Transform Data into Insights

We seek a skilled Backend Developer with expertise in Go or Rust to transform raw on-chain data into actionable insights by decoding smart contract events and implementing pricing logic from decentralized exchanges (DEXs).

This role is ideal for someone who enjoys low-level protocol work, understands DeFi mechanics, and can build robust data pipelines that power real-time pricing engines.

Responsibilities
  • Event Decoders: Develop decoders for major DeFi protocols (e.g., Uniswap, Curve, Balancer) to extract relevant information from on-chain events.
  • Data Extraction: Build and maintain data extractors that convert on-chain events into structured trade data.
  • Pricing Logic: Implement logic to calculate trade prices, including handling swap routing, liquidity pool math, and price inference.
  • Data Ingestion Pipelines: Work closely with data and infra teams to build efficient and scalable data ingestion pipelines.
  • Pricing Models: Optimize performance and accuracy of pricing models (e.g., TWAP, oracle logic, tick-based price resolution).
  • Coding Efficiency: Write clean, well-tested, and efficient backend code in Go or Rust.
Requirements
  • 2–5+ years of backend development experience in Go or Rust.
  • Strong understanding of Ethereum smart contract ABI decoding and event logs.
  • Experience working with DeFi protocols, especially understanding of AMM math: constant product formulas, Uniswap V3 ticks, TWAP / oracle logic.
  • Familiarity with EVM-based chains and Ethereum node infrastructure (e.g., Geth, Erigon, RPC APIs).
  • Experience building data extraction or indexing tools (e.g., subgraphs, custom indexers).
  • Ability to work independently and own complex backend systems from design to deployment.
Nice to Have
  • Experience working directly with blockchain nodes or building custom RPC-based services.
  • Familiarity with price oracles and on-chain data feeds.
  • Exposure to Kubernetes, Docker, and cloud infrastructure (AWS, GCP).
  • Contributions to DeFi or crypto open-source projects.
