Member of Technical Staff (Smart Contract)

Join Galaxy, a leading company in the crypto space, as a Member of Technical Staff (Smart Contract). In this role, you will be responsible for the contract and program layer of systems that institutions rely on, including tokenized funds, staking and validator infrastructure, and compliance primitives. You will work end-to-end on each system, from specification to deployment tooling, monitoring, and off-chain integrations. You will also build compliance and control surfaces for regulated institutions and drive the security posture of your work. This position offers equity exposure, 401(k) contributions, flexible time off, full paid health benefits, and various perks.

• Design, implement, and ship smart contracts and on-chain programs across EVM and Solana for tokenized funds, staking systems, and capital markets primitives.
• 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.
• Drive the security posture of what you ship — threat modelling, invariant and fuzz testing, internal review, and working with external auditors.
• 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
• High agency, low ego. You own your work end-to-end and hold yourself accountable for quality
• 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
• 4+ years of production engineering experience, with substantial time spent shipping smart contracts or on-chain programs that handle real value
• Comfort owning systems end-to-end, including the off-chain pieces that production contracts depend on
• Ability to operate in a high-autonomy environment
• 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
