So if you're someone who thinks big, moves fast and wants to make an impact right from day one, then get ready to join our industry-changing team. Let's go! Your Mission As an Offensive Security Engineer, you'll act as an in-house attacker; finding and proving the risks that matter before anyone else can. You'll play a key role in helping us build secure-by-default products by bringing an offensive mindset into everyday engineering decisions. Working closely with engineers, product managers, and DevOps, you'll uncover real-world attack paths, challenge assumptions, and help teams fix issues in a practical, scalable way. If you enjoy getting hands-on, digging deep into systems, and turning complex vulnerabilities into clear action, this is where you'll thrive.
Responsibilities
- Perform in-depth penetration tests across web apps, APIs, and infrastructure-going beyond automated tools to uncover meaningful flaws
- Develop clear, impactful PoCs that demonstrate real risk and help teams prioritize fixes effectively
- Collaborate closely with engineers to guide remediation and validate fixes through re-testing
- Contribute to threat modeling and design reviews, helping identify security gaps early in the SDLC
- Build and refine scripts, tools, and testing approaches to improve coverage and efficiency
Requirements
- 3-5+ years of hands-on experience in offensive security, penetration testing, or product security
- Strong understanding of common vulnerabilities (OWASP Top 10, SANS 25) and how they manifest in real systems
- Practical, hands-on mindset; comfortable testing, exploiting, and explaining vulnerabilities end-to-end
- Able to clearly communicate technical findings and recommended fixes to engineering teams
- Curious and persistent; you enjoy digging deeper, connecting dots, and understanding how things break
