About this Opportunity
Join us at Lloyds Banking Group as a Network Security Senior Infrastructure Specialist and play a pivotal role in protecting the UK's largest digital bank. This opportunity sits within our Network Security Prevention, Detection, Compliance and Assurance team - part of the wider Network Security & Traffic Management Lab - which manages critical controls like Intrusion Prevention/Detection Systems (IPS/IDS) and Network Detection & Response (NDR) across our on-prem and multi-cloud environment. In this role, you'll lead the technologies that enforce our network security policies and keep our systems compliant in a dynamic, evolving threat landscape. It's a chance to drive automation in network security, influence future security architecture, and ensure we meet internal controls and external regulatory requirements - all while working in an inclusive, collaborative team that values your growth and ideas.
As a Network Security Senior Infrastructure Specialist, you will:
* Lead network policy compliance and automation: Design, build, and maintain tools that enforce network security policies and automate firewall rule changes, ensuring our firewall rulesets remain clean, efficient, and compliant with best practices.
* Monitor and assure security compliance: Implement mechanisms to continuously track network security compliance across our cloud and on-prem environments, providing evidence and reports to satisfy internal audit and external regulators.
* Drive security improvements: Proactively identify gaps or risks in network security posture and work with architects to shape new policies or architectural enhancements. Your insights will help influence future network security strategy and frameworks.
* Collaborate and innovate: Work closely with multi-functional teams in Cyber Security and IT to integrate compliance tooling and processes, improving our overall security monitoring and response capabilities. You'll also evaluate emerging solutions (such as compliance-as-code) to keep us at the forefront of automation.
* Mentor and guide others: Act as a technical leader within the team, sharing your expertise. You'll mentor junior engineers and influence a culture of continuous improvement, ensuring the whole team grows its network security skills.
Why Lloyds Banking Group
We're on an exciting journey to transform our Group and the way we're shaping finance for good. We're focusing on the future, investing in our technologies, workplaces, and colleagues to make our Group a great place for everyone. Including you.
What you'll need
* Extensive network/security experience: Deep technical knowledge of security boundary devices such as firewalls and intrusion detection/prevention systems
* Automation & tooling skills: Hands-on experience with automation workflows and policy administration tools (for example, AlgoSec, Skybox, Tufin, FireMon or similar), or exposure to "compliance-as-code" frameworks. You're comfortable using technology to simplify complex processes.
* Firewall policy expertise: Good understanding of firewall rule sets and network security policy standard practices - you know how to design and review rules that are effective, compliant, and minimize risk.
* Compliance and controls knowledge: Familiarity with regulatory standards and certification frameworks (e.g. ISO 27001, PCI-DSS) and experience participating in audits or maintaining key security controls. You understand how to translate regulatory requirements into practical network security measures.
* Leadership and collaboration: Demonstrable ability to lead initiatives and mentor junior technical staff. You enjoy sharing knowledge, guiding colleagues, and building an inclusive team environment. You communicate effectively and can influence partners when refining security policies or processes.
