Who we’re looking for

We are hiring a Senior Blockchain Backend Engineer in 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

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.
