Technical Manager - Information Security

About The Role:

What You’ll Do:

• Day-to-Day
• Advance the detection and response program at a strategic level, leading coverage across Cloud, SaaS, Endpoint, and Identity domains.
• Implement organization-wide automation approaches that reduce alert fatigue and accelerate response across all security tooling.
• Continuously mature SIEM and cloud-native logging architectures, ensuring a highly functional, cost-aware telemetry pipeline spanning corporate, manufacturing, and engineering environments.
• Define and implement scalable security controls that strengthen cloud and infrastructure security through detection, configuration standards, and automated enforcement.
• Drive long-term improvements to cloud and infrastructure security posture through measurable, repeatable, and auditable security processes.
• Ensure 24/7 network operational coverage through on-call rotation and escalation protocols.
• Security Tool Management
• Own end-to-end lifecycle management of the enterprise security toolset including, deployment, configuration, tuning, and decommissioning.
• SIEM platforms, Endpoint Detection and Response (EDR)/Extended Detection and Response (XDR) tools, vulnerability scanners
• Network Traffic Visibility solutions
• Manage SIEM operations including data source onboarding, log normalization, correlation rule development, and alert tuning to minimize noise and maximize fidelity.
• Develop and enforce network device hardening standards across all managed security platforms.
• Team Leadership and Vendor Management
• Lead, mentor, and develop internal technical resources and external security vendors, holding all parties accountable to defined SLAs, quality standards, and security outcomes.
• Serve as the primary escalation point for internal team members and external vendor partners during incidents, complex technical issues, and project delivery challenges.
• Partner with managed security service providers (MSSPs) and specialized security vendors to extend team capabilities, conducting regular performance reviews and contract evaluations.
• Influence and mentor engineers across cross-functional teams, raising the overall bar for detection engineering, automation, and cloud security practices.
• Interface with IT leadership, security management, and vendors to develop and implement new solutions that meet evolving business and regulatory requirements.
• Cloud Security and Posture
• Define and enforce cloud security best practices across all cloud workloads, accounts, and organizational units, including IAM least-privilege, resource policy governance, and guardrail enforcement via SCPs.
• Lead implementation and continuous tuning of cloud security services.
• Partner with cloud infrastructure and platform engineering teams to embed security controls into CI/CD pipelines, infrastructure-as-code (IaC) templates, and cloud “landing zone” designs.
• Design and maintain cloud network security architecture including VPC segmentation, security group standards, PrivateLink, WAF rulesets, and configurations.
• Define cloud security configuration standards (CIS Benchmarks, Security Best Practices) and implement automated compliance enforcement via controls.
• Govern IAM strategy across cloud environments, enforcing role-based access, MFA requirements, and service control policies.
• Network Security
• Participate in the design and enforcement of network security policies, including firewall rule management, zero-trust network access (ZTNA), network access control (NAC), and micro-segmentation.
• Oversee network vulnerability assessments and penetration test scoping; ensure timely remediation and deliver clear risk assessment reports to stakeholders.
• Support compliance activities (e.g., NIST, SOC 2, ISO 27001, etc.) through network controls documentation, audit evidence, and remediation execution.
• Create management processes to keep all network equipment current and hardened against known vulnerabilities.
• Threat Detection and Incident Response
• Manage the technical direction for threat detection and response capabilities across SIEM, cloud-native security platforms, and adjacent security tooling.
• Lead threat-model–driven detection strategy, identifying high-risk attack paths and ensuring detection coverage across cloud, SaaS, endpoint, and identity domains.
• Serve as a senior escalation point during complex security incidents, driving technical analysis, coordinating response across teams, and guiding post-incident remediation.
• Identify systemic gaps in detection coverage, telemetry ingestion, and automation logic; lead cross-team efforts to close gaps at scale.
• Implement and mature playbooks that reduce mean time to detect (MTTD) and mean time to respond (MTTR) across the security operations function.
• Analyze network traffic, system logs, and cloud telemetry to identify anomalies, confirm threats, and support security controls validation.
• OT/ICS and Manufacturing Security
• Conduct operational technology (OT) cybersecurity assessments, identifying risks, potential impacts, and prioritized remediation recommendations.
• Design and support implementation of network segmentation strategies for OT/IT convergence environments, including segmented Industrial Control System networks.
• Collaborate with internal engineering and operations teams to assess security posture without disrupting production operations.
• Identify and implement appropriate remote and local access controls for manufacturing systems.
• Architecture and Engineering Standards
• Own, develop, and maintain architectural standards including reference architectures, data flow diagrams, detection pipeline operating models, and security design patterns.
• Design cybersecurity solutions supporting network segmentation, remote and local access controls, and advanced intrusion detection/prevention systems.
• Partner with IT infrastructure, platform, and engineering teams to ensure security is embedded into cloud design, IAM strategy, and network architecture from inception.
• Drive long-term improvements to cloud and infrastructure security posture through scalable detection, configuration standards, and automation.
• Fulfill project requests to support management and mitigation of vulnerabilities across the enterprise environment.
• Policy, Compliance and Governance
• Develop, maintain, and communicate security policies, plans, and procedures in alignment with applicable regulatory requirements (NIST, SOC 2, ISO 27001, as applicable).
• Provide administrative-level technical oversight across network security operations, ensuring audit-readiness and evidence collection for compliance assessments.
• Produce clear, stakeholder-ready risk articulations for identified vulnerabilities and architectural weaknesses, including impact assessments and recommended mitigations.

What You’ll Need:

• Bachelor's degree in Cybersecurity, Computer Science, Information Systems, or related technical field. Equivalent combination of education and experience considered.
• 8+ years of progressive cybersecurity engineering experience, with at least 2–3 years in a technical lead or people management capacity.
• Demonstrated experience managing both internal security engineers and external vendors/MSSPs, with accountability for security outcomes and SLA adherence.
• Hands-on expertise with enterprise SIEM platforms (Splunk, Sentinel, Chronicle, or equivalent) including detection rule authoring, data onboarding, and operational tuning.
• Deep working knowledge of AWS security services: Security Hub, GuardDuty, CloudTrail, Config, IAM, Macie, Inspector, VPC security architecture, and SCPs.
• Experience conducting OT/ICS cybersecurity assessments in manufacturing, industrial, or critical infrastructure environments is strongly preferred.
• Familiarity with threat modeling frameworks (MITRE ATT&CK, STRIDE) and their application to cloud and OT environments.
• Experience developing security automation using SOAR platforms (Palo Alto XSOAR, Splunk SOAR, Tines, or equivalent) and scripting (Python, PowerShell).
