The Opportunity:

Everyone knows security needs to be baked into an enterprise architecture—you know how to make it happen. You identify structural vulnerabilities and translate technical risks into clear business-risk metrics. What if you could use your security architecture expertise to help protect the client's enterprise environment? We’re looking for a lead security architect to shape solutions that strengthen security across a complex hybrid enterprise.

As a lead security architect at Booz Allen, you’ll serve as the primary security architecture advisor. You’ll lead design, threat-modeling, and remediation sessions with the CISO office, Network Engineering, Endpoint Management, and external vendors and partners. You’ll author an enterprise security architecture roadmap aligned with CISO goals and business needs across edge and network defense, cloud security, transport security, endpoint protection, and certificate lifecycle management. You’ll also advise on planning and operations for CISO Engineering Security Edge workstreams.

You’ll lead proactive architecture reviews and continuous monitoring across the client's global hybrid environment to identify structural weaknesses and recommend remediation. You’ll help establish and enforce infrastructure security policies and advance security automation. This is a chance to strengthen security across a large-scale enterprise while working across edge and perimeter defense, cloud, PKI, endpoint protection, and security operations.

Work with us as we protect and advance postal services across the country.

Join us. The world can’t wait.
