Security Engineer

Company Description

Air is the leader in Enterprise Readiness. Our mission is to establish readiness as a real-time condition that is continuously achieved. Today, a dangerous Readiness Gap exists between what the front line needs and what is delivered. Our AI-native platform, Air Enterprise Readiness, aligns development, production, delivery, and sustainment into one coordinated execution system for government agencies and industrial suppliers. By revealing true capacity, exposing real constraints, coordinating resources, and executing at the speed of operational demands, the front line gets what it needs to succeed.

Job Description

We are seeking a highly motivated and versatile Security Engineer to help build, establish, and mature our security organization from the ground up. In this role, you will report directly to the Director of IT & Security, serving as a 'Swiss Army Knife' operational builder who can translate high-level vision into actionable security capabilities by designing, implementing, and running foundational programs like Incident Response and Vulnerability Management. You will serve as both a strategic architect and a hands-on technical builder, responsible for developing practical security processes and actively executing them day-to-day.

In order to do this job well, you excel in fast-paced environments where ownership and technical agility are paramount. You bring a strong balance of deep security expertise, problem-solving ingenuity, and operational discipline, with a proven track record of taking security initiatives from blank canvas to full operational reality. You are a natural builder who thrives on solving complex technical challenges, establishing scalable workflows, and working cross-functionally to champion a strong security culture across the company.

Scope of Responsibilities

• Run Daily Security Operations: Monitor alerts across our environment—Google Workspace, CrowdStrike (endpoint/EDR), cloud, and network—triage what matters, and drive issues to resolution. Tune tooling to reduce noise and keep focus on real threats.
• Own Incident Response: Lead the complete IR lifecycle (triage, investigation, containment, eradication, and recovery). Build and exercise playbooks, run tabletops, lead active response efforts, and feed lessons learned back into security controls.
• Own Vulnerability Management: Run scanning, prioritization, and remediation tracking across endpoints, servers, and cloud environments. Partner closely with IT to drive actual remediation, not just issue reports.
