Quantitative Python Developer – Exchange-Based Trading System
Description
Quantitative Python Developer
- Exchange-Based Trading System (Private) Overview
We are developing a private, exchange-based quantitative trading system operating in fast, event-driven markets. The system ingests historical and live data, produces proprietary probability-based scores and entry signals, and executes trades via an exchange API with full order lifecycle and position management.
Although the underlying markets are non-financial, the execution mechanics, order handling, and risk management are directly analogous to financial exchange trading systems.
This is a serious engineering role — not a consumer app, signals product, or website build.
Scope of Work
- Data & Performance Pipeline
Extend and structure historical performance datasets
Implement clean, reproducible data models
Validation and sanity checks
Support ongoing ingestion of new data
(Data sources and feature logic will be disclosed post-NDA)
- Scoring Framework & Entry Gates
Implement a modular scoring framework with configurable parameters
Support multi-component scoring and gating logic
Produce transparent outputs (scores, eligibility flags, reason codes)
Architecture must allow formula changes without refactoring core code
(Scoring formulas and thresholds are proprietary and shared only post-NDA)
- Exchange Execution & Risk
Harden exchange API interaction
Market selection, order placement, monitoring, and reconciliation
Implement cash-out / hedging logic via offsetting orders
Logging, error handling, dry-run and safety controls
- Backtesting & Reporting (Extension)
Backtest entry/exit rules
Basic performance metrics (ROI, drawdown, hit rate)
Exportable results for analysis
