Information Security Architect

Information Security Architect - Information Security

Office first

Team description

SumUp's Information Security team protects a payments platform used by millions of small businesses, which means the work here directly shapes whether merchants can trust us with their money every single day. As an Information Security Architect, you'll help decide how security gets built into new products from day one, from mobile payments to the secure use of AI, while also stepping in as a senior responder when things go wrong. It's a role that sits at the intersection of prevention and response: you'll shape the architecture that stops incidents from happening, and you'll be in the room leading the response when they do anyway.

What you'll do

• Define security architecture requirements for high-risk initiatives, including PCI PIN, payment processing, and mobile payment surfaces
• Build automation for security architecture assurance and incident response, such as policy-as-code, detection-as-code, and SOAR workflows
• Lead incident triage, investigation, containment, and remediation for complex, high-severity security incidents
• Develop and improve incident response playbooks and detection automation with the wider security team
• Coordinate with Engineering, Platform, IT, Product, Risk, and Compliance to validate security before launch
• Maintain a prioritised security roadmap that balances architecture work with lessons learned from incidents

You'll be great for this role if…

• More than 8 years of security experience, typically including at least three years focused on security architecture and substantial hands-on incident response
• Strong knowledge of SIEM/SOAR/CNAPP systems
• Experience working with modern Cloud vendors (AWS/AZURE/GCP) & SaaS solutions (Vercel, n8n, Cloudflare, Langdock, Cursor, IncidentIO, Notion, Vanta)
• Strong knowledge of payment security standards, including PCI DSS and PCI PIN
• Experience building or improving detection as code, security automation pipelines, or workflow automation tools
• Comfort translating architecture decisions and incident risk into clear language for senior stakeholders
• Track record of leading response during high-severity incidents while balancing multiple cross-functional priorities
