Lead Security Engineer

Locations 730 3rd Ave, 11th Floor, New York, NY, 10017, US (Remote) Base Range Info Compensation for this role will be based on the background of the individual selected for this position. For more details see the “About Us” section. Base Range $111,000 - $180,000 The Lead Security Engineer (Cloud & Enterprise Security Engineering) is a deeply technical, hands‑on engineering role responsible for designing, implementing, hardening, integrating, and continuously improving CBIZ’s enterprise security technologies and controls across cloud, identity, endpoint, network, email, and data protection domains. This position requires strong engineering fundamentals, broad systems knowledge, and the ability to solve complex technical problems across hybrid and multi‑cloud environments. The ideal candidate is an experienced builder and troubleshooter who can translate security requirements into scalable, reliable, and measurable technical solutions. Success in this role depends on advanced expertise in security architecture, platform engineering, automation, systems integration, detection logic, and control validation. The engineer must be able to work across diverse technologies, analyze intricate dependencies, and develop durable solutions that strengthen security posture, reduce risk, and improve operational resilience. This is not a passive monitoring or ticket‑routing role. It is a senior technical position focused on engineering secure‑by‑default solutions, improving platform capabilities, automating security functions, and driving long‑term technical maturity across the environment. While incident support and investigation remain part of the role, the primary emphasis is on building, optimizing, and sustaining the security technologies, integrations, and guardrails that prevent, detect, and contain threats at scale. Essential Functions and Primary Duties Cloud & Enterprise Security Engineering Design, implement, harden, and maintain enterprise security controls and reference architectures across: Amazon Web Services (AWS) Microsoft 365 security and compliance platforms Hybrid identity, endpoint, email, and data protection environments Engineer secure‑by‑default configurations and technical guardrails that reduce attack surface, improve resilience, and support scalable enterprise operations. Translate business, compliance, and security requirements into practical engineering designs and sustainable technical solutions. Evaluate current‑state architectures, identify control gaps, and implement improvements that strengthen security posture while maintaining operational usability. Partner with infrastructure, cloud, networking, systems, and endpoint teams to embed security into enterprise platforms, workflows, and lifecycle processes. Identity, Data Protection & Platform Security Engineer and operationalize controls for identity protection, phishing defense, DLP, conditional access, privileged access, tenant security baselines, and cloud workload protection. Secure workloads, identities, and data across hybrid and multi‑cloud environments through design standards, configuration baselines, and measurable technical guardrails. Support and troubleshoot certificate‑based authentication, encryption, and PKI‑related services, including lifecycle considerations such as issuance, renewal, revocation, and dependency management. Improve authentication security, access control design, and privileged access protections across enterprise systems and cloud platforms. Design and validate visibility and monitoring coverage for cloud, identity, endpoint, email, and platform security events to ensure reliable telemetry and actionable data. Security Platforms, Automation & Tooling Build, administer, and continuously improve core security platforms and integrations, including: SIEM and log ingestion pipelines SOAR and workflow automation platforms XDR/EDR and endpoint security tooling Network and zero trust security controls CASB, DLP, and data security platforms Identity and access management controls Email and collaboration security technologies Develop and maintain automation using PowerShell, Python, Bash, APIs, and workflow tooling to support enrichment, orchestration, reporting, evidence collection, system validation, and control enforcement. Design and optimize log collection, parsing, normalization, retention, and access models to improve searchability, detection quality, auditability, and investigative efficiency. Improve platform reliability, scalability, and maintainability through lifecycle upgrades, engineering standards, technical documentation, and structured change control. Evaluate and responsibly implement AI‑enabled security capabilities where they provide measurable improvements in efficiency, visibility, or control effectiveness. Detection Engineering & Technical Response Support Engineer and refine analytic rules, correlation logic, alerting thresholds, and detection content across cloud, identity, endpoint, email, and network security technologies. Validate detections and controls through testing, simulation, tuning, and gap analysis to improve fidelity and reduce noise. Translate lessons learned from incidents, platform issues, and control failures into durable engineering improvements such as new detections, automation, hardening standards, and preventive safeguards. Contribute to complex investigations and incident response activities as a senior technical resource, including root cause analysis, containment support, and remediation validation. Participate in on‑call or escalation support as needed for significant incidents or high‑priority technical issues. Technical Ownership, Documentation & Continuous Improvement Own complex technical initiatives from design through implementation, support, optimization, and documentation. Balance project‑based engineering work with platform maintenance, technical debt remediation, backlog reduction, and continuous control improvement. Create and maintain actionable documentation including architecture diagrams, standards, SOPs, runbooks, playbooks, and knowledge base content aligned to production reality. Define and track measurable improvements in platform health, control coverage, alert quality, automation effectiveness, and engineering maturity. Serve as a senior technical contributor who establishes patterns, improves standards, and advances overall enterprise security engineering maturity. Partner closely with GRC, IT, Cloud, Networking, Systems, Endpoint, and business teams to develop secure designs and pragmatic technical solutions. Clearly communicate architecture decisions, technical findings, control gaps, implementation plans, and remediation priorities to both technical and non‑technical stakeholders. Provide technical guidance and mentorship to analysts and engineers, helping elevate engineering practices, platform understanding, and troubleshooting capability across the team. Influence cross‑functional stakeholders and help remove blockers to drive timely technical outcomes. Preferred Qualifications 10+ years of experience in Information Security, Security Engineering, Infrastructure Security, or closely related technical roles, including senior or lead ownership of complex security initiatives. Demonstrated hands‑on expertise designing, implementing, and supporting enterprise security technologies across cloud, identity, endpoint, network, email, and data protection domains. Deep experience securing cloud environments such as Azure and/or AWS, and operationalizing Microsoft 365 security capabilities including Defender, email protection, DLP, conditional access, and identity protections. Strong experience securing and supporting Azure Virtual Desktop (AVD) environments, including identity controls, endpoint protections, logging, monitoring, and configuration hardening. Working knowledge of PKI, certificate‑based authentication, and encryption, with the ability to troubleshoot production issues and understand operational and security impacts.
