Greater London, United Kingdom Women in Tech Full time

CGI is looking for an experienced Network Engineer to help shape secure, scalable, and future‑ready network architectures that enable mission‑critical outcomes across our Space, Defence and Intelligence business. In this role, you will design and optimise advanced on‑premises and cloud network solutions, working closely with engineering, cloud, and security teams to deliver high‑value innovations that drive real operational impact. We offer a competitive salary, excellent pension, private healthcare, and a share scheme that makes you a CGI Partner, not just an employee. CGI was recognised in the Sunday Times Best Places to Work List 2025 and named a UK ‘Best Employer’ by the Financial Times. We are committed to inclusivity, building a genuinely diverse community of tech talent and inspiring everyone to pursue careers in our sector, including our Armed Forces. Due to the secure nature of this programme, you will need to hold High Level Clearance or be willing to go through clearance. This position will require on‑site work. Key Responsibilities Design & Architect: Lead enterprise, virtual and cloud network designs across Cisco, Juniper, Arista and SDN/SD‑WAN ecosystems. Engineer & Optimise: Deliver routing, switching, and service provider technologies including BGP, OSPF, EVPN/VXLAN and MPLS. Secure & Protect: Implement advanced firewall, segmentation, PKI and zero‑trust controls across hybrid environments. Automate & Streamline: Apply automation, scripting and intent‑based networking to enhance reliability and operational efficiency. Integrate & Enable: Build cloud‑ready connectivity patterns across AWS, Azure and Google Cloud, including VPC/VNet design and interconnects. Monitor & Improve: Use observability and WAN optimisation tools to ensure high performance across global infrastructures. Required Qualifications To succeed in this position you should bring strong experience designing and operating complex network infrastructures across enterprise, virtualised and cloud platforms. You should be comfortable working with modern routing, switching, SDN/SD‑WAN, firewalls, PKI and cloud connectivity, and be able to collaborate across multiple technical disciplines. Extensive hands‑on experience with Cisco, Juniper, and/or Arista networking platforms. Strong knowledge of BGP, OSPF, IS‑IS, EVPN/VXLAN, MPLS and high‑availability protocols. Experience with SD‑WAN technologies (Cisco SD‑WAN, Meraki, Aruba, Palo Alto Prisma). Familiarity with AWS, Azure and/or GCP networking (VPC/VNet architecture, interconnects). Experience with NSX‑T/V, Nutanix AHV or Hyper‑V networking. Strong understanding of firewalls, load balancers, PKI and segmentation. Ability to work within secure environments and meet UK clearance requirements. Life at CGI is rooted in ownership, teamwork, respect and belonging. Here, you will reach your full potential because we call ourselves CGI Partners rather than employees, and we benefit from our collective success. Your work creates value: you’ll develop innovative solutions, build relationships with teammates and clients, access global capabilities, and have opportunities to deepen your skills and broaden your horizons. #J-18808-Ljbffr
