Backend Engineer – DeFi Protocol (Remote)
Full-time • Remote

Role Summary

Exchequer Finance seeks a Remote Backend Engineer to build real‑time Python services that integrate with EVM networks, power auctions, and liquidity workflows, and serve low‑latency APIs for our React/Apollo + wagmi/viem frontend clients.

About Exchequer Finance

Exchequer Finance is a US-based DeFi protocol. We build permissionless infrastructure that enables projects to achieve sustainable DEX liquidity through structured principal-protection primitives and bond-like lifecycle mechanics, implemented as smart contracts and backend services that maintain protocol state. Work closely with the founders to ship core systems that redeem crypto's promise by reducing reliance on extractive intermediaries and centralized market makers.

Our Stack

  • Backend: Python with FastAPI for APIs and async I/O, typed validation, and production serving via Uvicorn/Gunicorn
  • Web3: web3.py for Ethereum/L2 JSON‑RPC, contract calls, event/log decoding, and reorg‑aware processing
  • Data and streaming: PostgreSQL (primary), Redis for caching/queues, Kafka for event streaming and replayable pipelines
  • Front-end context: React 18, Apollo Client; wallet/chain integration via wagmi, Viem, and RainbowKit for seamless integration with backend APIs
  • Cloud & DevOps: Google Cloud; Containers: Docker; CI/CD: GitHub Actions; Monitoring and logging in place

Responsibilities

  • Build and operate Python services and APIs for auctions, DEX liquidity orchestration, and bond‑like lifecycle management using FastAPI and robust validation/testing
  • Integrate with Ethereum/L2s via web3.py to subscribe to logs/events, process transactions, and maintain protocol state with idempotent, reorg‑safe workflows
  • Develop real‑time pipelines and indexers using Kafka and Redis to power fast queries, backfills, and replayable event processing for on‑chain data
  • Design efficient database schemas and caching strategies using PostgreSQL and Redis to support high-frequency DeFi operations and low-latency APIs
  • Implement observability, alerting, retries, and graceful failure/recovery patterns across services for reliable production operations

Requirements

  • 7+ years building production backend systems. Python with strong async I/O, testing, performance, and profiling experience
  • Proficiency with FastAPI (or similar) and a deep understanding of HTTP, JSON‑RPC, concurrency/async patterns, and error handling for API services
  • Hands‑on blockchain integration with web3.py: ABIs, event filtering, transaction lifecycle, RPC nuances, and reorg handling across Ethereum/L2s
  • Database expertise with PostgreSQL and operational experience with Redis and Kafka for event‑driven architectures and streaming workflows
  • Cross‑team collaboration with frontend engineers using Apollo Client and wagmi/viem to shape API contracts and event feeds that fit client usage patterns
  • Strong Linux fundamentals, networking (HTTP/TLS), observability, and performance profiling
  • Familiarity with service observability in production environments
  • The time zone must have a significant overlap with Eastern Time (New York City)

Nice to Have

  • Experience building custom EVM indexers, snapshot/catch‑up strategies, and replay tools for chain data pipelines
  • Familiarity with RPC provider strategies and cost/latency monitoring for Ethereum JSON‑RPC workloads in production environments
  • Exposure to CI/CD, containers, and cloud operations for Python microservices and streaming systems in production contexts

Benefits

  • 20 paid days off per year (vacation, sick leave, and your local public holidays)
  • Annual learning & development budget for courses, books, and conferences
  • Paid attendance at relevant crypto / DeFi events
  • Contract: B2B / 1099 (invoicing in USD, paid monthly)
  • Work directly with a U.S.-based founding team building production DeFi infrastructure
  • Grow your expertise in crypto and decentralized finance while shipping real-world systems

Recruitment Process

  • Use the chat widget below to connect with our team and share your resume and a short note with relevant Python/web3.py projects, API/streaming systems operated in production, and any EVM indexing or reorg‑handling work
  • Links to repos or write‑ups are welcome
  • 30-minute technical interview
  • Initial 3-month probationary period (standard for all new hires)
