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:

Youll 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. Youll 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 Youll 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 Edges on-chain products

What Were 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 youve 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.

Bonus Points:

• Experience with tokenized assets regulated financial products or institutional DeFi.
• Familiarity with tokenized vault standards (ERC-4626 ERC-7540 for asynchronous deposit/redemption flows) and Token-2022 extensions such as transfer hooks.
• Background in capital markets custody or staking infrastructure.
• Prior work that has been through formal audit.
