Why You Should Join Us

Plaud is building the next generation intelligence infrastructure and interfaces to capture, extract, and utilize intelligence from what people say, hear, see, and think.

• Plaud is a bootstrapped, skyrocketing, profitable company with a $300M revenue run rate achieved in just three years.
• Define the next-gen paradigm for human-AI interaction.
• Gain exposure to cutting-edge AI for Pro tools and play a direct role in our global expansion.
• Work with passionate teammates who value innovation, collaboration, and customer success.
• Grow your career in a culture that champions continuous learning and fast career development.
• Market-competitive compensation, global exposure, and a vibrant, creativity-fueled work atmosphere.

What you will do

• You will own both the detection & response layer and the cloud infrastructure security foundation at Plaud - two domains that must operate in lockstep to deliver SOC 2 Type II audit readiness by Q4 2026.
• Cloud & Infrastructure Security - Remediate credential exposure across AWS/GCP production environments, deploy and tune CSPM across all accounts, embed IaC security gates (Checkov/Terraform) into CI/CD, and implement Zero Standing Privileges via JIT/CIEM.
• SIEM Build & Detection Engineering - Deploy the SIEM platform and author 30+ MITRE ATT&CK-mapped detection rules spanning cloud telemetry, endpoint, and SaaS - with ongoing tuning to reduce false positives and maintain coverage fidelity.
• Incident Response - Own the IR lifecycle end-to-end: develop playbooks across a minimum of 4 incident categories, lead cross-functional response for P1/P2 events, and drive MTTD to ≤60 minutes.
• SOC 2 TII Operational Evidence - Produce and maintain the continuous evidence package required for audit - log retention, alert records, control review cadences, and written control narratives for Cloud Security and SecOps domains.
• Security Reporting & Risk Governance - Publish monthly security reports to leadership, deliver H1 risk governance reports, and maintain vulnerability SLA compliance ≥90% with clear remediation tracking.

Skills, qualifications and experience we look for

• 5-8 years of hands-on security engineering experience with demonstrable depth in at least one of: cloud security (AWS/GCP, CSPM, IAM, IaC) or security operations (SIEM, IR, SOAR, detection engineering) - and working fluency in the other.
• Proven ability to build security infrastructure from zero: tool selection, baseline configuration, and policy definition without inheriting a mature program or existing runbook.
• Strong working knowledge of MITRE ATT&CK, CIS Benchmarks (L1/L2), cloud-native security tooling (AWS Security Hub, GCP SCC, or equivalent CSPM), and log source integration across cloud and endpoint layers.
• Familiarity with SOC 2 TII control requirements - specifically CC6 (logical access), CC7 (monitoring & detection), and the operational evidence standards expected by a third-party auditor.
• Routinely uses LLMs as part of daily security workflow - alert summarization, detection rule generation, SOAR playbook drafting, or IaC policy automation. Will demo last-2-weeks AI usage during interview.
