• Solid understanding of web application security, network security, and API security testing
• Able to think like an attacker — creative, persistent, and methodical in finding what others miss
• Strong written communication skills — you can translate complex technical findings into clear, actionable reports
• Self-motivated and reliable when working independently without direct supervision
• Comfortable working across diverse technology stacks and environments

Nice to Have

• Relevant certifications such as OSCP, OSCE, CEH, GPEN, GXPN, or eWPT
• Experience with AI/ML security testing — adversarial machine learning, prompt injection, LLM red-teaming
• Background in red teaming, bug bounty programs, or CTF competitions
• Familiarity with cloud security (AWS, GCP, Azure) and container security
• Programming or scripting skills in Python, Bash, PowerShell, or similar
• Knowledge of secure development practices and DevSecOps workflows
• Experience conducting security assessments in compliance-driven environments (SOC 2, ISO 27001, etc.)
