Blockchain Developer

Own production blockchain work end to end — contracts, integrations, and the systems around them — on BrickFi and client platforms.

This is the senior IC bar for chain engineering at Lootrushs. We staff it when a client needs one person who can hold the whole chain slice: design, implementation, review, deploy order, and what waits for an audit. You still write code. You also split work for a mid engineer. Base is $180k–$220k USD, plus token or equity in the offer. Remote, overlap with US Eastern.

What you will do

• Design, implement, and ship smart contracts and chain integrations.
• Lead reviews, testing, and mainnet deploys across EVM networks we support.
• Partner with product, design, and frontend on wallet and protocol UX.
• Raise the bar for mid-level engineers and launch quality.
• Coordinate testnet → audit → mainnet with Ops (keys, multisig, monitoring).
• Join scoping calls and say what will not fit the date.
• Write the architecture note another engineer can follow six months later.

What you bring

• 4+ years shipping production blockchain software.
• Deep Solidity/EVM (or equivalent chain depth) plus strong TypeScript.
• You have taken protocol or product work through audit and mainnet.

Nice to have

• Foundry
• L2s
• RWA / BrickFi-style products
• Incident response
