Engineering Squad Lead – Backend (Exposure Platform)
London (Hybrid)
The company
A global fintech firm operating at scale, delivering trading platforms used by hundreds of thousands of clients worldwide. The business is continuing to invest heavily in its core trading infrastructure, with a strong focus on improving delivery speed, system maturity, and overall engineering effectiveness.
The role
This is a leadership opportunity within a business-critical platform that sits at the heart of trading operations, responsible for real-time exposure, risk management, and hedging across client positions. The system processes high volumes of trading data and directly impacts trading performance and decision-making.
You will lead a backend engineering squad working on low-latency C++ systems, while helping to modernise a complex legacy platform. A key focus will be improving release cadence and delivery maturity, alongside driving architectural improvements without disrupting existing production systems.
What you will do
- Define and drive the technical vision for the team, aligning with both stakeholder needs and long-term system evolution
- Lead and develop a high-performing engineering team, encouraging autonomy and ownership
- Work closely with trading desks, quants, and risk teams to deliver business-critical functionality
- Improve delivery processes, release cadence, and system reliability
- Lead the modernisation of legacy components, balancing innovation with operational stability
- Remain hands-on where needed, contributing to C++ and Python code in production
What you will need
- Strong C++ experience within low-latency or real-time systems
- Exposure to Python (or willingness to work with it)
- Experience working on complex, business-critical platforms (ideally within trading or financial systems)
- Proven ability to lead teams and influence across stakeholders
- Experience working with legacy systems and improving them pragmatically (rather than full rebuilds)
- Strong communication skills and commercial awareness
Why consider this
- Work on systems that directly impact trading performance and business outcomes
- Opportunity to lead both technical direction and team evolution
- High visibility role with significant stakeholder interaction
- Chance to modernise and improve a large-scale, low-latency platform
Summary
A leadership role combining low-latency engineering, stakeholder engagement, and pragmatic system modernisation within a high-impact trading environment.
