Job description

We are looking for an experienced developer to build a
production-grade trading system focused on
low-latency execution and clean, reliable architecture.

This is a technical engineering project, not a guaranteed-profit engagement. Profitability is
not promised and expectations will be defined clearly upfront.

The system will scan markets and execute
triangular, spatial, and statistical arbitrage strategies across multiple exchanges.

### Project Overview


  • Real-time order book ingestion with sub-second latency
  • Smart order routing and execution
  • Ability to manage multiple simultaneous positions
  • Slippage and fee-aware execution
  • Modular, configurable strategy design
### Initial Exchange Scope


  • Binance
  • Coinbase
  • Kraken
The architecture must allow easy addition of new exchanges later.

### Preferred Stack


  • Python or C++ (open to alternatives if you can justify better latency or stability)
  • Clean, well-documented, testable code is mandatory
## Important – How to Apply

**Please answer the following questions directly in your bid.
Bids that do not address these questions will not be considered.**### Screening Questions


  • Have you built
    production-grade trading bots before (not just backtesting tools)?
  • Do you have hands-on experience with
    triangular, spatial, or statistical arbitrage?
  • How do you design systems to achieve
    sub-second latency in real-time trading?
  • What is your approach to
    real-time order book ingestion and fast reaction to price changes?
  • How do you handle
    simultaneous positions, slippage, and fee calculations?
  • Have you integrated with
    Binance, Coinbase, or Kraken APIs before?
  • How do you design exchange connectors so
    new exchanges can be added easily later?
  • What challenges have you faced with
    rate limits or unstable WebSocket feeds, and how did you solve them?
  • Which language would you recommend (
    Python, C++, or other) and why, from a
    latency/stability perspective?
  • How do you keep trading systems
    clean, modular, and well-documented?
  • What
    testing strategy do you use (unit, integration, stress tests)?
  • How would you structure
    multiple arbitrage strategies so they don't interfere with each other?
  • How do you enable or disable strategies via
    configuration, not code changes?
  • What kind of
    real-time monitoring or dashboard would you propose?
  • How do you usually handle
    deployment (Linux VPS, Docker, CI/CD)?
  • How do you monitor
    logs, failures, and system health in production?
  • How would you run a
    24-hour paper-trading validation?
  • Which
    performance metrics would you report?
  • How do you ensure trades are
    opened and closed automatically within predefined thresholds?
  • Have you built
    similar low-latency or arbitrage systems before?
  • Can you share a
    repo, demo, or architecture overview proving that experience?
  • What
    results or benchmarks did your previous systems achieve?
-
  • We're looking for developers who think in terms of
    systems, latency, and correctness, and who can communicate clearly about technical trade offs.
Contract duration of 1 to 3 months. with 40 hours per week.

Mandatory skills:
API, Python, API Integration
