Senior Solidity Engineer: ERC-7540 Vault — Byzantine Finance
Description:
We are looking for an expert Solidity dev to model and build an ERC-7540-style vault from our specifications. You’ll design the logic, model the contract, and ultimately deliver clean, production-ready code.

1-2 months of work.
What you’ll do:
- Model vault interactions (deposits, withdrawals, accounting).
- Write efficient Solidity contracts (ERC-7540 compliant).
- Run invariant and fuzz tests (Foundry preferred).
- Document architecture and testing assumptions.
What we’re looking for:
- Deep DeFi experience (vaults, AMMs, lending, yield).
- Mastery of Solidity + EVM internals.
- Strong background in fuzz/invariant testing and contract modelling.
- Proven on-chain deployments or audit-level work.
Nice to have:
- Foundry wizardry, gas optimisation chops, open-source DeFi repos.
