Senior Network Engineer

Senior Network Engineer

Glasgow, UK - Hybrid

£75,000 - 95,000 - Depending on experience & qualifications

We are proud to be supporting a fast-growing technology company at the forefront of satellite and cloud infrastructure in their search for a Senior Network Engineer. Because this engagement is sensitive, we'll share the client's name with candidates at the shortlisting stage.

THE OPPORTUNITY

Our client is building a next-generation network connecting satellites, ground stations, and cloud infrastructure. Operating across dynamic, intermittent links, their platform is designed to deliver data reliably into cloud-based workloads, a technically complex challenge requiring deep networking expertise.

This role sits at the heart of their edge infrastructure, the servers and network devices deployed on-site at antenna locations to receive, demodulate, and transport satellite data to the cloud. It is a hands-on, high-ownership position spanning routing, overlay networking, edge systems, and cloud connectivity.

KEY RESPONSIBILITIES

Network Design & Architecture

• Design L3 network topology across satellite, ground, and cloud environments
• Define IP addressing schemes, segmentation, and routing domains
• Model connectivity patterns and failure scenarios

Routing & Connectivity

• Implement and operate dynamic routing protocols
• Design route advertisement, filtering, and failover strategies
• Handle intermittent and flapping connectivity gracefully

Overlay & Secure Networking

• Build secure multi-hop paths with strong encryption and isolation
• Implement secure tunnel configurations (WireGuard / IPsec)
• Define and enforce SSH access policies, firewall rules, and least-privilege communication

Automation & Infrastructure

• Develop automation pipelines using Terraform and Ansible
• Support scalable rollout and configuration management across distributed sites

Operational Integration

• Align networking behaviour with satellite scheduling and operational windows
• Design safe state transitions and failover scenarios
• Improve observability, monitoring, and alerting across the stack

WHAT WE'RE LOOKING FOR

Our client is seeking a Senior Network Engineer with strong technical fundamentals and a genuine passion for solving complex infrastructure challenges. You'll be comfortable working across architecture, implementation, and troubleshooting, and you take strong ownership of everything you touch.

Essential Experience

• Advanced-level experience with IP networking and routing
• Hands-on BGP experience covering design, operation, and troubleshooting; familiarity with distance-vector protocols
• Solid Linux networking skills, including VLANs, MTU, TCP/IP, and complex NAT
• Proven experience designing and operating VPNs and tunnelling technologies in distributed environments (WireGuard, StrongSwan, GRE + IPsec)
• AWS networking expertise: VPC, TGW, Cloud WAN, VPN, and edge or hybrid networking
• Strong grasp of overlay vs underlay networking principles
• Extensive infrastructure automation experience with Terraform, Ansible, or equivalent
• Scripting or coding ability in Python
• Proven ability to debug complex, distributed systems

Desirable

• Exposure to satellite, telecom, or RF systems
• Experience with hardware operations, rack installation, or cable management
• Broader cloud platform experience beyond AWS

WHY THIS ROLE STANDS OUT

• Work on genuinely novel infrastructure at the intersection of space, ground, and cloud
• High ownership from day one, you'll design and ship, not just maintain
• Join a technically exceptional team building something with real-world impact
• Shape architecture at an early stage of a complex, mission-critical system
• An opportunity that sits at the cutting edge of clean technology infrastructure
