What We Value: We are a diverse team of free thinkers, and fast movers united to help investors and creators energize the global economy. We are looking for individuals who thrive in a culture of builders and overachievers and embrace high performance, transparent feedback, and a mission-first approach. Our culture shapes our way of working and gets us where we want to be. Seek Excellence. Be Selective To Be Effective. Be Highly Aligned, Loosely Coupled. Disagree Transparently. Encourage Independent Decision-Making. Build Dream Teams. Who You Are: You'll 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. This is a builder role with a research dimension. 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. What You’ll Do: Design 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 to deployment tooling, monitoring, runbooks, and the off-chain integrations that make contracts operable in production. Build for regulation institutions 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. Own security and rigor 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 Edge's on-chain products What We’re Looking For: 4+ years of production engineering experience, with substantial time spent 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…
