Quantitative Trader Full Time

Company Description

At Finalto, we are a global liquidity provider and trading technology partner, serving institutional clients across multiple asset classes and markets.

We combine the scale and stability of an established financial services organization with the innovation and engineering culture of a fintech company. With regulated entities across the UK, EU, Asia, and Australia, and a strong global presence, we deliver advanced trading solutions, liquidity, and risk management infrastructure to our clients.

As part of our continued growth, we are expanding our London team and are looking for a Quant Trader (Options) to join us.

Role Description

This role sits at the core of the trading desk and is responsible for the day-to-day management of an options book, with full ownership of risk and PnL.

You will play a key role in ensuring the book operates in a controlled, systematic, and commercially competitive way. This is a hands-on position focused on running a live book — requiring continuous monitoring, decision-making, and adjustment based on market conditions and observed performance.

This is not a pure research role – it requires active ownership, monitoring and real-time decision-making in a live trading environment.

Responsibilities

• Own and manage the options book within defined risk limits

• Take full responsibility for desk PnL and its key drivers

• Monitor and manage Greek exposures (delta, gamma, vega, etc.)

• Execute and continuously refine hedging strategies to balance risk and cost

• Ensure risk is effectively controlled across changing market conditions

• Analyse and break down PnL into key components (carry, volatility, hedging costs, slippage)

• Identify, explain, and respond to drawdowns and unexpected behaviour

• Develop a clear understanding of performance drivers versus noise

• Configure and adjust the internal pricing engine to ensure quotes remain competitive while protecting margins

• Continuously refine pricing based on market conditions and flow quality

• Oversee day-to-day desk operations, including product setup (e.g. new expiries, instruments)

• Ensure consistency and reliability in how products are managed

• Collaborate closely with quant and engineering teams to improve monitoring, observability, PnL traceability, and diagnostic capabilities

What we expect from you

• Strong understanding of options pricing and behaviour

• Practical experience managing risk through Greeks (delta, gamma, vega, etc.)

• Proven ability to manage and interpret PnL in a trading environment

• Strong Python skills for data analysis (e.g. Jupyter notebooks)

• Experience working with tick-level data

• Solid experience with databases and data analysis

• Ability to operate in a live trading environment and make decisions under uncertainty

• Strong ownership mindset and accountability for outcomes

• Clear communication skills, especially when explaining performance, risk, or drawdowns

Preferred skills

• Experience working with or configuring pricing engines

• Familiarity with volatility surfaces and calibration challenges

• Understanding of market microstructure and execution impact

• Experience collaborating closely with engineering teams on trading tools

If you are a hands-on trading professional who enjoys working close to real risk, understands how to manage and explain PnL, and thrives in a fast-moving environment — we would love to hear from you.
