  • Implementing and improving vulnerability management processes
  • Embedding security tooling into CI/CD pipelines and development workflows
  • Partnering with developers to promote secure coding practices
  • Reviewing cloud infrastructure and architecture from a security perspective
  • Supporting incident response and remediation activities when required
  • Defining and promoting security standards, policies and best practices
  • Influencing technical decision-making across engineering and leadership teams

Requirements

  • Commercial experience as a Security Engineer, Application Security Engineer, Product Security Engineer or DevSecOps Engineer
  • Strong understanding of application security principles and secure software development practices
  • Experience working closely with software engineering teams
  • Hands-on experience securing cloud environments (AWS, GCP or Azure)
  • Experience with vulnerability management, threat modelling and security reviews
  • Knowledge of CI/CD security and modern development practices
  • Excellent stakeholder management and communication skills

What we offer

  • Hybrid working model
  • Opportunity to work on cutting-edge AI and technology products
