Web3 Developer

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.
