Senior Staff Security Engineer

We are seeking a Senior Staff Security Engineer who operates at the nexus of high-level strategy and multi-tenant operational excellence. While a traditional internal role secures a single enterprise perimeter, you are responsible for the integrated defense fabric of a vast portfolio of diverse client environments.

You will navigate the complexities of varied compliance needs and legacy technical debt, transforming them into a unified, scalable security posture. This is a technical leadership role designed for an expert who prefers the keyboard and the whiteboard over a people-management track, focusing on the "big picture" of our global security product stack.

Core Responsibilities

1. Strategic Security Architecture & Product Strategy

• Scalable Multi-tenancy: Architect and maintain hardened, isolated security stacks (SIEM, EDR, XDR) designed to scale across hundreds of distinct client environments.
• Product Vetting: Serve as the technical lead for vendor evaluations, "battle-testing" emerging tech to define our global standard offerings.
• Global Standardization: Engineer "Gold Image" baselines and automated deployment templates based on CIS and NIST frameworks to ensure rapid, secure onboarding.

2. Tier 4 Escalation & Forensic Mastery

• Final Authority: Serve as the ultimate technical escalation point for the SOC, leading the response to sophisticated APTs and complex breaches.
• Post-Mortem Leadership: Conduct deep-dive Root Cause Analysis (RCA) and translate incident findings into systemic, fleet-wide preventative measures.

3. Security Engineering & Hyper-Automation

• Security as Code: Build the automation tissue that connects our stack, utilizing Python, PowerShell, and Terraform to automate threat containment and patch management.
• Integration Engineering: Develop custom API integrations to bridge gaps between vulnerability scanners, RMM tools, and ticketing systems for seamless auto-remediation.

4. High-Stakes Advisory & Governance

• Strategic vCISO: Act as a high-level advisor for key accounts, translating abstract risk into actionable business roadmaps for C-suite stakeholders.
• Compliance Orchestration: Oversee technical evidence collection and governance for HIPAA, SOC 2, and CMMC, ensuring our clients remain audit-ready.

Technical Profile

Experience & Qualifications

• 8–12+ Years in Information Security, with a significant background (3+ years) in multi-client consulting or MSP environments.
• Force Multiplier: Proven track record of leading cross-functional projects and mentoring senior engineers without direct-report authority.
• Bilingual Communication: The rare ability to pivot from a deep-dive technical audit with an engineer to a risk-based ROI presentation for a CEO.

Why This Role?

In a traditional corporate environment, you protect a centralized network. At an MSP, you are designing the security blueprint for an entire sector of the economy. > The MSP "Hidden" Mandate:

This isn't about maintaining a single environment; it’s about engineering resilience across a global footprint. You will have the autonomy to choose the tools, the authority to set the standards, and the responsibility to safeguard hundreds of organizations simultaneously.
