## Description

### ABOUT RAVEN

Raven is a proprietary crypto market-making and high-frequency trading firm. We trade spot, perpetuals, and prediction markets with dedicated low-latency infrastructure across eight major trading regions.  
  
We hire competitive individuals and natural problem solvers with a record of ranking at something hard, whether competitive programming, games, or mathematics, who treat an unfamiliar problem as a challenge rather than an obstacle. We can teach markets; we cannot teach drive.  
  
We build our own stack end to end, from connectivity and pricing through execution, monitoring, and research data.

### THE ROLE

We are looking for developers and traders interested in building systems for on-chain markets. You will work on strategies and infrastructure interacting directly with decentralized protocols, where execution, timing, and market structure are critical.

-   developing trading systems interacting with DeFi protocols
-   designing and implementing on-chain execution strategies
-   researching opportunities across different chains and protocols
-   building tools and infrastructure for on-chain trading
-   optimizing execution, latency, and capital efficiency
-   monitoring and improving live trading performance

### **WHO WE'RE LOOKING FOR**

-   strong programming skills (Rust, Python, Go, or similar)
-   understanding of blockchain fundamentals and smart contracts
-   strong analytical and problem-solving skills
-   experience working in Linux environments
-   interest in DeFi markets and trading systems

‍

**Nice to have**

-   experience interacting with smart contracts or Web3 tooling
-   familiarity with on-chain trading, MEV, or protocol design

‍

**Why join Raven**

-   work on systems operating in real on-chain markets
-   collaborate directly with traders and engineers
-   explore new and rapidly evolving market structures
-   see your work directly impact trading performance

### LOGISTICS

\- Sofia (Bulgaria) or Milan (Italy), with no preference between them. Whichever city the right person is in   
\- In office, not remote  
\- Crypto trades around the clock. You will share a sane on-call rotation with the team that owns these systems
