Careers & Services
Quantitative Developer
Singapore HashKey Capital
Key Responsibilities
- Turn research models and prototypes into production Rust — quoting, hedging and inventory logic — including the tests and edge cases a prototype skips
- Build and maintain the shared backtesting and simulation framework, with fill logic that reflects queue position, latency, fees and market impact
- Develop signal and feature pipelines that compute consistently offline and online, so a signal means the same thing in research as in production
- Build the P&L attribution and execution-quality tooling the trading team relies on, including markout and adverse-selection analysis
- Build and maintain the configuration and parameter systems that make changes to live strategies safe, reviewable and reversible
- Diagnose unexpected strategy behavior — reproducing it and narrowing it to model, parameters, market regime or venue
- Improve research and trading velocity by removing the manual steps that slow the team down
- Actively leverage AI coding as a core part of the development workflow to accelerate delivery and improve code quality
Qualifications
- Bachelor's or Master's degree in Computer Science, Mathematics, Physics, Statistics, or a related STEM field
- Five years of relevant experience is preferred — strong graduates are in scope, and we expect to teach the domain
- Strong programming ability in Rust, or in C++, Go, or Java with the demonstrated ability to pick up Rust quickly
- Proficiency in Python for research and analysis, including the data stack (pandas or polars, numpy)
- A working grounding in probability, statistics and time-series analysis — enough to assess whether a backtest result is robust
- Genuine curiosity about market microstructure: order book dynamics, fill quality and execution cost
- Attention to correctness and failure cases, including the instinct to catch a wrong number that does not raise an error
- A track record of finishing work independently — production experience, open-source contributions, or competitive programming results — and comfort with autonomy and rapid iteration in a small team
Preferred
- Experience supporting a trading desk, research team or market-making book as an engineer, in any asset class
- Hands-on crypto trading experience, professional or personal
- Familiarity with perpetual funding, basis and cross-venue pricing
- Familiarity with DEX mechanics — AMM and concentrated-liquidity design, EVM, MEV
- Experience building or maintaining backtesting or simulation frameworks used by others
