Senior individual-contributor role to design, build, and operationalize security controls for enterprise AI systems. Responsibilities include hardening AI hosting environments (cloud-native, Kubernetes), protecting prompts and sensitive data, improving detection/telemetry for model misuse, integrating controls into CI/CD and ML lifecycles, evaluating AI security tooling, and enabling cross-functional teams with secure implementation patterns and guidance.

Lead product-layer security: perform architecture and threat reviews, define secure SDLC and standards, build security tooling and automation, operationalize AI security patterns, prototype security implementations, and advise engineering on risk and architecture while contributing to incident response.

The role involves leading vulnerability detection efforts, developing detection solutions, collaborating with teams, and managing projects in the cybersecurity space.

The Lead Security Engineer will oversee the corporate security posture, manage identity and access management, and mature the company’s Zero Trust network while collaborating across departments to enhance security protocols using AI.

As a Lead Security Engineer, you'll secure corporate systems, manage identity and access management, mature security architecture, and lead teams in AI-driven projects while delivering complex solutions across multiple teams.

Analyze, implement, and maintain security systems across endpoint, network, cloud, and SOC applications; manage EDR/CSPM/NSM tooling, review firewall change requests, respond to security events, map defenses to threat frameworks, contribute to incident response, risk management, and automation/scripting for security operations and policy documentation.

Design and implement security architectures, validate solutions, integrate hardware and software, while analyzing adversary threats and proposing countermeasures.

Build and own detection tooling and logging/alerting systems, create and tune analytics for threat detection, investigate and triage incidents (on-call), drive incident response across teams, and help define and execute detection and response strategy with a detection-as-code mindset.

The role involves designing security architectures, implementing security countermeasures, and leading an engineering team to defend systems against vulnerabilities.

The Principal Systems Security Engineer designs security architectures, implements countermeasures, and collaborates on advanced security solutions to protect critical technologies.

Build and operate high-signal detections across cloud, identity, endpoints, and SaaS. Improve detection platforms, automation, and triage tooling (including LLM-based workflows). Translate threat TTPs into telemetry and detections, participate in incident response/on-call, track metrics like MTTD and alert quality, and drive detection engineering improvements across the org.

Design, implement, and operate Palo Alto Networks firewall solutions; configure policies and threat prevention; lead security integrations for acquired entities; analyze logs and incident response; use automation and AI-assisted tools to improve operations and documentation; follow change and incident management processes.

Lead platform cybersecurity for X-Bat across aircraft, mission systems, networks, ground systems, and support infrastructure. Define security architecture and requirements, drive RMF/STIG compliance, vulnerability management, and accreditation, and coordinate cross-functional integration and testing to ensure mission resilience and fielding readiness.

Lead security enablement and automation for enterprise application onboarding. Design authentication/authorization patterns (SAML, OAuth2, OIDC), build automation, reusable tools/APIs, and self-service workflows. Partner with application and product teams to ensure secure integrations, perform risk assessments, enforce compliance, and mentor junior engineers.

Design, build, and operate enterprise identity, endpoint, and security systems. Automate lifecycle management, access governance, EDR operations, and endpoint hardening. Develop AI/automation agents to eliminate manual work, run enterprise security metrics, support incident response, and establish secure-by-default SaaS onboarding standards.

Detect, investigate, and respond to security incidents; maintain logging and SIEM operations; build detections and visibility; support PCI/SOC2/ISO audits; manage endpoint, email, and GitHub security; collaborate across teams and improve on-call and security tooling.

Design and build agentic AI orchestration and MCP systems to automate SOC workflows. Architect proactive threat hunting, E2E incident response automation, purple-team feedback loops, and simulation testing. Serve as a technical escalation lead and collaborate across Cloud, DevOps, Compliance, and Security teams to drive automation-ready systems.

Design and implement defense-in-depth security architectures and embedded software on complex processors. Analyze adversary threats, propose countermeasures, implement and test software per U.S. Government guidance, work with NIST cryptographic algorithms and S-SOTA technologies, and provide technical leadership in a multi-disciplinary team.

Lead application security efforts end-to-end: own vulnerability management, API and supply chain security, integrate security into design reviews and CI/CD, develop automation and tooling (SAST/SCA/DAST/container/dependency), perform threat modeling, triage vulnerabilities, and support incident response and remediation across engineering teams.

Design, implement, and maintain secure networking across hybrid and multi-cloud (AWS/Azure/GCP). Build secure architectures for containerized applications, apply segmentation and zero-trust, configure cloud-native network controls, deploy IDS/IPS and monitoring, investigate incidents, remediate vulnerabilities, and automate security policy enforcement using IaC, CI/CD, and Python scripting. Mentor engineers and influence platform security strategy.

Design and harden on-device security for Specs including permissions, sandboxing, secure IPC, and trusted execution. Build privacy and integrity controls for on-device AI, improve fuzzing and automated security testing, conduct threat modeling, vulnerability assessment, and secure code review across OS, firmware, services, and device-cloud surfaces.

The Senior Staff Security Engineer will lead edge and network security strategies, overseeing design, operation, and incident response for Gusto's security posture, requiring substantial expertise in Cloudflare and AWS.
