Information Security Officer

Your Role in Our Story: 

ACT is strengthening its data, technology and AI capabilities as we build a more integrated digital platform alongside our core environmental commodities trading and market-making business. This transformation is commercially driven, enabling us to scale, deepen client relationships and support increasingly complex and digital markets.

As Senior Information Security Officer, you will own ACT’s enterprise information security strategy and governance at Group level, spanning our core operations, emerging digital businesses and client-facing technology platforms. You will define the security risk appetite, lead our response to an evolving threat landscape, and ensure security and resilience are embedded by design as our technology landscape develops.

Working across business and technology leadership, you will translate commercial ambition into a pragmatic and scalable security posture that protects our systems and data while maintaining the trust of clients, counterparties and regulators. In essence, your role involves:

Strategy & Governance

• Own the Group-wide information security strategy and roadmap across ACT’s core market-making business and digital and client-facing platforms, aligned with business goals and industry frameworks such as ISO 27001 and NIST CSF. Define and maintain ACT’s cyber risk appetite.
• Establish and lead security governance, including policies, standards and control frameworks, with clear accountability across the Group. Report on security posture and material incidents to executive leadership and, where relevant, the Board.

Client Platforms & Secure-by-Design

• Embed security-by-design into new products and client platforms, partnering with Data, Architecture and Commercial teams to ensure emerging digital capabilities are secure from inception, while acting as a credible security voice to clients and counterparties.
• Oversee application, product and SaaS security, embedding security throughout the software development lifecycle for internal and client-facing platforms, and assessing third-party services handling ACT and counterparty data.

Risk & Resilience

• Lead enterprise security risk management, including risk assessments, vulnerability management and third-party/supply-chain risk, driving timely mitigation across core and digital environments.
• Direct incident preparedness and response, coordinating detection, containment, eradication and recovery, while continuously strengthening incident and crisis-management plans.
