  • Proficient in at least two programming languages (TypeScript/JavaScript, Python, Ruby, Java, Go, etc.)
  • Hands-on experience with application penetration testing and code reviews
  • Proficient in threat modeling and risk-based analysis
  • Strong organizational, time-management, communication, and presentation skills
What you'll get from us
A team where you can voice your opinion, make an impact, and where you and your experience are valued. Internal mobility - there are opportunities for cross training and the ability to attain your next career step within Barracuda.
