What you will do

You will own one or more of the following security domains.

Deep expertise in 1-2 areas is what we look for — you don't need to cover all six. Tell us your primary domain(s) when you apply.

1. Cloud & Infrastructure Security

Secure Plaud's AWS/GCP environments: remediate credential exposure, deploy CSPM, embed IaC security gates (Checkov/Terraform in CI/CD), and implement Zero Standing Privileges (JIT/CIEM).

1. Data Security

Build the data protection foundation: design L1-L5 classification for audio/transcription/PII, map data flows, implement WORM access audit logs, and govern Snowflake/database permissions.

1. Application Security & AI Security

Own secure SDLC: integrate SAST/DAST into CI/CD, defend against Prompt Injection and LLM threats (OWASP LLM Top 10), and conduct security reviews for product releases.

1. Hardware & Firmware Security

Validate Plaud's hardware (Sigma) against EN 18031: own Secure Boot, OTA dual-key signing, PKI lifecycle, HBOM+CVE supply chain scanning, and PSIRT operations.

1. Security Operations

Build and run the SIEM platform (30+ MITRE ATT&CK-mapped; detection rules), establish IR playbooks, own MTTD/MTTR metrics, and produce monthly security reports for leadership.

1. Enterprise IT Security

Drive 100% EDR and MDM coverage, roll out Okta SSO/SCIM across the SaaS stack, and build a measurable security awareness program alongside the IT team.

Skills, qualifications and experience we look for

• 5+ years of hands-on security engineering experience with deep expertise in at least one domain: cloudsecurity (AWS/GCP, CSPM, IAM), data security (classification, DLP, audit logging), application/AI security(SAST, DAST, LLM/Prompt Injection), hardware/firmware security (embedded systems, PKI, EN 18031),security operations (SIEM, IR, SOAR), or enterprise IT security (EDR, MDM, IdP/SSO).
• Proven ability to build security controls from zero in a fast-moving environment — scoping work, selectingtools, and delivering independently without a pre-existing framework.
• Cross-domain awareness: even if your depth is in 1-2 areas, you can reason about how cloud, data, product,hardware, and operational security interlock — and communicate risk clearly to engineering and leadership.
• Familiarity with relevant standards and frameworks as applicable to your domain: NIST CSF, CISBenchmarks, OWASP / OWASP LLM Top 10, MITRE ATT&CK, SOC 2, ISO 27001, EN 18031, GDPR/PIPL.
• Experience using AI tools (LLM-assisted triage, automated CSPM, AI coding tools) to amplify security output— or genuine curiosity to adopt them in your workflow.
