You will act as a key contributor in shaping our clients technology direction, while ensuring all solutions align with security, performance, and compliance standards.

You will work across multiple projects and operational workstreams, partnering with internal teams and external service providers to design, document, and guide the implementation of high-quality, scalable, and secure technology solutions.

Key Responsibilities:

• Lead the end-to-end design of solutions across infrastructure and application domains, from high-level architecture to detailed technical specifications.

• Produce comprehensive High-Level Designs (HLDs) and Low-Level Designs (LLDs) that serve as authoritative blueprints for implementation by internal teams and third-party vendors.

• Act as the subject matter expert for network and infrastructure design, including Cisco-based networking, security layers, and integration between systems.

• Define and document integration patterns, security configurations, and operational processes across both on-premise and cloud-based platforms.

• Collaborate with stakeholders to gather technical requirements, ensuring solutions are fit-for-purpose and aligned with business goals.

• Work closely with external vendors and service providers to communicate design intent, resolve technical issues, and oversee successful delivery.

• Evaluate technology options and make recommendations that balance innovation, cost, security, and long-term maintainability.

Key Skills & Experience:

• Proven experience designing and delivering infrastructure and networking solutions in complex enterprise environments.

• Strong knowledge of Cisco technologies, including switches, firewalls, routing, and network segmentation.

• Expertise in producing HLDs/LLDs, technical documentation, and architecture artefacts to support development and delivery teams.

• Deep understanding of network integration, including firewall configuration, VPNs, load balancers, and secure connectivity with third-party systems.

• Experience working with and managing third-party vendors and MSPs, with the ability to provide clear technical direction and hold suppliers accountable to agreed designs.

• Broad infrastructure knowledge including servers, storage (SAN), Wi-Fi, CCTV, and UPS systems.

• Familiarity with Microsoft Azure, M365, and hybrid cloud environments.

• Ability to communicate complex technical concepts clearly to both technical and non-technical audiences.
