- Use Python for model prototyping, data analysis, signal investigation and backtesting activity
- Develop and improve pricing skew, spread and liquidity optimisation logic
- Design and implement automated hedging strategies, taking into account execution risk, liquidity and market impact
- Support pricing system deployment across distributed, multi-region architecture with a focus on uptime and consistency
- Analyse client trading behaviour, including flow quality, decay and pricing performance, to support more effective pricing decisions
- Contribute to the ongoing evolution of tools and systems used in a live institutional trading environment
REQUIRED - SKILLS/EXPERIENCE:
- Strong Java development experience, ideally 5+ years
- Deep understanding of object-oriented design, concurrency, and high-performance distributed systems
- Proficient in Python; Including use of libraries such as NumPy, SciPy and Pandas for quantitative analysis and prototyping
- Proven experience applying numerical optimisation techniques and/or machine learning methods to pricing, trading or market-related problems
- Prior experience in client pricing, electronic trading, or a closely related quantitative trading environment
- Exposure to liquid markets such as FX, equities, ETFs or crypto
- Strong academic background in a quantitative discipline such as Mathematics, Physics or Quantitative Finance
- Ability to operate effectively in a role that bridges quantitative modelling and production engineering
DESIRABLE - SKILLS/EXPERIENCE:
- Familiarity with low-latency system optimisation, such as GC tuning or tools/frameworks used in high-performance messaging environments
- Understanding of derivatives pricing and risk management, particularly across products such as futures, forwards, NDFs and CFDs
