Principal Cloud Security Engineer - London

ISS Stoxx is seeking a Principal Cloud Security Engineer to bring expert-level technical leadership to the development and deployment of our cutting-edge financial intelligence platform. We are in the early stages of a full-scale re-architecting of our on-prem estate to a modern componentized set of solutions using GCP technologies. In this IC role, you will collaborate with Principal Engineers to evolve and secure our platform architecture and interpret requirements and enterprise policies into requirements that maximize value in a secure way. You'll be an advocate of our platform architecture and solutions, demonstrating technical principles and business value.

You'll be able to demonstrate comfort and success in a matrixed organization where reporting lines do not dictate technical direction - in a culture where the global Platform Engineering function collaborate to achieve shared success. You will have a can-do approach, understanding that security engineering is a service function that must enable other teams to deliver value safely and have proven approaches to balance reactive and proactive work.

You'll be a humble expert, willing and able to meet people at their level and both help them and learn from them. You'll lead by example, using data and proof-of-concepts to bring people along and make them successful. You'll own deliverables as well as co-developing solutions with your peers and colleagues, to help other develop.


  • Drive the architecture, development, implementation and ongoing operation of Stoxx's GCP security posture
  • Ensure the platform's security meets regulatory, business and client requirements
  • Develop, build and support a robust security solution to support a modern cloud operating model
  • Lead cross-functional teams to implement the security roadmap
  • Drive continuous improvement initiatives to enhance pipeline performance and customer satisfaction
  • Keep abreast of emerging trends and technologies in cloud security and operations, and promote them across engineering and business functions
  • Act as a mentor for other team members, advising on best practice, technology and processes
  • Conduct audits and system reviews to ensure compliance with latest regulatory and security standards
  • Manage activities such as SAST, DAST and penetration testing
  • Work with counterparts in the wider ISS-Stoxx organization to ensure alignment of security standards


  • At least 7 years' experience in security operations or engineering, with a focus on cloud security and implementations, ideally in regulated financial services
  • A recognized industry certification such as CISSP, CISM, CISA
  • In-depth knowledge of security protocols and mechanisms
  • Hands-on technical background in cloud systems, networking and security
  • Good experience of at least one cloud provider (ideally GCP)
  • Ability to create scripts/tools as they relate to security
  • Experience in a microservices architecture/serverless security environment
  • Ability to troubleshoot, trace and diagnose API endpoint and network security issues
  • Strong documentation, communication and collaboration skills
  • Focus on simplicity, automation and observability
  • Experience coaching and mentoring high-performing teams
  • Pragmatic experience using agile to deliver incremental value
  • Experience working in a global or multinational team setting
  • Bachelor's or Master's degree in Computer Science or related field
