Security Consultants (Multiple Hires) London / Bristol / Manchester

Security Consultant – Enterprise / Cloud / Transformation

Location: UK (Hybrid – client site as required)

Salary: Competitive + bonus + benefits

Entasis Partners is working with a global consultancy delivering complex transformation programmes across public and private sector organisations.

They’re looking for a Security Architect to take ownership of security design across large-scale programmes – shaping architecture, influencing engineering teams, and ensuring security is embedded into delivery from day one.

This isn’t a purely advisory role. You’ll be expected to drive outcomes, work closely with delivery teams, and make decisions that stand up in complex, fast-moving environments.

The Role of the Security Architect

You’ll be responsible for defining and delivering security architecture across a range of programmes, typically involving cloud, integration, and platform modernisation.

This will include:

• Owning end-to-end security architecture across projects and programmes
• Producing architecture across high-level design through to implementation
• Embedding security into delivery teams, working closely with engineering and product functions
• Identifying risk early and putting in place practical, scalable controls
• Reviewing existing environments and driving improvements without slowing delivery
• Acting as the security point of authority across stakeholders, including senior technical and non-technical audiences

You’ll be working across multiple engagements, so the ability to adapt quickly and operate with autonomy is key.

What They’re Looking For from the Security Architect

• Strong background in security architecture within complex environments
• Experience delivering across large-scale transformation, infrastructure, or integration programmes
• Ability to move between strategy and hands-on delivery
• Confident engaging with stakeholders across engineering, architecture, and leadership
• Comfortable working in fast-paced, delivery-led environments

Certifications (desirable, not essential):

CISSP, CISM, TOGAF, SABSA or equivalent

Environment

• Hybrid model - typically 2–3 days on client site (can vary by programme)
• Exposure to a range of sectors and technology stacks
• Delivery-focused culture - less hierarchy, more ownership
• Opportunity to stay on a technical career path without moving into people leadership

Additional Info

Some roles may require UK security clearance, so candidates should be eligible (typically 5 years UK residency).
