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.

What you'll do

• 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

Who you are

• 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

Your Mission
You operate as a trusted adversary within our systems identifying, exploiting, and helping eliminate the risks that matter most. You don’t just find vulnerabilities; you shape how we think about security at a product and platform level.

You’ll embed offensive thinking across the SDLC, partnering with engineering, product, and DevOps to challenge designs, raise the bar, and ensure we’re secure by default, not by accident.

If you’re the kind of person who sees an attack path where others see “low risk,” and you know how to turn that into real change, you’ll feel right at home.

What you'll do

• Lead sophisticated, end-to-end penetration tests across complex systems; uncovering deep, chained vulnerabilities others miss
• Design and demonstrate impactful exploit scenarios that drive prioritisation at both engineering and leadership levels
• Own offensive security engagements from scoping through remediation validation, acting as the technical authority
• Influence architecture through threat modeling and design review; shifting security left and preventing classes of vulnerabilities
• Build and evolve offensive tooling, methodologies, and playbooks to scale security testing across teams

Who you are

• 5+ years in offensive security with a proven track record of finding high-impact, non-trivial vulnerabilities in real-world systems
• Strong depth in application and product security, with the ability to think across layers (app, API, infra, auth, logic)
• Recognised for your hands-on expertise; whether through certifications (OSCP, OSWE, GPEN) or demonstrated offensive work
• Able to influence without authority; translating complex attack paths into clear, actionable risk for diverse stakeholders
• Naturally curious and adversarial; you think in attack chains, not isolated bugs, and push until you find what really matters
