Senior Application Support Engineer – Elite Systematic Trading Firm - Prop Trading - Up to £400k TC - WFH

My client, an elite and fast-growing systematic trading firm, is looking for an Application Support Engineer to join a high-impact, London-based team at the cutting edge of global markets.

This is a career-defining opportunity to join an engineering-driven firm where technology is core to every decision. You will provide mission-critical support for low-latency trading systems, automate infrastructure and application processes, and collaborate directly with trading, development, and infrastructure teams.

You will operate in a high-performance environment that values precision, initiative, and continuous innovation.

Key Responsibilities

• Deliver L1/L2 support for proprietary and third-party trading applications across global markets.
• Ensure maximum uptime of latency-sensitive trading platforms, proactively identifying and resolving production issues.
• Automate and enhance support functions using Python, SQL, and monitoring tools like Splunk and Grafana.
• Collaborate with traders, developers, and network engineers to troubleshoot live issues and optimise trading operations.
• Build, maintain, and document proactive alerting systems and health checks for internal and external connectivity (e.g., FIX, REST APIs).
• Drive operational excellence through robust incident management, process improvement, and knowledge-sharing across regions.
• Play a key role in onboarding new trading desks, products, and exchanges—delivering low-latency infrastructure and reliable integration.

Ideal Candidate Profile

• 5+ years’ experience supporting high-performance trading systems in a Linux-heavy environment.
• Strong knowledge of the trade lifecycle in one or more asset classes (e.g., FX, Commodities, Equities).
• Proven expertise in FIX protocol, trading workflows, and exchange connectivity.
• Skilled in scripting for automation (Python, Bash) and familiar with tools like Ansible and Geneos.
• Experience with relational databases (Postgres, Sybase, Oracle) and writing performant SQL queries.
• Knowledge of production-grade monitoring tools (e.g., Grafana, Splunk), alert tuning, and system health validation.
• Understanding of low-latency infrastructure, colocation environments, and performance tuning (CPU affinity, NUMA).
• Strong communicator with a sense of urgency and ownership; capable of leading investigations and mentoring junior staff.

Why Apply?

• Compensation: Highly competitive base salary and performance-based bonus—well above industry benchmarks.
• Career Trajectory: Accelerated progression into senior and team-lead roles.
• Technology Focus: Full exposure to advanced trading tech, hardware-accelerated infrastructure (e.g., FPGA), and bleeding-edge automation.
• Benefits: Comprehensive health coverage, daily meals, pension contributions, and professional development.
• Culture: Join a collaborative and intellectually rigorous environment where engineers directly impact business outcomes.
