Requirements
Must:
We are seeking candidates with a strong background in low latency network engineering, including TCP/IP, multicast, traffic shaping, and performance analysis. You should have proven experience with packet capture and analysis tools (such as Wireshark, tcpdump, Corvil/PICO), and the ability to build custom decoders is highly advantageous. Familiarity with SRE tools and practices, including infrastructure as code (IaC), CI/CD pipelines, error budgets, and reliability-focused SLIs/SLOs is important. Experience in supporting real-time trading applications, including feed handlers, matching engines, and algo trading platforms is necessary. A strong working knowledge of messaging middleware (e.g., Solace, 29West, Tibco, LBM) in performance-sensitive environments is required. You should also be proficient in scripting and automation using Python, Bash, or PowerShell, and have a good understanding of FIX, market data, and order routing protocols in a trading environment. Exposure to observability platforms such as ITRS Geneos, Prometheus, Grafana, or custom telemetry stacks will be beneficial. Comfort working across Linux systems, hybrid infrastructure, and global production environments is essential. Excellent communication and reporting skills, with the ability to translate technical data into actionable business insights, are also required.

As an Application Services Engineer, you will be part of a team responsible for supporting and managing the infrastructure that supports our Bank's electronic business. You will work closely with core infrastructure teams, development, and the business to respond to requests and fault reports, often resolving issues quickly and under pressure, including out-of-hours support when necessary. Your key responsibilities will include delivering and supporting low latency connectivity and monitoring solutions for the Global Markets business, applying SRE principles to improve availability, latency, performance, and capacity planning across trading infrastructure. You will collaborate with network and platform engineers to design reliable, self-healing systems and reduce manual intervention through automation. Additionally, you will own and execute the Global Markets connectivity roadmap, partner with business stakeholders to ensure that our infrastructure and observability tooling meets evolving trading requirements, and monitor and manage the capacity and performance of global connectivity systems.
Description
You will conduct deep-dive post-incident analysis and forensic reviews during high-impact market events, utilizing packet analysis to identify systemic improvements. Your role will involve developing and maintaining automated alerting, health checks, and dashboards to support proactive detection of issues and system degradation. You will lead lab-based testing and benchmarking initiatives for new connectivity solutions, ensuring readiness for production deployment. Producing operational and performance KPIs, SLO/SLI metrics, and executive summaries to support senior decision-making will be part of your duties. We champion continuous improvement and innovation, driving technology adoption in monitoring, resiliency, and incident response tooling.
