• Own least-privilege IAM policies, guardrails, workload identity federation, and hardened landing-zone standards using Infrastructure-as-Code
• Proactively hunt across cloud control plane, data plane, and workloads for living-off-the-land techniques, supply-chain compromise, and AI-specific threats
• Build and maintain security automation to reduce MTTD/MTTR
• Partner with internal red team and external pentesters to validate detections and drive remediation
• Mentor engineers on secure cloud patterns and deliver threat briefings
• 8–10+ years of hands-on experience in cloud security and incident response
• Expert-level operational experience with at least two of AWS, GCP, or Azure
• Proven track record leading complex, real-world incident response in cloud environments
• Strong scripting/programming skills (Python/Go + heavy Terraform or equivalent IaC)
• Deep knowledge of cloud attack techniques
• Experience writing and tuning detection rules in Splunk, Elastic, Panther, Datadog Security, or similar

Good to Have

• Contributions to open-source detection content or DFIR tools
• Prior offensive experience (red team, pen testing) applied to blue-team outcomes
• Familiarity with MITRE ATT&CK for IaaS/PaaS and the emerging AI Threat Matrix

Perks & Benefits

• Health & Wellness: Health care coverage designed for the mind and body
• Flexible Downtime: Generous time off helps keep you energized for your time on

We are looking for a Senior Security Engineer with 8–10 years of hands-on experience to be a force multiplier in our Cloud Security and Incident Response program. This is a deeply technical, individual-contributor role reporting to the Associate Director of Security Engineering in a high-velocity, AI-first company.

You will own detection, response, and hardening for our multi-cloud environment (AWS, GCP, Azure) while driving real-time defense against sophisticated threats targeting our infrastructure and AI workloads.

This is a “boots-on-the-ground” role: you’ll hunt threats, lead incidents, write detection logic, harden cloud configurations with code, and eliminate entire classes of risk before attackers can exploit them.

The Impact

• Be the tip-of-the-spear defender for petabyte-scale AI infrastructure.
• Directly stop nation-state and financially motivated attackers.
• Equity in a high-growth AI company.
• Remote-first, global team with deep trust and autonomy.
• Work side-by-side with world-class platform engineers and AI researchers.

Key Responsibilities

• Cloud Threat Detection & Response Build, tune, and operationalize high-signal detection content (Sigma, YARA-L, cloud-native logs, EDR) across AWS, GCP, and Azure. Lead investigation and response for cloud-native incidents end-to-end.
• Incident Commander & Forensics Serve as on-call Incident Commander for major security events. Perform rapid compromise assessment, memory forensics, cloud artifact collection, and root-cause analysis.
• Cloud Platform Hardening Own least-privilege IAM policies, guardrails (SCP, Azure Policy, Config rules), workload identity federation, and hardened landing-zone standards using Infrastructure-as-Code (Terraform, Pulumi, Crossplane).
• Threat Hunting Proactively hunt across cloud control plane, data plane, and workloads for living-off-the-land techniques, supply-chain compromise, and AI-specific threats (model theft, training data exfil).
• Automation & Tooling Build and maintain security automation (SOAR playbooks, Lambda/SOAR responders, custom detection tooling) to reduce MTTD/MTTR.
• Red Team Collaboration Partner with internal red team and external pentesters to validate detections and drive remediation of systemic cloud risks.
• Security Champions & Enablement Mentor engineers on secure cloud patterns and deliver “lunch-and-learn” threat briefings tied to real incidents.

Required Qualifications

• 8–10+ years of hands-on experience in cloud security and incident response.
• Expert-level operational experience with at least two of AWS, GCP, or Azure (the third is a strong plus).
• Proven track record leading complex, real-world incident response in cloud environments (ransomware, APT, credential abuse, etc.).
• Strong scripting/programming skills (Python/Go + heavy Terraform or equivalent IaC).
• Deep knowledge of cloud attack techniques: IAM privilege escalation, container escapes, SSRF to metadata, living-off-the-cloud, etc.
• Experience writing and tuning detection rules in Splunk, Elastic, Panther, Datadog Security, or similar.
• Relevant certifications (preferred): GCIH, GCFA, GNFA, AWS Certified Security – Specialty, Azure Security Engineer, Google Professional Cloud Security Engineer, CCSP.

Preferred Skills

• Experience responding to AI-specific incidents (training cluster breaches, model exfiltration, poisoned datasets).
• Contributions to open-source detection content or DFIR tools.
• Prior offensive experience (red team, pen testing) applied to blue-team outcomes.
• Familiarity with MITRE ATT&CK for IaaS/PaaS and the emerging AI Threat Matrix.

Who You Are

• Hunter mindset: You treat “quiet” as suspicious and go looking for evil.
• Ownership obsessed: You close incidents with permanent fixes, not just tickets.
• Calm under fire: You’ve led war rooms at 3 a.m. and kept everyone focused.
• Cloud-native: You think in resources, policies, and API calls—not checkboxes.
• Communicator: You turn forensic findings into clear, actionable stories for engineers and leadership.

If you live for the moment an alert fires, love chasing attackers through cloud logs, and want to defend the infrastructure powering tomorrow’s AI—this is your role.
