We're currently looking for an experienced Senior Microsoft 365 & Email Platform Architect to join our IT team on a full‑time, permanent basis to help deliver our Modern Workplace strategy.

First‑class IT systems are absolutely key to the success of any business in today's commercial world and the legal sector is no exception. Womble Bond Dickinson (UK) LLP prides itself on being at the forefront of technological advancements within the legal profession, something we've become well known for. To remain competitive in our markets, and to continue supporting our growth strategies, our team of dedicated IT professionals have a key role to play, ensuring the integrity of the IT infrastructure, development of new and existing systems and excellent support to all of our employees, and clients.

This role provides strategic ownership and architectural leadership for the firm's Microsoft 365 and email communications platform.

The role designs and delivers sustainable, multi‑year solutions to ensure the platform remains secure, resilient, scalable and aligned with business strategy.

Key Responsibilities

• Acting as the architectural authority for email‑driven integrations, you will define target architectures spanning email, identity and security across Microsoft and third‑party platforms, and lead the delivery of well‑designed, supportable platform improvements.
• Security and compliance are embedded by design. You will ensure email and identity controls meet regulatory, audit and client assurance requirements, oversee email‑related incident response, and drive continuous improvement following incidents.
• You will also provide architectural assurance, produce clear standards and documentation, and act as a senior technical advisor to stakeholders across IT and the wider business.

What we are looking for?

• Architectural ownership of Microsoft 365 and Exchange Online in complex, regulated or professional services environments.
• Experience designing and delivering long‑term M365 and email platform roadmaps.
• Strong end‑to‑end solution design across email, identity, security, collaboration and third‑party integrations.
• Hands‑on integration with enterprise email security platforms (e.g. Mimecast), including policy design and mail routing.
• Proven accountability for platform outcomes, architecture quality and technical direction.

• Strong understanding of secure M365 configuration baselines and client‑assured environments.
• Purview (data governance/compliance) knowledge beneficial.
• Firewall knowledge (ports/applications/rulesets) also beneficial.

Minimum requirements

• Deep, hands‑on experience with Exchange Online and Microsoft 365 in complex enterprise environments.
• Strong architectural understanding of identity‑driven communication platforms.
• Proven experience designing and delivering long‑term platform solutions, not just BAU support.
• Strong understanding of how email security platforms (e.g. Mimecast) integrate with Microsoft 365.
• Ability to balance risk, usability, compliance and future scalability.
• Experience operating in regulated or highly client assured environments.
• Comprehensive expertise in mail security, including DMARC and Defender configuration.
• Proven proficiency in setup of data classification and Data Loss Prevention (DLP) controls.
