Description

We are seeking an IT Operations & Security Manager to own and operate Aptem’s Corporate IT environment. You will oversee the health, security, and lifecycle of our identity platforms, physical assets, and core operational services.

Working closely with the Head of Infrastructure, you will help shape the direction and delivery of Corporate IT and Security roadmap. This is a technical, hands-on leadership role where you will solve problems, improve systems, and make decisions that move us forward.

The role is central to ensuring that our internal technology estate remains secure, reliable, scalable, and aligned with business and compliance requirements.

This is a remote role with one day per month on average spent at our London office requiring you to live within a reasonable commute to central London.

Key Responsibilities

You will be responsible for the day-to-day operation of Aptem’s Corporate IT systems. That means knowing what’s working, what’s not, where the risks are and delivering solutions to problems.

You will remain hands-on, acting as the escalation point for complex issues while contributing directly to configuration, troubleshooting, and continuous improvement across our Microsoft 365 and SaaS estate.

Corporate IT Operations & Service Delivery

Own the performance and reliability of Corporate IT services, ensuring a high-quality experience for all users. You will manage support workloads and priorities, ensuring incidents and requests are handled efficiently, while maintaining strong visibility of service health and risks. You will also oversee project delivery within the IT function, balancing operational demand with improvement initiatives.

Security & Compliance

Take ownership of the Corporate IT security posture, ensuring controls remain effective and aligned with ISO 27001 and Cyber Essentials requirements.

Work closely with Compliance and Platform teams to:

Manage identity and access controls (MFA, Conditional Access, least privilege)
Maintain endpoint security and device compliance
Respond to alerts, manage risks, and support audits

Identity, Devices & Asset Lifecycle

Own the lifecycle of identity, access, and physical IT assets across the organisation. This includes joiner, mover, and leaver processes, device provisioning and configuration, and refresh cycles for hardware. You will ensure asset inventory is accurate, access reviews are completed on schedule, and all devices meet defined security and compliance baselines.

Microsoft 365 & SaaS

Manage and optimise Aptem’s core IT platforms, including Microsoft 365, Entra ID, Exchange, Intune and other supporting SaaS platforms. You will ensure these platforms are well-configured, secure, recoverable and continuously improved, while also maintaining governance over the wider SaaS estate, including access control and integration with identity systems.

Continuous Improvement & Automation

Drive ongoing improvement across the IT function by identifying opportunities to automate processes, reduce manual effort, and enhance security and user experience. This includes implementing new policies, improving operational processes, and adopting Modern Workplace best practices.

Documentation & Governance

Own the documentation of IT systems, processes, and policies, ensuring they are clear, up to date, and maintained to an audit-ready standard. This supports internal governance, compliance requirements, and external due diligence activities.

Leadership & Collaboration

Lead the IT function day-to-day, providing clear objectives, performance feedback, and technical guidance to the IT Systems Administrator. You will work closely with senior business stakeholders to evolve Aptem’s IT strategy and ensure alignment with broader business goals.
