  • Develop an extensive knowledge of the technical architecture and business functionality of Galaxy products
  • Engage with vendors to help shape our Agile Pentesting Program
  • Provide guidance to development and SRE teams on the mitigation of vulnerabilities
  • Advocate of security testing to software engineering and product teams, and help them develop a mindset of thinking about adverse scenarios and how a system can be subverted
  • Stay informed of the latest developments in adversarial tactics and techniques - especially in financial and digital asset space - and adapt the strategy or tooling to address new threats

  • Security certification in cybersecurity testing (OSWE/OSCP/OSWA/eWPTX/BSCP or equivalent)
