  • Contribute to business development and client growth by supporting proposal creation, project scoping, thought leadership (e.g., blogs, webinars), and collaborating on presentations, tenders, and workshops with senior team members.
  • A proactive, client-oriented mindset with a passion for continuous learning and improving security outcomes.
