The Role:

We are looking for an experienced Senior M365 Security Consultant to join our leading Microsoft Security Practice. In this role, you’ll help organisations design, improve, and mature their Cyber Security posture through the use of M365 Security and Compliance technologies. 

This is a client-facing, senior-level role where you’ll combine deep hands-on technical expertise with strong consulting skills. You’ll own engagements end-to-end: from discovery and strategy through to design and implementation.

  • Shape Strategy: Help clients define security strategies, roadmaps, and policies across organisations of varying sizes and maturity. 

  • Hands-On: Lead implementations, tenant migrations, and greenfield deployments translating designs into secure, usable solutions. 

  • Support Pre-Sales: Collaborate with sales teams on solution design, provide technical input, and contribute to Statements of Work and proposals. 

What You’ll Bring 

You’re an experienced M365 security professional who is comfortable working independently, engaging directly with customers, and making informed technical decisions. 

Strong experience with Microsoft 365 security and compliance technologies, including: 

  • Microsoft Purview 

  • Microsoft Defender for Endpoint

  • SC-300 – Microsoft Identity and Access Administrator 

  • SC-400 – Microsoft Information Protection and Compliance Administrator 

  • MS-500 – Microsoft 365 Security Administrator Associate 

  • MS-102 – Microsoft 365 Administrator 

What Sets You Apart 

  • You’re comfortable operating as a trusted advisor, not just a technical implementer 

  • You can influence stakeholders from engineers through to senior leadership 

  • You take a pragmatic, outcome-focused approach to security 

  • You enjoy variety and can manage multiple client engagements without losing quality 

  • You’re curious, motivated, and keep up with evolving threats and Microsoft capabilities
