Smart Contract Engineer

RegistryChain is building the trust-neutral social fabric through universal verified facts (Entity.ID) and the compilation of legally binding agreements into computationally binding ones.

We enable normies to collaborate across the globe by co-founding ventures in a predictable, trustless way; households to protect family rights independently of states and governments; and society to navigate relationships with frontier entities — such as AI and humanoids — while safeguarding social order in an evolving world.

The problems we work on sit at the intersection of law, cryptography, artificial intelligence, political science, governance, and social systems. We build real-world applications on blockchain while abstracting the blockchain away entirely, enabling trustless collaboration with institutional reliability.

This work demands rigor, taste, and a willingness to take responsibility for long-lived infrastructure. We’re looking for fundamental thinkers willing to stretch their limits and build things meant to outlive hype cycles.

About You

You are a Solidity-first smart contract engineer who enjoys working close to the EVM, where correctness, security, and long-term maintainability matter more than clever abstractions.

You have strong proficiency in Solidity (≥0.8.x) and a deep understanding of Ethereum’s execution model, including storage layout, gas mechanics, access control, and upgrade patterns. You’re comfortable reasoning about invariants, edge cases, and failure modes, and you write contracts intended to be long-lived, audited, and relied upon in production.

You are fluent with modern Ethereum development workflows and tooling, including Foundry and/or Hardhat, and familiar with security and analysis tools such as Slither, Echidna, and audit-driven review processes. You value testing, documentation, and clear reasoning as much as implementation.

You’re motivated by encoding real-world governance, ownership, compliance, and identity constraints as explicit, enforceable on-chain logic. This includes experience or strong interest in DAO systems, KYC or identity-aware mechanisms, and compliance-sensitive protocol design.

Nice to have (not required):
Experience with ENS or ENS-like naming systems, familiarity with off-chain resolvers, indexers, or oracle-assisted resolution, experience with Vyper, ability to read Yul or inline assembly, prior work on DAO frameworks or registry protocols, exposure to audits or formal verification, open-source protocol contributions, or a background spanning protocol engineering and applied research.

You’ll Do

You’ll design, build, and maintain smart contract systems that define how entities exist, identify themselves, and govern their actions. This includes entity accounts, registries, and resolver systems, as well as on-chain governance modules for membership, proposals, voting, amendments, and compliance.

Your work encodes real-world rules around ownership, decision-making, accountability, and identity, including KYC- and attestation-aware mechanisms, directly into code. These systems must remain secure, auditable, and safely upgradeable over time.

You’ll Get

In addition to salary, early-stage equity, a flexible remote work environment built on autonomy and trust, and direct impact building core Web3 protocols that solve real-world problems for the next generation of the trust-neutral social fabric.
