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
- 3+ years’ experience supporting high-performance trading systems in a Python and 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.
