Blockchain 121 is hiring a

Quant (Maker-Side, HFT/Crypto)

We've partnered with a company that is aiming to create real-time markets for trading trends, using data from media platforms. They aim to revolutionise how trends are discovered, traded, and monetised in the digital age. It positions itself as a solution to capture and trade the "value of attention".

We are seeking a highly technical and independent Quant with a deep understanding of market-making systems, either from a traditional HFT background or crypto-native trading environment. This role is for someone who thinks from the maker side—designing, running, and optimizing trading systems, not just predicting prices.

What You’ll Do

• Design, backtest, and optimise market-making strategies across centralized or decentralized markets
• Implement risk-aware systems including inventory management, optimal execution, and latency-aware logic
• Analyse order book dynamics and build robust execution models
• (If crypto-focused) Research and exploit inefficiencies in perpetual DEXes
• (Nice to have) Apply MEV techniques or experience with on-chain search strategies to improve execution or PnL
• Collaborate with engineers to deploy strategies and monitor live performance

What We’re Looking For

• Proven experience building market-making or execution strategies in HFT or crypto
• Strong understanding of stochastic control, queuing theory, and risk frameworks in MM
• Comfortable working with noisy, high-frequency data and optimizing for latency
• (For crypto side) Deep understanding of DeFi mechanics, especially perpetuals and DEX design
• Bonus: Experience with MEV, on-chain research, or protocol-level optimization
• Programming in Python, C++, or Rust; familiarity with data pipelines and simulation engines
