Our technology supports multi-asset liquidity distribution, advanced trading platforms, and systematic trading systems used by financial institutions and professional trading firms around the world.

At Finalto, we combine the scale and stability of a global financial services organisation with the engineering culture and innovation of a fintech company. Our trading and technology teams collaborate closely to build reliable, high-performance systems that support real-time trading and execution.

We are currently expanding our London team and are looking for a Quantitative Developer to implement and maintain systematic trading strategies within our in-house strategy framework.

Role overview

This role focuses on implementing and maintaining systematic trading strategies in production using our internal trading framework.

You will work close to live trading systems, interacting with market data streams, internal APIs, and trading gateways to ensure strategies behave reliably and efficiently in real market conditions.

The position sits at the intersection of quantitative trading and systems engineering. The focus is not pure research, but rather building robust, performant strategy implementations that translate trading logic into reliable production systems.

Please note: this is not a generic backend engineering role – the focus is on implementing trading strategies where small engineering decisions can have real PnL impact.

Responsibilities

• Implement and maintain systematic trading strategies using internal APIs, data streams, and gateway interfaces.
• Translate trading logic into robust production implementations including state management, risk controls, and order lifecycle handling.
• Take ownership of specific strategies and ensure their stability, performance, and reliability in production.
• Improve strategy performance through execution behavior, parameter configuration, monitoring, and system robustness.
• Identify and reduce latency and performance bottlenecks where appropriate.
• Improve efficiency in the data → decision → order execution pipeline.
• Work closely with trading system and infrastructure teams to ensure stable connectivity and data quality.
• Diagnose production issues including data inconsistencies, gateway behavior, or integration problems.
• Contribute to strategy refinement and testing when needed through analysis and implementation-driven experimentation.

What we expect from you

• Strong programming skills in Java and Python (comfortable working with both)
• Experience with object-oriented design and large codebases
• Professional experience with Git-based development workflows
• Solid understanding of concurrency, messaging patterns, and system design
• Familiarity with networking concepts and system integrations
• Experience working with databases and data access patterns
• Strong debugging and problem-solving skills in production environments
• Ability to collaborate effectively with both traders and engineering teams

Preferred Skills

• Experience with low-latency systems or trading infrastructure
• Familiarity with event-driven architectures, pub/sub, or streaming systems
• Experience debugging production trading systems
• Understanding of market microstructure and electronic execution
• Experience building monitoring tools or improving system observability
