About this Role:

We're seeking a seasoned backend engineer to lead the development of event decoders for major DeFi protocols. You'll play a pivotal role in transforming raw on-chain data into actionable insights by decoding smart contract events and implementing pricing logic from decentralized exchanges (DEXs).

This position 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.

Key Responsibilities:

  • Own the development of event decoders for major DeFi protocols (e.g., Uniswap, Curve, Balancer).
  • Build and maintain data extractors that convert on-chain events into structured trade data.
  • Implement logic to calculate trade prices, including handling swap routing, liquidity pool math, and price inference.
  • Collaborate with data and infra teams to build efficient and scalable data ingestion pipelines.
  • Optimize performance and accuracy of pricing models (e.g., TWAP, oracle logic, tick-based price resolution).
  • Write clean, well-tested, and efficient backend code in Go or Rust.

Required Skills and Qualifications:

  • 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: x * y = k
  • 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.

Benefits:

  • Build the core infrastructure that powers real-time pricing and analytics in DeFi.
  • Tackle complex and novel engineering problems in the blockchain data space.
  • Work in a fast-paced, remote-first environment with a highly technical team.
