A world-leading investment bank is hiring a Python Engineer to join its Front Office FX Options Technology team - one of the most business-critical engineering environments in the firm.
You’ll sit at the heart of the trading floor, partnering directly with traders, quants, and sales to build low-latency, high-performance trading systems that influence real-time market decisions. If you’re motivated by solving complex problems at scale, building systems where microseconds matter, and seeing your code directly drive P&L - this is that opportunity.

- Architect and build real-time pricing, eTrading, and market-making systems used globally
- Design and optimise latency-sensitive trading algorithms and analytics pipelines
- Develop high-throughput data platforms for market data ingestion and predictive modelling
- Partner directly with front-office stakeholders to translate trading strategies into production systems
- Improve market connectivity, execution performance, and system resilience
- Drive engineering excellence across distributed systems, scalability, and performance tuning
What We’re Looking For
- Strong Python engineering expertise with a focus on performance and scalability
- Deep understanding of algorithms, data structures, and system design
- Solid knowledge of data engineering concepts (SQL/NoSQL, pipelines, large datasets)
- Track record of delivering production-grade systems in fast-paced environments
- Ability to operate close to the business with strong communication and ownership
- Background in financial markets, trading systems, or FX is beneficial - but strong engineers from other domains are encouraged
