You ll move between protocol-level design work and shipping production contracts that clear institutional audit, security, and operational bars. You own your work end-to-end: spec, contracts, tests, deployment tooling, monitoring, runbooks, and the off-chain integrations that make contracts operable in production. br> br> strong>What You ll Do br> br> /strong>Design and ship on-chain systems br> br> ul> li>Design, implement, and ship smart contracts and on-chain programs across EVM and Solana for tokenized funds, staking systems, and capital markets primitives. /li> li>Own contract-level architecture decisions: upgrade paths, access control, transfer restrictions, oracle integration, fee and accounting logic, and failure modes. /li> li>Work end-to-end on each system - from spec through to deployment tooling, monitoring, runbooks, and the off-chain integrations that make contracts operable in production. br> br> /li> /ul>Build for regulation institutions br> br> ul> li>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. /li> li>Translate ambiguous product or regulatory requirements into concrete contract designs without heavy process. br> br> /li> /ul>Own security and rigor br> br> ul> li>Drive the security posture of what you ship - threat modelling, invariant and fuzz testing, internal review, and working with external auditors. /li> li>Contribute to technical research that shapes the next generation of Edge s on-chain products br> br> /li> /ul> strong>What We re Looking For br> br> /strong> ul> li>4+ years of production engineering experience, with substantial time spent shipping smart contracts or on-chain programs that handle real value. /li> li>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. /li> li>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. /li> li>Comfort owning systems end-to-end, including the off-chain pieces that production contracts depend on. /li> li>Ability to operate in a high-autonomy environment. /li> li>High agency, low ego. You own your work end-to-end and hold yourself accountable for quality. br> br> /li> /ul> strong>Bonus Points br> br> /strong> ul> li>Experience with tokenized assets, regulated financial products, or institutional DeFi. /li> li>Familiarity wit
