Backend Developer Position

We are seeking an experienced backend developer to contribute to our team.

This role is ideal for someone who enjoys low-level protocol work and understands DeFi mechanics.

The successful candidate will be responsible for developing event decoders, building data extractors, implementing logic to calculate trade prices, and working closely with data and infra teams.

Key Responsibilities:

  • Develop 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).

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.
