Original job description

Job Description

On behalf of our client, Affinity is seeking a hands-on Senior Network Engineer to support a large-scale Cisco infrastructure refresh across a complex enterprise environment. This is a delivery-focused role where the successful candidate will execute approved network designs through build, testing, implementation, and post-cutover validation. Working within a highly regulated environment, the engineer will be responsible for end-to-end network changes, including configuration, change management, troubleshooting, documentation, and maintenance window execution.

Responsibilities

Execute switch and router replacements across data centre, branch, and campus environments - staging, configuration, cutover, and validation
Build and standardize configurations from approved templates; identify and flag drift
Own your changes end to end: write the change record, present it at CAB, execute in the window, validate, and close
Troubleshoot L2/L3 issues under time pressure during and after cutovers, including rollback decisions
Perform pre-cutover discovery and dependency mapping on legacy gear
Update as-builts, diagrams, and IPAM records - accurately, without being chased
Coordinate directly with app teams, security, facilities, and vendors to sequence work
Work independently across multiple concurrent sites with minimal supervision

Qualifications

8+ years hands-on enterprise network engineering, with the majority in operations and implementation rather than design
Deep Cisco routing and switching: Catalyst (9000 series), Nexus (NX-OS, vPC, VDC), ISR/ASR, IOS-XE
Demonstrated delivery on at least one large-scale hardware refresh or migration program
Strong core protocol depth: BGP, OSPF, EIGRP, spanning tree, VLANs, VRFs, HSRP/VRRP, QoS
Proven experience in banking, insurance, or capital markets - you understand regulated change control, segregated environments, and why a failed window is a serious event
Comfortable working in ITIL change management (ServiceNow or equivalent) and writing your own change records
Willing and available to work scheduled evening and weekend maintenance windows
Self-directed: takes a work package, asks the right questions once, and delivers without daily direction
CCNP or CCIE (R&S / Enterprise Infrastructure)
Cisco ACI, SD-WAN (Viptela), DNA Center / Catalyst Center
Cisco ISE and 802.1X in a production financial environment
Firewall exposure (Palo Alto, Cisco ASA/FTD)
Automation for repetitive config work - Python, Ansible, or Netmiko
