About this role

As a Security Specialist, you'll be part of a wider team delivering critical security solutions for our banking customers. Working closely with customers daily, you'll translate business and technical requirements into high-quality designs and successful implementations, while remaining mindful of security strategy, governance, risk, and compliance objectives.

You'll combine strong technical expertise with excellent stakeholder engagement skills, helping customers navigate complex security challenges and delivering solutions that protect their most critical assets.

There's nothing quite like seeing a world-class security design come together—from initial concept through to implementation—before successfully handing over to our Delivery and Operational teams.

What you'll be doing

• Provide technical security leadership and oversight across a strategic banking customer contract, ensuring services and solutions remain aligned to contractual security obligations, governance requirements, and customer security strategy.

• Work closely with customers to understand their threat landscape, risk profile, regulatory obligations, and strategic objectives, ensuring security solutions address both current and emerging challenges.

The skills you will need

• Have excellent stakeholder management and communication skills, with the ability to engage confidently with customer technical teams, senior leadership, project managers, risk and compliance functions, and third-party suppliers.
• Have experience delivering large-scale, complex, and technically challenging security or infrastructure projects, taking ownership from requirements gathering through to design, implementation, and operational handover.
• Have experience designing and implementing security solutions across cloud and hybrid infrastructure environments, with an understanding of modern security architectures and cloud security principles.
• Possess strong technical expertise across a broad range of security and networking technologies, with hands-on experience and working knowledge of some of the following:
