Job Description
The Network Security Architect will lead the development of security strategies and roadmaps, translate business requirements into secure network designs, and oversee the deployment of security technologies such as firewalls, Intrusion Detection/Prevention Systems (IDPS), VPNs, and SIEM solutions. You will conduct security assessments, vulnerability analyses, and penetration testing, providing recommendations for remediation and improvement. A key aspect of this role involves staying abreast of the latest security threats, vulnerabilities, and technologies, and proactively integrating this knowledge into our security posture.
Collaboration is key; you will work closely with network operations, engineering teams, and other IT stakeholders to ensure security is embedded into all network development and operational processes. You will also be involved in incident response planning and execution, ensuring swift and effective mitigation of security breaches. The ability to articulate complex technical security concepts to both technical and non-technical audiences is essential.
Ideal candidates will possess a Bachelor's degree in Computer Science, Information Security, or a related field, with a minimum of 5 years of experience in network security architecture and design. A strong understanding of network protocols (TCP/IP, BGP, OSPF), security standards (ISO 27001, NIST), and relevant certifications such as CISSP, CCIE Security, or similar are highly desirable. Proven experience with cloud security principles (AWS, Azure) and specific security tools is also a significant advantage. This role requires a dedicated professional who is passionate about cybersecurity and committed to protecting critical infrastructure. The position is based in our Milton Keynes office, offering a dynamic and challenging work environment.
