• If you’re the kind of person who spins up a quick Python script to automate a test, roots a phone just to see what’s inside, or finds joy in reverse engineering an app at 2 AM — you’ll fit right in.
• In this role, you’ll hunt vulnerabilities, dissect mobile apps and APIs, and collaborate with a team of world-class testers who live and breathe offensive security.

• Collaborate with teammates to refine methodologies, share research, and continuously push the boundaries of mobile and web security testing.
• Tackle complex problems with creativity; when something doesn’t work, figure out another way. “Scrappy” is a skill set here, not a slogan.
• WHO YOU ARE  You’re a technical problem-solver who thrives on exploration and experimentation.
• You’re comfortable diving into unfamiliar codebases, debugging network traffic, and learning new tools on the fly.

• You can translate technical detail into clear communication and enjoy mentoring or collaborating with others.
• You take ownership, seek out challenges, and are never satisfied with “good enough.” REQUIREMENTS (You must have … )  Bachelor’s degree in a technical field or 6–8 years of equivalent security experience. 2+ years of experience in penetration testing or vulnerability assessment of mobile, web, or IoT apps / devices.
