About VNTrading
 

VNTrading is a quantitative trading firm leveraging algorithms and low-latency technologies to provide liquidity across global financial markets. We design and deploy advanced trading strategies that react instantly to market dynamics, using proprietary capital and quantitative research to generate consistent returns.

 

Overview

​

We are seeking a DeFi Trading Engineer to design, build, and optimize systems that power our on-chain and off-chain trading strategies. You will work across the full stack of our crypto trading infrastructure - from smart contracts and on-chain execution to low-latency off-chain systems that integrate with DeFi protocols, exchanges, and data feeds. This is a chance to work on high-impact projects at the intersection of blockchain and algorithmic trading, shaping how our firm interacts with both traditional and crypto markets.

 

Key Responsibilities

​

• Design, implement, and audit secure smart contracts (Solidity, Rust) for on-chain portfolio management and trading logic, optimized for performance, cost efficiency, and security

• Build and maintain high-performance Rust systems that integrate on-chain and off-chain components — powering data feeds, algorithms, and trading pipelines with low latency and high reliability

• Build robust monitoring, simulation, and testing tools to validate system behavior

• Research and evaluate emerging blockchain technologies, identifying opportunities to enhance our trading edge

• Collaborate with quants and engineers to explore new use cases in DeFi and digital asset markets

 

Required Qualifications

​

• 2+ years of experience in backend or full-stack development

• Experience with Solidity or other smart contract languages (e.g., Vyper, Move) and a deep understanding of EVM, gas optimization, and security best practices

• Experience working in Web3, blockchain, or financial services - ideally involving trading infrastructure

• Strong understanding of data structures, algorithms, and design patterns

• Interest in financial markets, digital assets, and algorithmic trading

• Curiosity and eagerness to learn new technologies, with a proactive mindset

 

Preferred Qualifications

 

• Strong grasp of cryptographic principles and blockchain consensus mechanisms

• Understanding of DeFi primitives and market structure — including DEXs, AMMs, MEV, bridges, and lending protocols — and how on-chain liquidity interacts with off-chain systems

• Familiarity with cloud platforms (AWS, GCP, or Azure) for deploying scalable services

• Knowledge of financial markets, market microstructure, or trading concepts

 

We Offer

​

• Base salary range: €4,000 - €8,000 gross per month based on your qualifications, competencies, and professional experience

• Year-end performance-based bonus

• Private health insurance

• Opportunities for professional growth and learning

• Collaborative and dynamic work environment
