About The Position

We are seeking a highly technical Security Engineer to join our Public Sector Infrastructure & Security team as a security generalist. As a generalist you will ensure the security and integrity of our products and platform designing and shipping high-precision detections across cloud services and enterprise SaaS. You won't just investigate incidents, you'll build the systems that detect, contain, and prevent them. Your ability to write production-quality code is just as important as your ability to triage an alert. You will structure investigations, analyze root causes, and clearly communicate the significance of security incidents, their impact, and recommended remediation steps — but you'll also turn those findings into durable engineering improvements: better detections, tighter schemas, and smarter automation.

Requirements

At least an active Top Secret clearance. This is a requirement and candidates will not be considered who do not hold at least a Top Secret clearance.

Nice To Haves

Proficiency in NodeJS, TypeScript, Python, and/or Kubernetes.
5+ years of experience in Detection Engineering, Incident Response, or Security Operations, with a strong emphasis on building and shipping security tooling and automation.
Proficiency in at least one programming language (e.g., Python, Go) and comfort writing production-grade code — not just scripts.
Hands-on experience designing or improving detection pipelines, SIEM content, and alerting workflows in cloud-native environments.
Practical experience with SIEM, EDR, and SOAR tools, with a preference for candidates who have built integrations or extended these platforms programmatically.
Strong understanding of modern cyber threats, common attack techniques, and adversary TTPs.
Familiarity with digital forensics tools and malware analysis techniques.
Experience with cloud-native environments (e.g., AWS, GCP, Azure) and the security telemetry those environments generate.
Exposure to threat intelligence platforms and integrating intel into detection and investigation workflows.
Strong communication skills, with the ability to translate complex security findings into clear business impact.
Relevant security certifications (e.g., GCIH, GCFA, GCIA, CISSP, GDSA) are a plus.

Responsibilities

Engineer, test, and deploy detection logic across cloud and enterprise environments, treating detections as software with version control, peer review, and measurable performance.
Build and maintain incident response automation, runbooks, and tooling that reduce containment timelines without sacrificing developer velocity.
Mature telemetry pipelines through improved schema design, normalization, enrichment, and quality checks that reduce false positives and increase signal fidelity.
Perform digital incident investigations to identify and contain potential security breaches.
Conduct digital forensics and malware analysis to understand attack vectors and adversary methodologies.
Integrate alerting with messaging and ticketing systems to enable fast, traceable response workflows.
Partner cross-functionally with IT, security, and engineering teams to harden identity and access patterns, close logging and forensics gaps, and implement maintainable guardrails that scale with the organization.
Utilize threat intelligence platforms to improve hunting, detection, and response workflows.
Clearly explain the significance and impact of incidents, providing actionable recommendations to both technical and non-technical stakeholders.
