About the role
What you'll do
* Build and improve SIEM detection rules, alert pipelines, and automated response playbooks (Datadog SIEM, CrowdStrike, Cloudflare)
* Contribute to incident response readiness, including IR playbooks, tabletop exercises, and forensic procedures
* Support DLP strategy and data protection controls across Google Workspace, Slack, and internal tooling
* Conduct cloud security assessments across AWS and Kubernetes environments
* 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 cyber 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
* 2+ years at a regulated fintech/bank/payment company
* 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
