Company Profile

We're building an AI-native quantitative trading platform — not a toy backtester, not another indicator factory. Our goal is to let traders and researchers create full-stack algos end-to-end: alpha generation, backtesting, optimization, and execution — using raw data and AI-assisted tooling.

This role sits between quant research, systems engineering, and applied AI.

Job Description

What You'll Do

You will help build internal tools and infrastructure that power systematic trading and AI-assisted research.

Core Responsibilities

  • Build quant research tools using Python/C++ (data pipelines, factor engines, strategy evaluation).
  • Develop AI-assisted workflows (LLM-driven feature generation, strategy templating, analysis summaries).
  • Work with raw market data (intraday OHLCV, tick, derived features).

  • Integrate AI into:

  • Alpha discovery

  • Pattern detection
  • Strategy diagnostics
  • Help design modular systems that allow fast experimentation (not hard-coded strategies).
  • Write clean, testable, production-grade research code.
  • Collaborate closely with senior quants and system architects.

This is a build-first role. You will ship tools weekly, not sit in meetings.

What You Need (Non-Negotiable)

  • Strong Python fundamentals (pandas, numpy, data structures).
  • Solid software engineering mindset (modular code, version control, debugging).
  • Comfort working with time-series data.
  • Familiarity with backtesting concepts (look-ahead bias, slippage, overfitting).
  • Curiosity about how AI can augment research, not replace thinking.
  • Ability to read vague problem statements and turn them into working systems.

Nice to Have (But Not Required)

  • C++ or Rust experience.

  • Experience with:

  • Market microstructure

  • Systematic trading strategies
  • Intraday / high-frequency data
  • Prior work using LLM APIs (OpenAI, Anthropic, etc.).
  • Familiarity with ClickHouse / PostgreSQL / Parquet.
  • Experience building internal tools rather than end-user apps.

What This Role Is NOT

    • Not a signal-copying role
    • Not manual trading
    • Not a "prompt engineer" job
    • Not a pure research or pure ML role

This is systems + quant + applied AI.

What You'll Learn (Fast)

  • How real quant systems are built (not academic versions).
  • How to structure research for scale and reuse.
  • How AI actually helps discovery (and where it doesn't).
  • How profitable strategies are engineered, tested, and killed.

If you perform, your scope will expand rapidly.

Compensation

  • Competitive junior-level base
  • Performance-based bonuses
  • Meaningful upside as responsibility grows

Who This Is Perfect For

  • Strong junior engineer who wants exposure to real trading systems
  • Someone bored of CRUD apps and dashboard work
  • A builder who learns fast and asks hard questions

If you're looking for hand-holding, this is not it. If you want to build the engine, not click buttons, this fits.
