About the Role
You will own the design and implementation of new on-chain primitives across Ethereum and Solana including staking flows validator orchestration vault strategies exit and redemption mechanisms and integrations with institutional custody. You will drive the audit lifecycle end to end scoping engagements triaging findings implementing remediations and shepherding code to mainnet deployment. You will set and enforce the engineering bar within your team including testing standards review processes deployment runbooks incident response and on-call rotations for live contracts. You will partner with product and engineering leadership to translate enterprise-grade requirements into on-chain designs that hold up to scrutiny from bank-grade counterparties. You will mentor smart contract engineers on your team and contribute to hiring code review culture and career development across the broader smart contract function. You will represent on-chain work externally with auditors institutional clients governance forums and the broader Ethereum and Solana ecosystems. You will embrace and champion the thoughtful adoption of AI to improve team performance and business outcomes. You will leverage AI tools to improve productivity decision-making and output quality in your day-to-day work.
Requirements
- 7+ years of professional software engineering experience with at least 4 years writing production smart contracts deployed at meaningful TVL across both Ethereum (Solidity) and Solana (Rust/Anchor).
- Deep expertise in EVM internals gas optimization and proxy upgradeability patterns such as UUPS Transparent and Beacon plus working knowledge of Solana program development account models and PDA design.
- A track record of shipping contracts that have cleared third party audits and familiarity with formal verification tooling such as Certora Prover Halmos or Kontrol.
- Fluency with modern tooling across both chains including Foundry Hardhat Slither Echidna on the EVM side and Anchor Solana program test frameworks and fuzzing tools on the Solana side.
- Hands-on experience across multiple on-chain domains relevant to institutional infrastructure including liquid staking validator economics slashing mechanics tokenized vault ERC4626 architectures custody integrations or settlement and redemption flows.
- A security-first mindset and the judgment to know when to slow down ship and design for failure modes such as pause mechanisms circuit breakers and containment modes.
- Demonstrated depth owning complex architecture decisions end to end maintaining a high bar for code review and testing and supporting other engineers through audits incidents and production deployments.
- Strong written communication able to explain subtle reentrancy oracle staleness or account validation risk clearly to engineers auditors product and enterprise counterparties.
- AI fluency you have integrated AI into how you work and can speak concretely about tools you use what you have built or accelerated and the risks of using AI-generated code in a smart contract context.
- High agency you see what needs to happen and make it happen and are comfortable with incomplete direction and accountability for outcomes.
