About The Position

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.

Requirements

• U.S. Citizenship is required
• Bachelor's degree in Information Technology, Computer Science, Cybersecurity, or related field
• 6–10 years of hands-on technical experience with a primary focus in Security Operations and Incident Response, supported by strong IT and systems engineering fundamentals.
• Must possess experience with CrowdStrike.
• Proven track record running end-to-end incident response (monitoring, triage, investigation, containment, and recovery) in production environments.
• Solid grasp of endpoint administration, identity and access management (IAM), MDM, and secure configuration of modern cloud/SaaS environments.
• Direct experience with Google Workspace and CrowdStrike (or equivalent EDR) is strongly preferred.
• Practical scripting capability (Python or equivalent) used to automate manual processes and operational tasks.
• Working knowledge of vulnerability scanning tools, risk prioritization, and collaborating across teams to drive remediation.
• Strong builder’s mentality with the ability to turn strategic roadmaps into functional systems, workflows, and documentation.
• Clear written and verbal communication skills, capable of explaining technical security risks to both engineering teams and leadership.
• U.S. citizenship and the eligibility to obtain and maintain a U.S. government security clearance.

Nice To Haves

• Experience in defense or government contracting environments, including familiarity with CMMC, NIST 800-171 / NIST 800-53, and CUI handling procedures.
• Prior experience standing up a security operations capability or IR program from an early stage.
• Direct experience with the CrowdStrike Falcon platform is required. Active CrowdStrike certifications—such as CCFA (Administrator), CCFR (Responder), CCFH (Hunter), CCFP, or specialized cloud/identity certs (CCCS / CCIS)—are highly desired.
• Industry certifications such as GCIH, GCFA, Security+, CySA+, GSEC, or CISSP (valued, but secondary to practical hands-on experience).
• Active or current U.S. government security clearance.

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.
• Execute Security-Focused IT Engineering: Configure and harden endpoints, identity/access systems, and cloud/SaaS platforms. Support secure system administration, onboarding/offboarding controls, MDM, and the operational foundation of our security posture.
• Build Program Operational Muscle: Under the Director’s guidance, establish and mature the processes, runbooks, and tooling required to keep us aligned with CMMC / NIST 800-171 standards and CUI obligations.
• Automate Toil: Script repetitive work (enrichment, response actions, reporting, provisioning) using Python or equivalent languages so the security program scales efficiently.
• Document & Level Up the Organization: Create clear runbooks and documentation while actively raising the overall security IQ of the broader team.
