We’re hiring a  Senior Security Engineer  to take full ownership of vulnerability management and embed security into the heart of engineering. This is a high-impact, high-visibility role where you’ll influence how software is built, not just review it after the fact.

Responsibilities: 

  • Own the  vulnerability management programme  end-to-end
  • Embed security across the  SDLC —from design to deployment
  • Be a  visible voice in engineering —raising issues early, not reacting late
  • Manage inputs from  SAST, pen testing, and bug bounty programmes
  • Lead  responsible disclosure & CVE coordination  with external researchers
  • Secure cloud environments across  AWS, Azure, Kubernetes & containers
  • Drive standards for  hardened, secure base images
  • Escalate risks when needed—you’ll have leadership backing

Requirements:

  • Proven experience in  vulnerability management  within a tech environment
  • Strong understanding of  how security fits into engineering workflows
  • Hands-on  cloud security experience  (AWS, Azure, Kubernetes)
  • Experience with  CI/CD and code scanning tools
  • proactive mindset —you speak up, challenge, and influence
  • Experience with  responsible disclosure / external researchers
  • Comfortable operating cross-location (Dublin ↔ Porto)

Nice to Have:

  • Terraform / IaC security experience
  • SaaS or product-led environment exposure
  • Pen testing coordination
  • Threat modelling / secure-by-design knowledge

Why This Role?:

  • Own and shape a  growing product security function
  • Work directly with  engineering & product teams
  • Strong backing from leadership to  drive real change
  • International exposure across two key tech hubs

If you’re someone who  leans into engineering, not away from it , and wants to build security into products, not bolt it on, this is worth a conversation.
