Principal Security Consultant; AIR

Level Blue reduces risk and builds lasting resilience so organizations can innovate and advance their mission with confidence. As the world’s most analyst-recognized and largest pure-play managed security services provider, Level Blue elevates client outcomes that matter: stronger defense, faster response, and sustained business continuity. Level Blue combines AI-powered security operations, advanced threat intelligence, and elite human expertise to provide the most comprehensive portfolio of strategic advisory, managed security, offensive security, and incident response services.

Level Blue’s Professional Services Organisation is seeking an experienced Principal Consultant to join our Architecture, Implementation & Remediation (AIR) consulting team. This is a senior, customer facing role focused on helping enterprise clients design, build, and optimise security operations capabilities - spanning SIEM, Identity, and Endpoint Detection & Response (EDR) technologies.

• Identify and document programme risks, assumptions, dependencies, and constraints; shape governance frameworks appropriate to engagement scale and client maturity.
• Build client technology roadmaps aligned to their security strategy, threat profile, and budget constraints.
• Manage scope and delivery expectations proactively, escalating commercial or delivery risks before they affect client outcomes.

• Partner with the sales team on select pre-sales opportunities - shaping technically credible solutions, building proposals, and presenting to prospective clients.
• Contribute to bid responses, scope definitions, and commercial frameworks for new and renewal engagements.

• Mentor and coach junior and mid-level consultants - providing technical guidance, delivery feedback, and career support.
• Contribute to the development of Level Blue service offerings, delivery methodologies, proposal templates, and internal knowledge assets.
• Maintain a current and evolving understanding of the threat landscape, emerging attack techniques, and relevant vendor platforms to inform client advisory and internal capability development.
• Represent Level Blue's AIR practice at industry events, client…
