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
