MARGO is hiring an experienced ITS Application Services Engineer to join a Global Markets technology team. You'll support and enhance the low-latency infrastructure powering electronic trading systems - ensuring connectivity, performance, and reliability across FX and Fixed Income platforms.
Location: Hybrid, Central London
Your mission:
Deliver and maintain a world-class, low-latency trading environment - managing messaging middleware, network connectivity, observability tooling, and capacity planning to meet front-office demands.
What you'll do:
Connectivity & Monitoring:
Deploy and support global market connectivity (Solace/Tibco, multicast, TCP/IP) across 30+ sites. Implement SRE principles: automated health checks, alerting, SLIs/SLOs, and capacity forecasts.
Incident & Performance Management:
Lead deep-dive post-incident analyses (e.g., market events), using packet captures (Wireshark/tcpdump/Corvil). Maintain dashboards (Geneos, Prometheus, Grafana) for proactive issue detection.
Automation & Resiliency:
Build scripts (Python/Bash/PowerShell) and IaC for self-healing systems and reduced manual toil. Execute lab-based testing and benchmarking for new connectivity solutions.
Collaboration & Delivery:
Partner with global network, platform, and development teams to onboard applications and define standards. Own change-management processes, operational handoffs, and documentation (topologies, runbooks).
Technical fit – what we're looking for:
Strong background in low-latency networking: TCP/IP, multicast, traffic shaping, performance tuning. Proven experience with messaging middleware (Solace, 29West, Tibco, LBM) in performance-sensitive environments. Hands-on packet analysis using Wireshark, tcpdump, Corvil (custom decoder skills a bonus). Scripting/automation with Python, Bash, or PowerShell. Familiarity with observability platforms (ITRS Geneos, Prometheus, Grafana). Experience supporting real-time trading applications, feed handlers, matching engines. Excellent communication—able to translate technical metrics into business insights.
Nice to have:
Exposure to FIX/market-data protocols and order-routing architectures. Hands-on use of CI/CD pipelines and IaC tools (Terraform, Ansible). Experience with capacity planning and error-budget management.
Tech stack & skills:
Middleware: Solace/Tibco/LBM
Networking: TCP/IP, multicast, BGP/OSPF, traffic shaping
Monitoring: ITRS Geneos, Prometheus, Grafana, Corvil
Automation: Python, Bash, PowerShell, IaC
Systems: Linux (Red Hat/CentOS), hybrid cloud infrastructure
