What recruiters look for in a Security Engineer resume

  • Title-match in the first 6 seconds. The summary and most-recent job title should both read "Security Engineer". Recruiters skim top-to-bottom and bail when titles don't line up.
  • Quantified bullets, every line. Every Security Engineer bullet should carry a number: a percentage, a dollar figure, a count, or a duration. Bullets without numbers get read as "participated in" not "shipped".
  • Show depth, not just breadth. Two skills used deeply (threat modelling, cryptography) beat ten skills listed shallowly. ATS scoring rewards depth signals.
  • Keep it to one page through 8 years, two pages after. Security Engineer hiring managers want signal density. Filler hurts more than helps.
