Senior C#/.NET Engineer (Trading System) - Part-time - Overlap PST

Project Overview

The client has a partially built automated futures trading system in C#/.NET on Quantower.
Core components—wavelets, indicators, AI framework, rule-based strategies, execution engine, and risk module—already exist, but the system is not yet operational.
Your role is to finish, integrate, stabilize, and deliver a fully working trading bot.

Key Responsibilities

• Implement AI model persistence (save/load trained models)
• Build the AI training pipeline (historical data → preprocess → train → validate → export)
• Integrate AI + wavelets + rule-based strategies into a unified strategy
• Make the system run end-to-end inside Quantower
• Add backtesting and performance verification
• Implement full .NET logging (signals, decisions, orders, errors)
• Move hard-coded values into appsettings.json
• Improve stability: multithreading, race conditions, error handling
• Validate signal quality and ensure logical, consistent outputs
• Document the system and show the client how to operate it

Required Experience

• Expert C#/.NET
• Real automated trading systems experience
• Multithreaded, real-time execution
• ML model inference + persistence (ML.NET or similar)
• Strong preference for Quantower experience; NinjaTrader/Sierra/MetaTrader also helpful
• Ability to work with and extend an existing codebase efficiently
• Clear communication and reliability (weekly syncs, accountable delivery)

Additional Notes

• This is completion work, not a new build. The existing architecture should remain intact.
• The hired developer is expected to explain workflows and guide a non-technical founder
• The client is looking for a long-term collaborator for ongoing maintenance and updates after initial completion.
