About the role
As Network Architecture Lead you will have ultimate architectural oversight and long-term design direction for QRTs trading and enterprise networks. Working closely with the global network team, you will help define and document the long-term design direction for QRTs trading and enterprise network globally. Key to the role will be collaborating with the team to defining practical standards and ensuring designs are scalable, supportable, instrumented and aligned with business requirements. Success in this role means establishing a clear, network-wide architectural direction, with teams consistently applying agreed and documented standards rather than developing isolated or site-specific solutions.

Design and maintain documentation for the current-state, target-state and transition plans for QRT’s global trading and enterprise networks.
•
Define architecture standards and reference designs in cooperation with the network teams.
•
Review significant designs for scalability, resilience, latency, simplicity and operational support.
•
Document design decisions, dependencies, monitoring requirements and expected operating models.
•
Define instrumentation standards covering telemetry, monitoring, logging, alerting and dashboards.
•
Identify and track architectural risks, technical debt and gaps between current and target states.
•
Apply lessons from project delivery, operational experience and incidents to strengthen future designs.
•
Build alignment across engineering and business stakeholders, ensuring teams adopt consistent and documented design patterns.
