Senior Information Security Engineer

Help us protect the future of banking

At Zempler Bank, we're building a modern banking platform designed to support the UK's small businesses and entrepreneurs. As we continue to grow, security remains at the heart of everything we do.

We're looking for a Senior Information Security Engineer to join our Technology & Security Operations team. This is a hands-on role where you'll help design, build and continually improve the security controls, tooling and processes that protect our cloud, application, Microsoft 365 and infrastructure environments.

You'll work across security engineering, threat detection, incident response, vulnerability management, cloud security and cyber resilience, partnering closely with engineering teams and our external Security Operations Centre to strengthen our security posture and stay ahead of emerging threats.

What you'll be doing

• Building and improving security controls across our cloud and Microsoft 365 environments
• Developing detections, automations and response capabilities using SIEM, SOAR and security tooling
• Investigating and responding to security incidents and helping drive lessons learned
• Conducting threat hunting and using threat intelligence to identify potential risks
• Managing vulnerabilities and partnering with teams to prioritise remediation
• Supporting secure development practices and embedding security into delivery pipelines
• Contributing to security architecture, threat modelling and technical design reviews
• Helping improve cyber resilience, recovery capabilities and operational security processes

What we're looking for

We're interested in people who bring a blend of security operations, engineering and cloud security experience. You don't need to tick every box, but we'd love to hear from you if you have experience with:

• Security Engineering, Security Operations or Cloud Security
• Microsoft Azure (preferred), AWS or GCP
• SIEM and SOAR platforms such as Microsoft Sentinel or Splunk
• Microsoft Defender, Entra ID, EDR/XDR and identity security technologies
• Incident response, threat hunting and vulnerability management
• Scripting and automation using tools such as PowerShell, Python or Terraform
• Working collaboratively with engineers to build secure, scalable solutions

Why join Zempler?

This is an opportunity to join a growing bank where security has a genuine voice at the table. You'll work with modern technologies, tackle meaningful security challenges and play a key role in protecting both our customers and our colleagues.

Most importantly, you'll be joining a collaborative team that values curiosity, continuous improvement and doing the right thing.

We operate a hybrid working model, with this role based from our London Bridge office and colleagues coming together once a week.
