## Job description

## About us

[Ether.fi](http://Ether.fi) is one of the largest crypto companies in the world, with over $10B in assets under management and a team of ~50, almost entirely technical staff. We’ve been profitable since day one and are focused on building real consumer financial applications. We believe the future of finance is true on-chain banking. Our products, Stake, Liquid, and Cash, let users earn yield through DeFi strategies and spend their assets globally through our credit card program. You can view our growth publicly on Dune. As we scale our financial products, maintaining world-class fraud/risk defense is core to protecting our users and the long-term health of our card program.

Position overview We’re hiring a Fraud Lead with a natural scam hunter mindset. You enjoy spotting anomalous patterns, reverse-engineering attack campaigns and building systems that stay one step ahead of sophisticated fraudsters. This is a high-ownership role where you will own the full fraud stack for ether.fi's campaigns, credit card program, fund flows while working extremely closely with our Engineering, CX and compliance teams. Even if you are not a experienced programmer, welcome if you know (or are willing to learn) how to code with the modern AI agents setup.

## What you’ll do

- Own real-time fraud monitoring, alerting, and automated mitigation systems
- Hunt emerging threats: cashback farming, card testing, merchant abuse, friendly fraud, money laundry and malicious behavior inside the [Ether.fi](http://Ether.fi) ecosystem
- Develop and tune advanced fraud rules, behavioral signals, and scoring logic
- Work on internal tools, dashboards, and scripts that make the team dramatically more effective
- Define fraud strategy and operational playbooks that scale with the business
- Active communication with cross-teams and with external business partners to mitigate the fraud risks

## What we are looking for

- You get genuinely excited about weird patterns, scam tactics, and outsmarting attackers
- Exceptional ability to find hidden signals in noisy transaction and behavioral data
- High ownership, low-ego, and ability to drive results in an ambiguous, fast-moving environment

Plus if you have

- Worked at a fintech, neobank or issuer processor
- Exposure to web3/crypto-related fraud patterns
- Exposure to consumer fraud patterns
- Built or scaled early-stage fraud operations teams
- Knowledge of card/payment fraud mechanics (card testing, BIN attacks, friendly fraud, merchant collusion, etc.)

## Perks and benefits

- Competitive salary, performance-based incentives, and token allocation grant
- Opportunity to own fraud defense for multi-billion dollar products
- Health, dental, and vision insurance
- Global team with opportunities for travel across our 3 offices
- 4 weeks work-from-anywhere
- Company events and team-building off-sites

## About Ether.fi

## Company Overview
- **One-liner**: Ether.fi is a leading non-custodial liquid staking protocol and DeFi ecosystem building the rails for decentralized, on-chain banking.
- **Entity Type**: Private (Series A)
- **Headquarters**: George Town, Cayman Islands
- **Founded**: 2022
- **Founders**: Mike Silagadze (CEO) and Rok Kopp

## Core Business
- **Primary Industry**: Decentralized Finance (DeFi) / Liquid Staking / Crypto Financial Services
- **Target Customers**: Crypto-native individual stakers (B2C), institutional node operators, and DeFi users seeking yield and spending products.
- **Mission**: To put users in charge of their wealth—making it easy to save, earn, and spend crypto in a secure, transparent, and non-custodial way.

## Products & Services
- **[Stake (eETH/weETH)](https://www.ether.fi/careers)**: A non-custodial liquid staking protocol. Users stake ETH or stETH and receive eETH (or weETH for DeFi composability), which accrues staking rewards and can be used across DeFi. It is natively re-staked to earn additional yield.
- **[Liquid](https://www.ether.fi/careers)**: Automated strategy vaults that find and optimize yields for users across DeFi protocols.
- **[Cash](https://www.ether.fi/careers)**: A Visa credit card product allowing users to spend and borrow against their crypto assets without selling them. Includes a KYC process and fraud detection.
- **[eBTC](https://www.ether.fi/blog/non-custodial-actively-defended)**: A liquid staking token for Bitcoin, extending the protocol’s non-custodial staking model.
- **[eUSD](https://www.ether.fi/blog/non-custodial-actively-defended)**: A stablecoin product within the ether.fi ecosystem.

## Market Standing
- **Valuation/Market Cap**: Not disclosed (private company).
- **Key Metric**: Over **$10B in assets under management (AUM)** as of June 2026. The company has been **profitable since day one**.
- **Total Funding**: $32.3M raised across 4 rounds (Series A).
- **Notable Investors**: CoinFund, Node Capital, Chapter One (26 institutional investors and 4 angel investors total).
- **Growth Signals**: A team of ~30 people (almost all technical staff) managing over $10B in AUM, demonstrating extreme capital efficiency. The company is actively expanding its product suite into consumer credit cards (Cash) and Bitcoin staking (eBTC), signaling a move from pure DeFi infrastructure to end-user financial applications.

## Competitive Advantages
- **Non-Custodial + Actively Defended**: The protocol is designed so that ether.fi cannot unilaterally move user funds (non-custodial), but it can pause the system and block in-flight attacks to protect users. This is a unique security doctrine that avoids the "decentralization theater" that leaves users drained during exploits.
- **Four-Layer Security Architecture**: Operational security (key/infra hygiene), smart contract bounds (timelocks, rebate caps), crosschain defenses (4-of-4 DVN quorum, per-chain rate limits), and real-time active defense (wired to Hypernative monitoring).
- **Capital Efficiency**: A tiny team (~30) manages a massive $10B+ asset base, indicating highly automated, lean operations and strong technical leverage.
- **Profitability**: Profitable from day one, avoiding the "ponzinomics" and unsustainable token models common in the space.

## Strategic Focus
- **Building Real Consumer Applications**: The company is focused on moving beyond pure DeFi infrastructure into mainstream financial products like the Ether.fi Cash Visa card, bridging the gap between crypto and everyday spending.
- **True On-Chain Banking**: The long-term vision is to offer a full suite of non-custodial financial services (savings, lending, spending) entirely on-chain.
- **Security-First Growth**: The public security doctrine (non-custodial, actively defended) is a core differentiator and a key focus of engineering effort, as outlined in their blog.

## Why Work Here
- **High Impact, Small Team**: With ~30 employees and $10B+ in AUM, every employee has outsized responsibility and influence on the product and protocol.
- **Top Compensation**: Annual performance-based bonuses, option to be paid in ETH, and a share of token allocation.
- **Wellness Benefits**: Unlimited paid time off, one month per year to work fully remotely, plus health, dental, and vision coverage.
- **In-Office Collaboration**: The company emphasizes in-person work (79% on-site, 16% hybrid) with offices in New York, Denver, Grand Cayman, and Dubai. They believe face-to-face interaction drives success.
- **Culture & Events**: Frequent company off-site retreats (e.g., Cayman Islands, Lisbon) and attendance at top crypto events.
- **Engineering Culture**: A builder-first environment with a focus on security, smart contract engineering, and real-time fraud/scam hunting. The interview process includes a skills-based interview and a final meeting with the CEO.
- **Guiding Principles**: Decentralization is a primary objective, sustainable revenue model, and "never compromise on ethics."
