SALARY: £47,790 - £53,100

LOCATION(S): Manchester or Leeds

WORKING PATTERN: Our work style is hybrid, which involves spending at least two days per week, or 40% of our time, at our locations noted above.

About this Opportunity

Are you looking to develop your career in cyber security and make a real impact in one of the UK’s biggest financial institutions? We’re looking for a Network Security Infrastructure Specialist to join our Network Security Prevention, Detection, Compliance and Assurance team – part of the Network Security & Traffic Management Lab at Lloyds Banking Group.

Our team plays a crucial role in protecting the bank by operating both threat prevention and detection technologies (like IDS, IPS and NDR) and ensuring compliance with network security policy through tooling and automation. As part of the Compliance and Assurance function, you’ll work with experienced engineers to manage and support the tools we use to monitor, enforce, and report on security policy across our on-prem and multi-cloud environment. It’s a great opportunity to develop your skills in network security, automation, and policy compliance – with support and guidance every step of the way.

What you'll be doing

• Support compliance tooling: Help configure, maintain, and operate the systems we use to enforce and evidence network security policy. You’ll work hands-on with leading security and automation tools that support policy compliance and firewall change management.

• Monitor and respond: Assist in monitoring policy compliance across our estate, contributing to reporting and resolving non-compliance issues that arise.

• Collaborate and learn: Work closely with senior specialists and partners across our network and cyber security teams. You’ll gain experience in how policy is implemented and enforced across large, complex environments.

• Drive continuous improvement: Contribute ideas to improve our processes and tooling – especially around automating manual tasks and ensuring accurate, auditable compliance.

• Grow your expertise: Develop your understanding of firewalls, network zones, policy automation and regulatory controls. We’ll support you in building a solid foundation in network security and compliance.

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

We're looking for someone with a keen interest in network security and a desire to grow their skills. You don’t need to be an expert – if you have a solid grounding and a willingness to learn, we’ll help you develop.

You should have:

• A basic understanding of network architecture, security zones, and how data flows between them

• Awareness of traditional and distributed firewalls, their purpose, and how rulesets control traffic

• An interest in automation – for both technical and business processes – and how it can improve compliance

• Familiarity (or a willingness to learn) tools used to enforce and monitor security policy such as Skybox, AlgoSec, FireMon, Tufin, or compliance-as-code frameworks

• A proactive approach – someone who enjoys solving problems, learning from others, and working as part of a team

• Good communication skills – you’re comfortable working with colleagues across different teams, asking questions, and sharing what you’ve learned

If you’re early in your cyber career or transitioning from a network-focused background into security, we encourage you to apply.
