We seek a skilled backend developer to build the core infrastructure for a high-frequency, Twitter-driven crypto trading bot. The backend will process real-time Twitter signals, execute leveraged trades on Uniswap via Panoptic, and enforce risk management using Chainlink price feeds. Focus is on scalable, low-latency systems for tweet processing, rule evaluation, trade execution, and stop-loss management.
Twitter Listener Development
- Implement a WebSocket client to stream real-time tweets from monitored accounts/keywords (e.g., using BirdEatsBee API).
- Filter tweets at 0.5-second intervals and forward validated signals to the rule engine.
Rule Engine Implementation
- Design a MySQL schema to store user-defined rules (e.g., follower count thresholds, keywords, leverage).
- Integrate Redis for low-latency rule validation (e.g., checking if a tweet meets criteria like "#BTC" and >10k followers).
Trading Executor
- Integrate Panoptic SDK or Viem to execute leveraged trades on Uniswap v3.
- Implement logic to convert Twitter signals into trade parameters (e.g., 5x long ETH upon valid triggers).
Price Monitoring & Risk Management
- Fetch real-time price data from Chainlink feeds every 0.25 seconds.
- Build stop-loss/take-profit logic with anti-wick confirmation (e.g., 12-second price consistency checks).
- Interact with Gains Network for aggregated market data to minimize liquidation risks.
Infrastructure & Security
- Deploy the Express.js backend on AWS ECS with load balancing and auto-scaling for 99.9% uptime.
- Secure API keys and sensitive data using AWS KMS; audit Panoptic/Chainlink contract interactions.
Optimisation
- Ensure end-to-end latency 1s from Twitter signal to trade execution.
- Optimize Redis pipelines and WebSocket connections for high throughput.
Core Skills
- Experience with Express.js and real-time systems (WebSocket, Socket.io).
- Expertise in **Redis** (caching, pub/sub) and **MySQL** (schema design, optimization).
- Experience integrating **blockchain protocols** (Panoptic, Uniswap, Chainlink) via SDKs/RPC.
Preferred Qualifications
- Familiarity with leveraged trading concepts (liquidation risks, margin calculations).
- Experience with decentralised oracle networks (Chainlink) and aggregated data platforms (Gains Network).
- Understanding of Websocket reconnection strategies and error handling.
