Security Engineer

About the role

ABOUT US

At Datatonic, we are Google Cloud's premier partner in AI, driving transformation for world-class businesses. 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

KEY RESPONSIBILITIES

- Improve and tune SIEM detection rules and alerting workflows

- Identify gaps in detection coverage and develop pragmatic detection improvements based on evolving risks and changes in our environment

- Enhance DLP and secure web gateway controls

- Monitor and remediate findings from CASB and ISPM platforms

- Investigate security alerts and incidents, including root cause analysis

- 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
