Senior Fullstack DeFi Engineer
$ 75,000 - $ 100,000
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
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.
