We're partnering with a growing MSP to appoint a Senior Network Engineer to lead the design and delivery of complex, enterprise-grade network solutions across a diverse customer base.

This is a hands-on, client-facing role - ideal for someone who enjoys owning solutions end-to-end, from discovery and design through to delivery and optimisation. You'll work closely with technical teams, stakeholders, and pre-sales functions to design scalable, secure, and high-performing network environments.

Please note this role includes periodic after-hours and overnight work to support client migrations and change windows outside business hours, minimising disruption to client operations. Time off in lieu / flexible scheduling is provided.

- Collaborate with stakeholders to gather requirements and translate business needs into technical solutions
- Support pre-sales activities, including solution design, client presentations, and proposals
- Develop proof of concepts (PoCs) and contribute to cost estimation and project planning




- Ensure solutions are aligned to best practice across security, resilience, and scalability
- Plan and execute network changes and migrations during scheduled maintenance windows, including evenings/overnight as required
