We push the boundaries of technology with expertise in machine learning, data engineering, and analytics on Google Cloud. By partnering with us, clients future-proof their operations, unlock actionable insights, and stay ahead of the curve in a rapidly evolving world.
About the Role
We are looking for a hands-on Security Engineer to strengthen our security operations and take ownership of key risks and controls. This is the first dedicated security hire in the team and will play a central role in improving monitoring, detection, data protection, and automation across the organisation. This is an internal role focused on securing our own IT systems and infrastructure.
You will combine technical security engineering with practical compliance ownership, ensuring that our ISO 27001 and UK Cyber Essentials controls are not just documented, but effective and measurable.
As our first dedicated security engineer, you will help shape how security operates day to day. The scope is broad by design, but success in this role is not about doing everything at once. It is about understanding risk, making sound technical judgments, and prioritising the work that meaningfully reduces risk for the business.
We value pragmatism over perfection. You will be expected to identify gaps, propose improvements, and execute in a structured, risk-based way, focusing on impact rather than activity.
This role is ideal for someone who enjoys building, automating, and improving systems while taking real ownership and influencing how security evolves as the company grows.
Our Environment
We operate a cloud-first infrastructure of approximately 300 employees with Apple endpoints and minimal reliance on Microsoft technologies. Security controls are primarily implemented across SaaS platforms and cloud services, with a strong focus on automation and API-driven workflows.
Core stack: Okta, Google Cloud, Datadog, Island Enterprise Platform, Jamf, Vanta

Support vulnerability management across cloud, endpoints, and SaaS platforms, including prioritisation and remediation tracking
Maintain and improve incident response procedures, including playbooks, tabletop exercises, and post-incident reviews
Provide security input into internal enterprise technology decisions, including new SaaS integrations and cloud architecture changes
Automate repetitive security workflows and reporting
Reduce false positives and continuously improve signal quality
Automation and AI Enablement
Use scripting and automation to streamline security operations
Leverage AI tools responsibly to improve investigation workflows, reporting, and documentation
Identify opportunities where AI can improve efficiency without increasing risk
Build lightweight automation to reduce manual compliance overhead
Compliance and Control Engineering
Own and maintain selected compliance controls (ISO 27001)
Ensure controls are technically implemented and operating effectively
Maintain evidence and support internal and external audits
Track and remediate control gaps
Governance and Risk Support

What We’re Looking For
5–7 years of hands-on experience in information security
Practical experience operating and tuning security tools such as ISPM, SIEM, DLP, CASB, EDR, and related platforms
Solid understanding and real-world implementation experience of Zero Trust principles, including identity-based access controls, least privilege, device posture enforcement, and continuous verification
Experience in incident response and security investigations
Strong understanding of cloud logging, telemetry pipelines, and log source integration
Strong technical mindset with automation experience (Python, Bash, or similar scripting languages) to streamline security operations and reduce manual effort
Experience supporting ISO 27001 or similar compliance frameworks, including control ownership and audit readiness
Comfortable taking ownership of security controls, identifying gaps, and driving measurable improvements independently
Full professional fluency in English, with the ability to communicate clearly with technical and non-technical stakeholders
Nice to Have
Experience in cloud environments, especially Google Cloud
Experience with Infrastructure as Code such as Terraform or Pulumi
