Job Description:
Cloud & Hybrid Network Design
- Define and maintain scalable network architectures across public cloud platforms, covering address design, segmentation, routing strategy, and regional connectivity.
- Build and evolve secure connectivity between cloud environments and external locations such as offices, exchanges, and third-party facilities using private circuits, SD-WAN, and encrypted tunnels.
- Establish standardized network blueprints for large-scale environments spanning multiple accounts or subscriptions, with strong isolation and governance.
Availability, Performance & Scalability
- Architect networks for continuous availability, including multi-region designs, active-active patterns, and automated failover.
- Tune network paths to support low-latency and throughput-sensitive systems while managing cost and operational complexity.
- Lead capacity forecasting, traffic optimization, and performance visibility across hybrid estates.
Delivery & Automation
- Personally drive implementation of network infrastructure using infrastructure-as-code and automated deployment pipelines.
- Promote automation and repeatability to minimize manual changes and reduce operational risk.
- Integrate network metrics, logs, and telemetry into central monitoring systems to enable early detection and rapid diagnosis.
Secure Architecture
- Apply zero-trust principles within network designs, including fine-grained segmentation, private service access, and controlled ingress/egress.
- Work closely with security stakeholders to implement defensive controls such as DDoS protection, access enforcement, and policy-driven routing.
- Ensure all designs align with internal governance standards and external regulatory or audit requirements.
Business & Application Enablement
- Partner with application, data, and trading-oriented teams to translate performance and reliability requirements into practical network solutions.
- Enable secure, resilient connectivity to external partners, data sources, and service providers from cloud platforms.
Technical Leadership
- Own network architecture standards, design artefacts, and reference documentation.
- Serve as the final technical decision-maker for cloud networking approaches and vendor technologies.
- Coach and guide engineers, shaping best practices across platform and infrastructure teams.
Job Requirements:
- 812 years in network engineering or architecture, with significant recent exposure to cloud and hybrid environments.
- Strong hands-on experience designing and operating Microsoft Azure networking.
- Proven practical experience with:
+ Virtual network / VPC design and routing
+ Private cloud connectivity
+ Load balancing, firewalling, and NAT
- Proven understanding of hybrid and multi-cloud connectivity models.
- Strong fundamentals in networking concepts such as routing protocols, redundancy, and fault isolation.
- Experience delivering highly available, geographically distributed systems.
- Working knowledge of infrastructure automation, CI/CD integration, and configuration management.
- Able to explain complex architectural decisions clearly to both engineers and business stakeholders.
- Comfortable operating in environments with rapid change and high accountability.
- Practical and balanced in decision-making, weighing performance, security, cost, and operability.
Nice-to-Have
- Exposure to latency-sensitive or high-throughput workloads.
- Familiarity with container networking, private platform services, or service mesh architectures.
- Relevant certifications in cloud networking or advanced network design are a plus.
