Security Post Sales Architect and Infrastructure Consultant (AIR)

LevelBlue 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, LevelBlue elevates client outcomes that matter: stronger defense, faster response, and sustained business continuity. LevelBlue 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.

About the Role

LevelBlue’s Professional Services Organisation is seeking an experienced Cyber Security Consultant to join our growing Security Consulting practice. This is a client-facing delivery role focused on helping organisations across a range of sectors identify, assess, and address their most pressing security challenges — spanning SIEM, Identity, security architecture review and Endpoint Detection & Response (EDR) technologies. As a Cyber Security Consultant, you will work across the full engagement lifecycle — from scoping and discovery through to delivery, reporting, and client presentation. You will operate with a good degree of autonomy on engagements while drawing on the wider LevelBlue practice for specialist support and peer review. The role suits someone with a solid technical foundation who is equally comfortable translating findings into clear, business-relevant guidance for client stakeholders at all levels. This role offers a clear development pathway toward Senior Consultant and Principal Consultant levels within the LevelBlue Professional Services career framework, with access to structured mentoring, certification support, and exposure to a broad portfolio of client environments.

• Practice Contribution
• Contribute to the development and maintenance of LevelBlue service methodologies, delivery templates, proposal assets, and internal knowledge resources.
