Senior Network Engineer

Overview

This is a Senior Network Engineer role within a global energy organisation, based in Aberdeen, supporting a large-scale campus network environment with international reach. You’ll join a small, highly skilled team, giving you real ownership across design, delivery, and 3rd line support. This isn’t a siloed role — you’ll be involved in everything from architecture decisions through to hands-on troubleshooting.

There is also the opportunity to travel to global sites (South America, South East Asia, UAE, and the USA) for project work if that’s something you enjoy — but it’s optional, not mandatory.

If you’re looking for a role where your technical input genuinely shapes the network and you’re not just another escalation point in a huge team, this is it.

• Design and deliver campus network solutions across LAN, wireless, and SD-WAN environments.
• Act as the 3rd line escalation point for complex network and security issues.
• Support and optimise a Cisco-based LAN and wireless infrastructure.
• Implement and maintain Palo Alto firewall solutions.
• Deploy and support HPE Aruba SD-WAN across global sites.
• Contribute to network architecture, standards, and continuous improvement.
• Work closely with global stakeholders on project delivery.
• Produce and maintain clear technical documentation.

Skills / Must Have:

• Proven experience in a Senior Network Engineer role.
• Strong Cisco LAN and wireless background.
• Hands-on experience with Palo Alto firewalls.
• Experience with SD-WAN technologies (Aruba preferred).
• Ability to operate across design, delivery, and 3rd line support.
• Strong troubleshooting and problem-solving skills in enterprise environments.
• Comfortable working as part of a small, collaborative team.

Nice to Have:

• Experience in oil & gas, energy, or other global enterprise environments.
• Interest in occasional international travel for project work.

• Based in Aberdeen.
• On-call rota: 1 week in 5 (with additional allowance).
• High level of technical ownership and influence.
• Opportunity to work across global network environments.
• Optional international travel for project delivery.
• Close-knit team with strong collaboration and knowledge sharing.
• Up to £60,000 per annum + on-call allowance.
