Appvia is a specialist cloud, platform, and solutions engineering consultancy, helping organisations modernise infrastructure, improve reliability, and adopt cloud-native practices that enable long-term, sustainable delivery.
Our engineering capability spans AWS, Azure, platform engineering, networking, software, data, AI, delivery, and managed services.
We work across complex, high-impact environments in both the public and private sector, delivering solutions where security, resilience, scalability, and operational excellence are critical.
We're hiring a Senior Network Engineer to join Appvia on a new secure public sector engagement, taking a lead role in a significant Cisco SD-WAN migration and transition programme.
This is a senior, hands-on role with real ownership: you'll take the lead on complex network changes and migration activity, peer review network designs produced by others, gather and analyse network requirements, and directly support senior architects in preparing material for formal design and security governance boards. You'll also coach and mentor more junior network engineers as part of building out the wider team's capability.
This role sits above our Network Engineer role in seniority - where that role focuses on implementing and supporting designed network services, this role owns migration workstreams end-to-end, reviews the work of others, and takes on a mentoring and technical leadership responsibility within the team.
Interview Process - 3 Stage
You must hold active UK Security Clearance (SC). NPPV3 clearance is highly desirable.
You are an experienced Senior Network Engineer with strong Cisco networking fundamentals, comfortable taking ownership of complex network migration work, reviewing the designs of others, and mentoring more junior engineers.
You will bring:
