Jobbeschreibung

Crebit moves billions across borders on stablecoin rails. Your code holds the customer deposit for every rate lock we ship.

You'll own the Solidity / Anchor contracts that secure FX hedges from 3 hours to 180 days, ship audits, and design the next chain integrations.

About the role

We're a small team building the FX layer that powers cross-border money for fintechs, neobanks, and consumers in 10+ countries. You'll be early: your code will be in production within your first two weeks.

You might be a fit if

• You've shipped production contracts on Solana (Anchor) or an EVM L2, ideally with > $50M TVL.
• You can read your own assembly when something goes sideways at 2 a.m.
• You enjoy the boring parts: tests, fuzzing, formal verification, audits.
• You've done at least one cross-chain integration end-to-end (bridges, oracles, settlement).

What you'll do

• Own the deposit-lock contract on Solana + EVM. Spec, ship, audit.
• Design the cross-chain settlement path with our protocol engineer.
• Write the test suite, hardhat / foundry + property-based fuzzing.
• Work directly with our auditors (Trail of Bits, OtterSec) on release cycles.
• $250K + equity, plus generous early equity.
• Full health, dental, and vision (US-based hires).
• $2,000 annual learning budget.
• Cow Hollow office, SF, lunch + dinner provided.
