit, or derivatives a plus
Active contributor to open-source security research, EIPs, or protocol governance
Formal-verification expertise
Experience with audit cycles with top-tier firms (e.g., Trail of Bits, Spearbit)
