Job description

About us

Ether.fi is an innovative, rapidly growing crypto-native financial platform on a mission to put users in control of their wealth—making it easy to save, earn, and spend crypto. Positioned as a leading decentralized finance (DeFi) bank, ether.fi offers a fully integrated, non-custodial suite of products—Stake, Liquid, and Cash—that bridge crypto utility with real-world convenience. With over $10B in TVL and a lean, agile team of 25+, we’re building sustainable, secure, and scalable financial infrastructure to onboard the next billion users to crypto. Our offerings include liquid staking, automated yield strategies, and crypto-native payment solutions like credit cards, enabling a comprehensive decentralized banking experience. As we continue to scale, we’re actively hiring talented, mission-driven individuals who want to shape the future of finance from the ground up. Learn more at ether.fi.

Position Overview

We’re looking for engineers who want to build & ship, not just fork & integrate. People who get a kick out of solving protocol & blockchain design/implementation problems, hacking on side projects, and building things that actually ship. If you’re the kind of person who reads EIPs for fun, runs the staking validators at home, or has written your own zk circuits just to see how they work, keep reading. This role is onsite 4 days per week at one of our global offices: NYC, Denver, or the Cayman Islands.

What You’ll Work On

You’ll be part of a tight team that ships real things in production — not just a fork of existing protocols, but end-to-end decentralized systems:

Building the future of finance, DeFi, and bringing it to the real world use cases

Designing and deploying Solidity smart contracts for staking, vaults, restaking strategies, and DeFi credit card systems

Building backend systems to automate on-chain operations, secure user flows, and integrate protocol logic

Creating and iterating on real-world crypto utilities like non-custodial credit cards, yield vaults, and validator management tools

Engaging in rigorous testing, code reviews, and documentation to uphold high standards of quality and maintainability

If you\'re curious, check out our products like Ether.fi Stake, Liquid, and Cash — all of them are real, live, and used by thousands of people.

You Might Be a Fit If You

Strong programming & design skill in Solidity

Have strong fundamentals in software engineering & enjoys problem solving

Care about clean & secure smart contract code, and think deeply about edge cases and failure modes

Thrive in fast-moving environments where specs are open-ended and the best idea wins

Have hacked on Blockchain/Smart Contract stuff for fun — maybe you\u2019ve built your own smart contracts, audited protocols, or played around with multiple DeFi protocols, MEV bots, etc.
