About the Role

Our team is seeking a skilled Backend Developer with experience in Go or Rust to help transform raw on-chain data into actionable insights. You'll play a key role in 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.

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.
  • Work closely 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.

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: 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.

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.

Why Join Us?

  • 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.
  • Competitive compensation and potential for token/equity upside.
