What you'll do
- Build and improve SIEM detection rules, alert pipelines, and automated response playbooks (Datadog SIEM, CrowdStrike, Cloudflare)

- Drive application security initiatives: threat modelling, secure code review support, API testing, and security pipeline improvements
- Assess and secure AI/agentic workflows across the company — reviewing prompts, preventing destructive actions, and controlling data exposure
- Establish and run the vendor security assessment process — building a scalable due diligence framework for third-party onboarding
What you'll need
- 4–7 years in information security, ideally having built or significantly shaped the security function at a startup or high-growth company - you've been the person who sets things up, not just maintains them
- Hands‑on experience with cloud infrastructure security (AWS, Kubernetes)
- Working knowledge of SIEM platforms and detection engineering - you've written detection rules, not just consumed alerts
- Familiarity with application security practices: threat modelling, secure code review, CI/CD pipeline hardening, and API security testing
- Experience with endpoint security tooling (EDR/XDR) and identity & access management in a SaaS‑heavy environment (Google Workspace, Okta/Cloudflare Access, SSO/SCIM)
- Ability to assess and secure emerging AI/agentic tooling - you understand the risks of LLM integrations, MCP servers, and automated workflows, and can define practical guardrails
- Experience running or contributing to vendor security assessments and third-party due diligence
- Strong written and verbal communication
- Business fluent in English; Spanish or Portuguese a plus
