Cyber Defense Platforms Staff Engineer

Overview

As the Associate Director (Staff Engineer) for Cyber Defense Platforms, you will own the defense technology stack end-to-end: SIEM, SOAR, EDR, DLP, email security, and anti-phishing platforms, along with the detection content, automation, and tooling that make them effective. This is a senior individual contributor role with enterprise-wide impact: every alert triaged, threat detected, and incident contained across the company depends on the systems you build and operate. This is a hybrid position and will be primarily based in Cambridge, MA.

Responsibilities

• Own the deployment, configuration, administration, and lifecycle of defense platforms including SIEM, SOAR, EDR, DLP, email security, and phishing
• Define the platform roadmap: evaluate, deploy, integrate, and rationalize security technologies to maximize defensive coverage and operational efficiency
• Engineer and maintain security data pipelines across the enterprise: log source onboarding, normalization, enrichment, retention, and cost management
• Own the detection content lifecycle end-to-end: development, testing, tuning, versioning, and retirement of rules and analytics across all platforms
• Establish detection-as-code practices, including version control, peer review, CI/CD deployment, and automated validation of content
• Map detection coverage to MITRE ATT&CK, identify gaps, and partner with threat intel, IR, and offensive security to convert findings into durable detections
• Design and build SOAR playbooks and workflow automation that reduce manual analyst effort and accelerate triage and response, including automated handling of user-reported phishing
• Build internal tooling, integrations, and APIs that connect security platforms to each other and to enterprise systems
• Set the standards for how Cyber Defense builds, deploys, and operates its technology, and serve as the technical authority for the defense technology domain
• Lead cross-functional technical initiatives across IT, infrastructure, and engineering teams, and mentor engineers and analysts across the broader team

Qualifications

• 8+ years of progressive experience in security engineering, security operations, or detection engineering, with demonstrated ownership of defense and security platforms
• Deep hands-on expertise architecting and administering: SIEM, SOAR, EDR, DLP, or email security and anti-phishing platforms
• Strong software engineering skills in a language commonly used for security automation (e.g., Python, Go, PowerShell), with experience building production-quality integrations and tooling
• Proven experience building and managing detection content at scale, measured against frameworks like MITRE ATT&CK
• Track record of delivering measurable operational improvements through automation, such as reduced response times or expanded capacity without added headcount
• Ability to operate autonomously in a build-from-zero environment and drive technical work across teams you don't manage
• Experience standing up or modernizing a security operations stack (SIEM migration, SOAR implementation, EDR rollout) from early maturity
• Cloud security experience, particularly AWS-native security services
• Experience in regulated industries (pharma, biotech, healthcare, financial services)
• Relevant certifications (e.g., GIAC GCDA/GDAT/GCIA, CISSP) or equivalent expertise
