Member of Technical Staff - Smart Contract

You will own the contract and program layer of systems that real institutions depend on — tokenized funds, staking and validator infrastructure, collateral and liquidity products, and the compliance primitives that make them usable inside regulated workflows. You will design, implement, and ship on-chain contracts across EVM and Solana, including upgrade paths, access control, transfer restrictions, oracle integration, fee and accounting logic, and failure modes. You will work end to end from specification through deployment tooling, monitoring, runbooks, and the off-chain integrations that make contracts operable in production. You will build the compliance and control surfaces that let regulated institutions actually use these systems — KYC/AML enforcement at the protocol layer, role-based access, investor-class restrictions, and auditable mint/burn/transfer flows. You will translate ambiguous product or regulatory requirements into concrete contract designs without heavy process. You will drive the security posture of what you ship — threat modelling, invariant and fuzz testing, internal review, and working with external auditors. You will contribute to technical research that shapes the next generation of on-chain products.

Responsibilities

Design, implement, and ship on-chain systems.
Design, implement, and ship smart contracts and on-chain programs across EVM and Solana for tokenized funds, staking systems, and capital markets primitives.
Own contract-level architecture decisions: upgrade paths, access control, transfer restrictions, oracle integration, fee and accounting logic, and failure modes.
Work end-to-end on each system — from spec through deployment tooling, monitoring, runbooks, and the off-chain integrations that make contracts operable in production.
Build the compliance and control surfaces that let regulated institutions actually use these systems — KYC/AML enforcement at the protocol layer, role-based access, investor-class restrictions, and auditable mint/burn/transfer flows.
Translate ambiguous product or regulatory requirements into concrete contract designs without heavy process.
Drive the security posture of what you ship — threat modelling, invariant and fuzz testing, internal review, and working with external auditors.
Contribute to technical research that shapes the next generation of on-chain products.

Requirements

4+ years of production engineering experience, with substantial time shipping smart contracts or on-chain programs that handle real value.
Deep fluency in at least one of Solidity (Foundry/Hardhat, EVM internals, upgrade patterns) or Solana programs (Rust, Anchor, Token-2022, SPL); credible working knowledge of the other, or a clear track record of picking up new chain ecosystems quickly.
Strong instincts for smart contract security — you've thought hard about reentrancy, oracle manipulation, access control, and the failure modes specific to your stack, and you write code that reflects it.
Comfort owning systems end-to-end, including the off-chain pieces that production contracts depend on.
Ability to operate in a high-autonomy environment.
High agency, low ego. You own your work end-to-end and hold yourself accountable for quality.
