Nice to have

  • Prior fintech/Trading/OTC product security experience or familiarity with custody/signing patterns.
  • Practical experience designing or deploying AI-assisted security tooling, leveraging LLMs for automated software patch generation, or evaluating vulnerability detection agents within enterprise developer pipelines.

  • Advanced credentials such as OSCP, OSWE, CISSP or equivalent.

What you get

  • Unlimited vacation policy; work hard and take time when you need it.

Worth weighing

  • Role involves significant hands-on responsibilities, which may not suit those looking for a purely strategic position.
  • In-office presence required four days a week, which may limit flexibility for some candidates.
  • No specific salary range mentioned, which could be a consideration for candidates evaluating compensation.
