🔥 The Opportunity
CoW DAO is fighting MEV and optimizing DeFi trades through:
- CoW Protocol: #1 intent-based DEX aggregator
- MEV Blocker: Protects 100K+ Ethereum users from toxic arbitrage
- CoW AMM: Only AMM that shields LPs from LVR (loss-versus-rebalancing)
We're seeking a blockchain-data-obsessed Data Engineer to build the pipelines that power our fair, MEV-resistant trading ecosystem.
Your work will directly combat extractive MEV and improve execution for billions in monthly volume.
🎯 Key Responsibilities
1. Data Infrastructure
- Design scalable pipelines for on-chain (Ethereum/L2s) + off-chain auction data
- Build real-time monitoring for MEV attacks, liquidity shifts, and auction efficiency
2. Analytics Empowerment
- Create tools that turn raw blockchain data into actionable trading insights
- Support teams with custom dashboards (Dune, Metabase, Looker)
3. Web3 Data Innovation
- Experiment with new data sources (e.g., Flashbots MEV-Share, Eigenlayer)
- Stay ahead of Ethereum upgrades (PBS, EIP-4844) impacting trade routing
🔍 Who We're Looking For
✅ Must-Have Skills:
- Python/SQL mastery: Can transform raw tx data into structured insights
- Blockchain data fluency: Etherscan, Dune, Tenderly, raw RPC nodes
- Pipeline expertise: Dagster/Airflow, data lakes, CI/CD for ETL
✅ Nice-to-Haves:
- MEV/DeFi knowledge: Understands arbitrage, sandwich attacks, LP economics
- Open-source contributions: Web3 data tools (The Graph, Flipside)

- Token ownership: Shape protocol direction with $COW governance
- Lisbon hub: Optional co-working + global team retreats
- Web3 perks: Conference budget, learning stipend, top-tier hardware
Interview Process
- Technical Screen (60min): Design a pipeline to detect sandwich attacks
- Code Review (Async): Optimize a SQL query for LP yield analysis
- Culture Fit (45min): Meet the team—autonomous, impact-driven builders
Stand Out By:
- Analyze our Dune dashboards with 2 improvement suggestions
- Share a project where you processed complex blockchain data
- Explain how you'd track MEV post-PBS (proposer-builder separation)
(CoW DAO celebrates diversity—women, LGBTQ+, and underrepresented builders strongly encouraged to apply.)
