Job Description

🌍 About Our Client

 

Our client is building the next-generation digital asset management platform — bridging DeFi and TradFi with professional-grade tools, advanced risk models, and high-performance strategy engines.

Backed by leading investors and committed to delivering audited, production-grade products, they move fast, build with intent, and aim to become the definitive platform for digital asset strategies.

👤 About the Role 

They’re looking for a Senior Python / DeFi Engineer to join their small, high-performing team. This is a backend-focused role with opportunities to contribute across the stack. You’ll work closely with product and strategy leads to design, model, and ship real DeFi strategies — not prototypes or experiments, but robust, production-ready tools.

This role is ideal for someone with deep Python skills and real-world experience building in DeFi environments — someone who understands the protocols, the mechanics, and the risks, and is excited to build the future of asset management.


✅ What You’ll Bring
 

  • 5+ years of Python experience in backend or data-heavy environments

  • 2+ years of hands-on DeFi experience — building or maintaining real strategies/products

  • Strong understanding of DeFi market structure: AMMs, order books, lending protocols

  • Familiarity with key protocols such as Aave, Spark, Pendle, etc.

  • Experience working with document-oriented databases (e.g. MongoDB)

  • Proficient in data analysis: Pandas, NumPy, time-series and performance modeling

  • Analytical mindset — comfortable modeling, graphing, and evaluating strategy behavior

  • Proactive, self-driven, and capable of working independently

  • Excellent written and verbal communication skills

  • 2+ years of frontend experience with: React (TypeScript), TailwindCSS, Vite, Zustand


đź’ˇ Nice to Have
 

  • Ability to read/test Solidity smart contracts

  • Experience with DeFi strategy engines, portfolio/risk tools, or simulations

  • Background in quantitative finance, mathematics, or data science

  • Familiarity with Web3 SDKs and infra (The Graph, Infura, Alchemy, etc.)


🔧 What You’ll Do
 

  • Build and iterate on strategy and risk products from MVP to production

  • Model and test leveraged yield, LP, and lending strategies across major DeFi protocols

  • Analyze and monitor strategy performance (real-time and historical)

  • Work backend-first, but contribute to frontend when needed

  • Collaborate with product and strategy teams to move quickly from concept to implementation

  • Create internal tools for strategy evaluation, simulations, and risk modeling


đź§° Tech Stack

  • Backend: Python, MongoDB, PostgreSQL, Redis

  • Frontend: React + TypeScript, TailwindCSS, Vite, Zustand

  • Blockchain: Web3, ethers.js, wagmi

  • Data: Pandas, NumPy, matplotlib, Plotly

 

👉 Why Apply? 

If you’re a technically strong backend engineer with a DeFi-native mindset and want to work on real strategies — not pitch decks or sandbox experiments — this is a chance to shape the next era of digital asset management from the ground up.
