Information Security Officer

 
Information Security Officer
Location: London
Department: Risk and Compliance
Reporting to: Head of Risk and Compliance
ABOUT NEXGEN CLOUD:
NexGen Cloud is the company behind Hyperstack, a full-stack AI cloud serving tens of thousands of customers from AI researchers to enterprises running the world's most compute-intensive workloads. We deliver on-demand and private GPU infrastructure to teams who treat performance as a requirement, not a feature.
We're a tight-knit, fast-moving team working at the cutting edge of AI cloud infrastructure. We practice what we preach, equipping our people with AI at every level so we can solve harder problems, ship faster, and keep raising the bar for what enterprise GPU infrastructure looks like.
THE ROLE: Information Security Officer
This role exists because as we scale our infrastructure and customer base, protecting the systems, data, and trust that underpin Hyperstack is a business-critical priority. You'll have direct ownership over NexGen Cloud's information security posture — from policy and risk frameworks through to incident response and compliance programmes.
This is a role for someone who operates independently, thinks in systems, and understands that good security is both a technical and a business discipline.
WHAT YOU'LL BE DOING:
Rather than a long checklist, here's what success in this role looks like:
Own the development and maintenance of data security policies, standards, and procedures across the organisation
Drive the information security roadmap, coordinating activities across Risk and Compliance, Engineering, and Operations
Lead risk and vulnerability assessments, ensuring findings translate into prioritised remediation actions
Oversee data classification, encryption, and access control frameworks
Lead incident response planning, investigation, and remediation — including playbooks, communications, and documentation — tracking actions through to closure
Collaborate with Engineering, DevOps, Legal, and Compliance to embed security by design
Manage third-party security risk and vendor assessments, escalating material risks appropriately
Build and deliver security awareness programmes across the organisation
Maintain documentation for audits and regulatory reporting
ABOUT YOU:
We're more interested in how you think and work than in a perfect CV. You'll likely bring a combination of the following:
Essential
Strong knowledge of data protection laws and regulatory frameworks
Experience in cloud security environments
Deep understanding of encryption, IAM, network security, and secure architecture principles
Proven experience in incident response and risk management
Familiarity with security standards such as ISO 27001, SOC 2, NIST
Ability to translate technical risks into business impact for non-technical stakeholders
Strong communication and cross-functional collaboration skills
Certifications are a plus (e.g. Security+, ISO 27001 Foundation, CC); advanced certifications (CISSP, CISM, CCSP) welcomed but not required
Nice to Have
Experience in HPC, GPU, or AI/ML cloud environments
Background in SaaS, IaaS, or enterprise cloud infrastructure security
Experience with zero-trust architecture implementation
Knowledge of container and Kubernetes security
Familiarity with DevSecOps practices and CI/CD security integration
Exposure to international data transfer frameworks and multi-region compliance
Experience with SIEM, SOAR, and advanced threat detection platforms
Involvement in external security audits and penetration testing programmes
Experience leading security certifications or accreditation programmes
WHAT WE OFFER:
Competitive salary and annual discretionary bonus scheme
Employee wellbeing benefits
25 days of holiday, plus public holidays
Flexible working arrangements (remote or hybrid, depending on role and location)
Real ownership and autonomy, with the trust to take initiative and experiment
The opportunity to make a visible, meaningful impact as we scale
Clear career progression and growth opportunities in a fast-growing company
A collaborative, international culture built on trust, transparency, and ownership
The chance to help shape NexGen Cloud's team, culture, and future alongside ambitious, mission-driven colleagues
