We are hiring a Senior Blockchain Backend Engineer in the Lambda team to build and operate backend services for DeFi / on-chain products (positions, balances, yield, PnL, NAV, and partner-facing integrations). The role is hands-on, with ownership from design to production reliability.

About Lambda: Lambda is the DeFi Intelligence Platform. We provide a single source of truth for on-chain financial data, enabling investors and institutions to:

  • Track token balances and DeFi positions across multiple chains
  • Analyze historical and real-time rewards
  • Accurately calculate PnL and uncover hidden costs (e.g., slippage, rebalancing, fees)
  • Compare strategies and pools across protocols with confidence

Our mission is to make crypto data transparent, reliable, and actionable, reducing the time to generate accurate performance reports from weeks to just a few hours. We’re a fast-moving startup with a strong technical culture, building the backbone of crypto data infrastructure.

Tech stack:

  • Core backend & data platform
  • Python services and tooling
  • Datastores / analytics: Postgres, ClickHouse, Redis
  • Blockchain / DeFi domain
  • EVM protocol integrations and on-chain balance / position logic
  • Infrastructure: GCP, Kubernetes (GKE), Docker, CI/CD with GitHub

Key Responsibilities:

  • Build and maintain protocol adapters and position mapping logic (lending, staking, LPs, vaults, and other protocol-specific position types).
  • System design of service to run calculations on-top of smart contracts.
  • Optimize RPC requests and smart contract operations.
  • Design and implement on-chain data components for fetching on-chain data.
  • Debug and resolve production issues related to RPC/providers and data correctness; implement practical mitigation and resilience mechanisms.
  • Improve observability: logging, metrics, alerting, and runbooks for owned components.

What we expect:

  • 5+ years backend engineering experience, including production ownership.
  • 2+ years blockchain experience.
  • Strong understanding of blockchain data and DeFi position mechanics (or proven ability to learn quickly and ship safely).
  • Smart contract literacy (reading Solidity, understanding on-chain storage/events, debugging contract interactions).
  • Experience designing systems that are robust to imperfect data sources and provider instability.
  • Clear communication and strong ownership.
  • You are comfortable with performance work (latency, throughput) and debugging across services.

Nice to have:

  • Experience with data practices for on-chain datasets.

At P2P.org we have a team of experts with their own unique approach and ownership culture. Together we gain experience and make dreams come true!

Fully remote, full-time contractor (Indefinite-term Consultancy Agreement), competitive salary level in $ (we can also pay in crypto), paid vacation and sick leave, well-being program, mental health care program, compensation for education, including foreign language & professional growth courses, equipment & co-working reimbursement program, overseas conferences, community immersion.
