  • Design and implement network and security solutions
  • Analyse and resolve network performance issues
  • Provide expert-level fault resolution on advanced HFT network connectivity
  • Work closely with development, data centre, and project teams
Experience required for Network Engineer:
  • 4-8+ years' commercial network engineering experience
  • CCNA/CCNP certified
  • Financial services background required
  • Solid knowledge of OSPF, BGP, EIGRP, and IPSEC
  • Experience with network support
  • Scripting experience is a plus
  • Experience securing network infrastructure, including firewalls, network segmentation, and access control
  • Intrusion detection/prevention systems (IDS/IPS) and network monitoring for security threats
  • Understanding of security best practice within a regulated financial environment

Package:
Superb bonus, private medical insurance, contributory pension, free gym membership, 28 days holiday.
