What you will do:

Help shape how Sidetrade protects its business, its customers and the AI-powered software they rely on. As Senior Manager, Cyber Security, reporting to our CISO, you will develop and execute our operational security strategy, lead security improvements across the business and build the capabilities needed to respond confidently to evolving threats.

Working closely with Engineering, Platform and IT, you will influence architecture and development decisions, strengthen detection and response, and translate security risks into clear business priorities. You will join our international R&D team, which brings together engineering, data and AI expertise to build software for business-critical financial processes, where security is central to the trust our customers place in us.

You will lead the operational security roadmap and work with the owners of our products, infrastructure and corporate systems to deliver it. Alongside the colleagues responsible for governance and compliance, you will turn security requirements into practical controls and evidence of their effectiveness. In this role you will:

• Security strategy and risk: prioritise the risks that matter most, agree a practical improvement roadmap and communicate progress and investment needs to senior leaders.
• Security operations and response: develop the team and SOC capability, strengthen detection and investigation, and coordinate incident response and lessons learned.
• Product and platform security: embed security into architecture and the development lifecycle, partnering with engineering teams on threat assessment, testing and remediation.
• Assurance and improvement: oversee vulnerability assessments and penetration testing, manage security suppliers, and use meaningful measures to improve control effectiveness.
• Security as our AI capabilities evolve: work with our engineering and AI teams to assess emerging risks and establish practical safeguards for AI-enabled products, including protecting sensitive data, controlling access and permissions, and ensuring appropriate monitoring and oversight.

What you will bring:

• Significant experience in operational cyber security, including leading people or major security programmes and delivering measurable improvements.
• Practical experience of incident response, vulnerability management and security monitoring, with the judgement to prioritise under pressure.
• Strong understanding of cloud and infrastructure security, identity and access controls, and secure software development.
• The ability to work constructively with engineers and business leaders, explain risk clearly and make proportionate decisions.
• Experience turning security strategy into a deliverable roadmap, coordinating stakeholders and managing security suppliers.
• Curiosity and sound security judgement about AI-enabled products. Deep AI specialism is a useful addition rather than a prerequisite.
• Fluent English and confidence working with international teams. French is welcome but not required.
