About the Role

We’re looking for a high-performing Business Development Manager to drive growth across Federal, Defense, Critical National Infrastructure, and other high-security markets in the United States. This is a front-footed hunting role for someone who knows how to break into complex accounts, build influence, and convert opportunity into revenue. Focused on the Southeast U.S. territory, including Florida, Georgia, North Carolina, South Carolina, Alabama and Tennessee - you'll identify, pursue, and win new business opportunities while strengthening Gallagher Security's position in key markets.

You’ll lead go-to-market activity, create end-user demand, and work across partners, integrators, consultants, and internal teams to grow pipeline and win strategic business. Success in this role means consistently creating traction in the market and turning that momentum into long-term profitable growth.

What you’ll be doing:

• Win new business across federal, defense, intelligence, critical infrastructure, and other high-security markets in the U.S.
• Build and convert a strong pipeline of new logo and expansion opportunities that delivers against revenue and margin targets.
• Create end-user pull-through by engaging decision-makers, influencers, prime contractors, consultants, architects, and engineering partners.
• Position Gallagher as a trusted advisor through strategic customer conversations, solution shaping, and executive-level engagement.
• Partner closely with channel, technical, and field teams to develop winning strategies and move opportunities forward.
• Maintain strong forecasting, CRM discipline, and market visibility across acquisition pathways, competitive activity, and customer priorities.

Who You Are

You’re a strategic seller with a strong record of winning in complex, highly regulated, or mission-critical environments. You know how to navigate long sales cycles, influence multiple stakeholders, and create momentum in markets where credibility matters.

You bring:

• 10+ years of success in business development, enterprise sales, or strategic account growth across federal, defense, critical infrastructure, or other complex security markets.
• Strong domain expertise in DoD markets-particularly U.S. Air Force, Army, and Navy, with verifiable experience in product testing, certification, and authorization processes, including established access to relevant stakeholders and resources.
• An established network across end users, channel partners, systems integrators, consultants, architects, engineers, or prime contractors in the U.S. market.
• Experience creating end-user demand and leading opportunities in collaboration with sales, engineering, and partner teams.
• Knowledge of federal procurement, contracting, proposal response, and the commercial dynamics of high-security opportunities. FAR & DFAR experience a plus.
• Technical credibility across physical security and ideally adjacent areas such as cyber, cloud, identity, SIEM, or enterprise platforms.
• Strong communication, qualification, negotiation, and closing skills, with the drive to work autonomously and deliver results.
