Requirements
- •5+ years of hands-on infrastructure or detection-and-response security experience
- •Production experience securing a cloud-based identity and collaboration platform at scale beyond default settings
- •Hands-on experience with a modern SIEM and SOAR including writing detections, onboarding log sources, building response playbooks, and tuning to reduce false positives
- •Strong cloud security background including IAM, network controls, workload identity, and organization-level guardrails
- •Practical experience securing a macOS-dominant endpoint fleet including MDM, endpoint hardening baselines, and EDR
- •Familiarity with Infrastructure as Code, secrets management, and security automation
- •Real incident response experience including being on-call for security and leading investigations to conclusion
- •Clear, constructive technical communication across engineering and non-engineering stakeholders
What You'll Do
- •Own the security configuration of identity and collaboration stack including identity and access policies, third-party app governance, DLP, context-aware access, and admin audit
- •Drive least-privilege and phishing-resistant MFA across the organization
- •Build, tune, and maintain detections for detection and response
- •Design response playbooks for high-signal alerts
- •Onboard new log sources and own the detection-as-code pipeline
- •Reduce mean-time-to-detect and mean-time-to-respond on real incidents
- •Harden cloud footprint, Kubernetes clusters, and CI/CD pipelines
- •Review Infrastructure as Code for security regressions and embed guardrails
- •Partner with DevOps on secrets management and supply-chain controls
- •Own the security posture of the endpoint estate including MDM configuration, baseline hardening, EDR tuning, and endpoint telemetry
- •Lead and participate in security incident investigations end-to-end including containment, forensics, root cause, remediation, and post-mortem
- •Improve runbooks and detections after every incident
- •Run threat models and architecture reviews for new internal systems and infrastructure changes
- •Translate findings into concrete, prioritized work
- •Work alongside Protocol Security, DevOps, IT Ops, and Product Engineering
- •Raise risks constructively, write clearly, and influence without owning every system
Nice to Have
- •Blockchain / Web3 exposure including familiarity with security considerations of decentralized infrastructure, validator/sequencer operations, key management for on-chain systems, or hot/cold wallet operations
- •Bonus for Ethereum, Solidity, or ZK-related background
- •Compliance framework experience with SOC 2 and ISO 27001 including building or maintaining controls, evidence collection, control design, working with auditors, and mapping technical safeguards to control criteria
- •Comfort translating compliance requirements into real engineering work without letting compliance dictate engineering
- •Kubernetes security including admission control, runtime detection, supply chain
- •Detection engineering as code including Git-based rule management, CI for detections, purple-team validation
- •Experience in lean security teams owning a domain end-to-end rather than a narrow slice
Benefits
- •Remote-first work model with optional travel to team or industry events
- •Freedom and ownership culture with no time tracking and minimum bureaucracy
