• Coordinate with client stakeholders, architects, engineers, vendors and other delivery teams to resolve technical and operational challenges.
• Review network drawings, configuration standards, implementation procedures, test evidence and operational documentation for completeness and quality.
• Contribute to proposals, statements of work, solution demonstrations, effort estimates and other business-development activities.
• Coach team members, allocate work, review deliverables and promote consistent use of delivery methodologies, reusable assets and automation.

• Ability to manage multiple workstreams and deliver high-quality outcomes within agreed scope, schedule and budget.
• Sound understanding of infrastructure security services, governance models, operating models, controls and delivery methodologies.

• Strong analytical, problem-solving, facilitation, presentation and decision-making skills.
• Ability to communicate technical risks, architecture decisions and delivery concerns clearly to technical and business stakeholders.
• Experience supervising technical teams, reviewing deliverables, providing constructive feedback and supporting capability development.
• Commercial awareness and the ability to support scoping, effort estimation, resource planning and engagement financial management.
• A proactive, adaptable and collaborative approach in a fast-paced consulting environment.
• Ability to create and deliver domain-specific training and knowledge-sharing sessions.
• Understanding of automation opportunities that improve security operations, service quality and delivery efficiency.
• Willingness to travel and work flexibly when required by client or engagement needs.

To qualify for the role, you must have

• Customer-focused mindset with experience contributing to proposals, estimations and solution presentations.
• Relevant professional certification such as CISSP, CISM, CISA, SABSA, TOGAF, PRINCE2 or a leading vendor security certification.

What we look for
