Senior Penetration Tester

You’ll be on the front lines of our security efforts, thinking like an attacker to help us stay one step ahead. As a Senior Offensive Security Engineer, you’ll break things (responsibly), uncover weaknesses, and help us build stronger, more resilient systems.

This is a hands-on role where you’ll move fast, experiment, and have real impact. You’ll work closely with engineers, product teams, and security to turn findings into fixes — not just reports.

Day to day, you’ll:

• Hack our own systems to find and fix vulnerabilities before others do
• Run white-box and black-box pentests across apps, infrastructure, and APIs
• Triage bug bounty reports and dig into external findings
• Go beyond surface issues with root cause and variant analysis
• Tear apart third-party tools and integrations to understand their risk
• Build scrappy (and scalable) tools for recon, automation, and insights
• Partner with engineers and the SOC to solve real security problems
• Share knowledge through demos, workshops, and hands‑on sessions
• Help us decide where to focus to get the biggest security wins
• Shape and evolve our security programme as we grow

Who You Are

You’re curious, pragmatic, and love breaking things to make them better. You don’t just find problems — you help fix them.

• Have solid experience in penetration testing and offensive security
• Can spot vulnerabilities in code (especially Java and Node.js)
• Understand modern architectures — AWS, microservices, APIs
• Communicate clearly and give practical, actionable remediation advice
• Comfortable scripting and contributing to larger projects in Python
• Take ownership and don’t wait to be told what to do

Nice to have:

• CTFs, bug bounty hunting, or involvement in the security community
